Heating FAQs

When should I replace my furnace?

There are a number of factors that contribute to needing a furnace installation replacement. How old is your furnace? If it’s over 10 – 15 years old, it’s likely time for a furnace replacement—simply because this will improve your energy efficiency.

Other factors include:

  • how well it’s heating your home
  • how often it requires repairs
  • how much it costs to heat your home, etc.

Learn more about when to replace your furnace.

Do I really need a furnace cleaning every year?

Yes! Not only does a furnace cleaning improve the performance and efficiency of your system, but most manufacturer warranties also require annual furnace maintenance to maintain the warranty.

Learn more about annual furnace cleaning.

How can I have lower home heating fuel prices?

With home heating fuel prices on the rise, many homeowners are concerned about their growing utility bills! Find out what you can do to lower your costs with these simple tips!

  1. CHANGE YOUR AIR FILTER REGULARLYCheck your air filter once a month and change it at least every three months. Dirty filters slow down airflow and make the system work harder to keep your home at the right temperature. A clean filter will also prevent dust and dirt from building up in the system. This buildup can lead to big repairs and early system failure later on.
  2. TUNE-UP YOUR FURNACE EQUIPMENT YEARLY – Just like properly maintaining your car can improve your gas mileage, a yearly tune-up of your heating and cooling system can improve efficiency and save you money. Here are 3 reasons to keep a heating system maintenance schedule.
  3. INSTALL A PROGRAMMABLE THERMOSTAT – A programmable thermostat is ideal for people who are away from their homes during set periods of time throughout the week. For example, it can turn the heat down while you are at work and then turn it back up before you get home. This gives you the best of both worlds. You save money during the day and are able to come home to a comfortably warm house. Through proper use of pre-programmed settings, a programmable thermostat can save you around $180 every year in energy costs.
  4. SEAL YOUR HEATING AND COOLING DUCTSSealing and insulating ducts can improve the efficiency of your heating system by as much as 20 percent — and sometimes much more.
  5. CONSIDER INSTALLING NEW HEATING AND COOLING EQUIPMENT – If your HVAC equipment is more than 10 years old or not keeping your house comfortable, have it evaluated by a professional HVAC technician. Before you invest in a new system, make sure you address any big air leaks in your home and duct system. These can be the source of the problem. If your heating system is still not performing as it should, consider replacing it. Our experts can walk you through the process to ensure you get the system you need. Make sure to choose the right HVAC contractor and avoid these common mistakes.

Why does my furnace smell bad when I turn it on?

Ever notice that your furnace smells bad when you turn it on the first time? That nasty smell may be a bother if you’re expecting guests. But at the very least, it is a clear indicator of your furnace requiring maintenance — especially if it smells like burnt hair or dust. There are a few other odors that can indicate some further danger.

Here are a few reasons why your furnace stinks after turning on the heat.

How does heating in a house work?

There are two different types of heating systems:

  1. Forced air systems pull in air from your home, and then use a blower fan to release the hot air back into your home.
  2. Radiant systems use convection and/or radiation from the environment to deliver heat into your home.

Learn about which heating system is best for you and your home.

How much does a new furnace cost?

The cost of a furnace system depends on a lot of factors, such as the type of heating and the materials used in manufacturing. A new furnace may have a more expensive cost upfront, but save you money on fuel usage over time, so it is important to consider all of the different cost factors in order to get a good return on your investment. In this article, we will give you a better idea of how much a new furnace costs and what the prices mean.

How do you dust during the winter?

Spring cleaning is all well and good when the weather is warm outside at the beginning of the year. Unfortunately, dust doesn’t take a vacation and will build up even when it’s not a good season for opening the windows. It’s still important to keep your house dusted and clean, both to preserve the quality of your air and to help increase the lifespan of your central heating and cooling systems by reducing the contaminants that it has to filter out.

Of course, keeping the home dust-free also keeps your home looking beautiful and well-organized, even if there are a few messes here and there (the same can be said for kitchen dishes – clean them and the whole kitchen looks cleaner).

Check out these 7 spring cleaning tips to improve the air you breathe.

What are those pipes sticking out of my house?

We’ve had many customers ask us what are those pipes sticking out of my house for. We also get questions like, “Can they be cut flush with the house?” and “Why are they pointing in different directions?”

To answer these questions and more, we will be discussing what those pipes are used for and why they must be installed the way they are.

It is critical that these pipes remain clear; otherwise, you could risk having leaking condensate damage your furnace and your home.

How do you keep your basement warm during the winter?

Basements tend to be cold. Many homes are not built with ductwork in the basement and hot air rises. So, if there are no heating vents down in the basement, the heater will have little to no effect on it. If you have remodeled your basement as extra living space without considering how to insulate and heat it, you are in for a cold winter.

You are also in for an expensive winter because your heater will have to work harder to keep the basement warm. The best thing to do is to incorporate heating solutions into your remodeling plans, but even if you have already finished remodeling, these solutions are still available to you.

How do I fix my furnace pilot light?

A broken furnace is the last thing you want as winter’s chill deepens around central Iowa. The furnace pilot light is one of the most important components of your furnace, and it’s a common culprit in heating breakdowns.

Take these 3 easy steps to clean your furnace pilot light.

Which Way Does Furnace Air Flow?

Forced air furnaces recirculate air through a home: pushing air (cool or heated) in, and pulling spent air back in for another cycle. So air flows from your ducts, through the filter, and into the furnace.

What’s The Right Furnace Filter Direction?

If you are looking at a furnace filter, find the arrow that indicates the proper airflow direction. That arrow must always face toward the furnace and away from the return duct that carries the air in need of heating or cooling.

How Do I Install A Furnace Filter?

This is pretty easy once you’ve found the arrow mentioned above and inserted it with the arrow facing towards the furnace and away from the return duct. Need more help? Give Service Legends a call and we can help.

What Do Furnace Filter Ratings Mean?

All filters are rated using the Minimum Efficiency Reporting Value, or MERV, scale which goes from 1 to 20. The United States Environmental Protection Agency recommends air furnace filters with a MERV between 7 and 13 for most homes. Check out this chart to see exactly what the ratings mean: MERV Rating Chart and see below for more details on selecting the right filter for you.

What Are The Best Furnace Filters?

What’s the best furnace filter? Well, that all depends on how much you want to spend and what you’re trying to filter.

You need to be aware of the MERV scale (explained above). A furnace filter with a high rating can slow airflow too much, but a low-efficiency filter won’t filter dust very well. When selecting the filter, it’s important to strike the right balance and ALWAYS consult your furnace manual to see the manufacturer’s specifications.

For most homeowners, a MERV 7 or 8 pleated filter provides a good balance between cost and filtration efficiency. These filters trap 80 to 95 percent of the particles 5 microns and larger—more than enough for most homes. However, if you have family members with allergies or an impaired immune system, you may want to invest in a MERV 11 or higher filter. But be warned, you must change these filters regularly to protect your furnace.

How Do I Know If My Furnace Filter is Dirty and Needs Replacing?

There are a few different ways of checking whether the filter is dirty and needs to be replaced:

  1. Examine your furnace filter carefully for the buildup of dirt, dust and other contaminants. A large buildup can be a sign that it’s time to replace your filter.
  2. Listen to the sound of air moving through your furnace. If you remove the filter and there is a significant release of air pressure, this means the buildup of dust and dirt has reduced the effectiveness of the filter. It should be replaced.
  3. Keep an eye on the amount of dust and dirt building up in your home over a set period. If you notice an increase in the amount of dust and dirt on furniture and other household items, it may be time to change the filter.
  4. The easiest and most reliable way of telling whether your filter is dirty and needs to be replaced is installing a filter monitoring system like FilterScan Wifi. This provides automatic monitoring of your filter system and alerts you when it’s time for a replacement. Using FilterScan Wifi means you won’t ever miss changing the filter when it’s necessary to avoid damage or low air quality, nor will you waste money on changing a filter that is still working effectively.

How does a heat pump work?

A heat pump works by transferring heat energy from one source to another. In the winter when your heat pump is acting as a heating system, it extracts heat energy from the outside air (even in near-freezing temperatures), and transfers it into the air in your home. When summertime rolls around, it’s as easy as flipping a switch to change your heat pump to cool mode.

Learn more about how heat pumps work.

Why are heat pumps more efficient?

Heat pumps are one of the most energy-efficient HVAC systems available on the market because they don’t burn fuel to provide heat. In addition to their high efficiency, they can operate as both a heating and cooling system, thus reducing the number of systems that require maintenance, repairs, and replacements.

Should I get a furnace or a heat pump?

The area of the country in which you live is perhaps the biggest factor in your heat pump vs furnace debate. Traditionally, heat pumps are best in areas where winters are more mild – think southern and coastal states. Furnaces offer greater ability to heat your home during harsher, colder winter conditions and are therefore better suited in northern locations. Most furnaces in the U.S. use natural gas for combustion, but propane, oil and electric furnaces are used as well. By selecting a heating system suited to your climate, you can enjoy better comfort and probably lower operating costs as well.

Can a heat pump replace my air conditioner?

If you need to replace your air conditioning system or your entire HVAC, should you consider getting a heat pump for AC? A heat pump can replace your air conditioner, and possibly your heating system as well. But it is important to make sure it’s the right choice for your needs.

Should I get a yearly maintenance contract for my heat pump?

A service contract is a good investment even if your system is still fairly new. Regular service will extend the life of the heat pump and helps to prevent costly repairs in the future.

Why don't more people use heat pumps?

If Americans are going to buy air-conditioners anyway, either for the first time or to replace older units, why not convince them to buy electric heat pumps instead? Although the name can be confusing, an electric heat pump is essentially an air-conditioner that is slightly modified so that it can run in two directions, cooling the home in the summer and providing heat in the winter.

Traditionally, heat pumps are best in areas where winters are more mild – think southern and coastal states. Furnaces offer greater ability to heat your home during harsher, colder winter conditions and are therefore better suited in northern locations like Iowa. Most furnaces in the U.S. use natural gas for combustion, but propane, oil and electric furnaces are used as well. By selecting a heating system suited to your climate, you can enjoy better comfort and probably lower operating costs as well.

Do heat pumps work in the winter?

Yes, heat pumps work in extremely cold temperatures. In the past, some heat pumps worked better in frigid climates than others. However, thanks to technological advancements, most heat pumps on the market today can keep you and your family warm on even the coldest of winter days in Iowa.

Why is R-22 refrigerant being phased out?

HCFC-22, commonly called R-22, has been a common refrigerant used in residential heat pumps and air conditioners for more than 40 years. But releases of R-22, such as those from leaks, contribute to ozone depletion, and the making of R-22 results in a byproduct that contributes to global warming. This refrigerant is now being phased out by the EPA. As of January 2020, chemical manufacturers are no longer able to produce R-22.

Learn more about the R-22 phaseout.

How does central air work?

Central air conditioning works by moving around air in your home until it reaches your desired temperature. Central air systems pull hot air from your home, work to cool it down by releasing its heat outside, then distribute the newly-cooled air through a system of ducts in your home. That way, every room is reaching the ideal temperature.

Learn more specifics about how your air conditioner works.

How does ductless air conditioning work?

Ductless air conditioners work to cool just one room at a time. Unlike central air conditioning, which cools your entire home via a system of ducts, ductless air conditioning directly releases cool air into a single room.

Ductless systems require one outdoor unit and at least one indoor unit. If you want to cool more than just one room but still use ductless air conditioning, you can install up to five indoor units that will all work at the same time together with the singular outdoor unit.

Does an air conditioner take in air from the outside?

No. Air conditioners take heat and humidity out of the air inside your home, then distribute that heat and humidity outside while returning the newly cooled air back to the house. Air conditioners never take air from outside and put it in your home. Instead, they work by cooling down the air that’s already in your home.

Can an air conditioner improve indoor air quality?

Yes, air conditioners can improve air quality. After heat and humidity are absorbed from the air inside your home, the air is filtered for dust, lint, and debris. The heat gets moved outside, but the air that remains and goes back into your home is cleaner than before, resulting in better air quality.

Can I just turn on my air conditioner after winter is over?

After several months of inactivity, your air conditioner will need a little attention before the cooling season kicks into gear. Here are five things to do before turning on the AC after winter. Make sure your AC is ready for the summer heat with these helpful tips.

How to prepare your AC for the summer heat?

The overbearing summer heat is coming, which means that your AC unit will be putting in overtime for the next couple of months to keep your home cool. This tall request requires your system to be in top working order, meaning you should get a routine check-up of the entire unit to ensure everything is working correctly before the brutality of summer catches up with AC maintenance. Luckily, Service Legends has all the tips you need to set your HVAC system up for success!

Learn how to keep your AC running smoothly all summer long.

How to prevent AC copper theft?

Stealing copper is a risky business, mostly because it’s illegal (obviously) but also because it’s very dangerous.  Removing copper wiring or refrigerant tubing can lead to serious shocks or freezer burns from spraying coolant.  That’s why every obstacle between a potential thief and your air compressor is another less-likely theft.

Protect your system with these tips.

Can a boxed fan keep you cool?

Most definitely! A box fan is a great way to save on utilities during the summer with home ventilation. Box fans are an inexpensive and easy way to keep the house cool and maintain a healthy IAQ (indoor air quality) throughout the season.

Window fans are a valid alternative for people who live in climates that experience mild summers, unfortunately, they are not compatible with our heat (and often high humidity). But box fans can be used in the same way, for the same effect, and also offer a versatility that the stationary window fans can’t afford. If you are thinking about trying out some box fans for alternative cooling, we’ve compiled a few essential tips for maximizing their value.

Geothermal FAQs

How does geothermal heating and cooling work?

A geothermal system operates like a standard air conditioning system in that it transfers heat, but does it more efficiently by transferring the heat to the ground through interconnecting loops.

To put it simply, geothermal is a great way to heat or cool a structure using the existing ground temperature. In the summer, the system removes the heat from your home and dumps it into the earth. In the winter, it extracts the sun’s energy from the ground and pumps it into your home providing the perfect comfort but in a very efficient manner. 

Geothermal heat pumps can do all sorts of things—from heating and cooling homes to warming swimming pools. These systems transfer heat by pumping water or a refrigerant (a special type of fluid) through pipes just below the Earth’s surface, where the temperature is a constant 50 to 60°F.

During the winter, the water or refrigerant absorbs warmth from the Earth, and the pump brings this heat to the building above. In the summer, some heat pumps can run in reverse and help cool buildings.

What is a geothermal heat pump?

Heat pumps provide winter heating by extracting heat from a source and transferring it into a building. Heat can be extracted from any source, no matter how cold, but a warmer source allows higher efficiency. A ground source heat pump uses the top layer of the earth’s crust as a source of heat, thus taking advantage of its seasonally moderated temperature.

In the summer, the process can be reversed so the heat pump extracts heat from the building and transfers it to the ground. Transferring heat to a cooler space takes less energy, so the cooling efficiency of the heat pump gains benefits from the lower ground temperature.

Ground source heat pumps employ a heat exchanger in contact with the ground or groundwater to extract or dissipate heat. This component accounts for anywhere from a fifth to half of the total system cost and would be the most cumbersome part to repair or replace.

Correctly sizing this component is necessary to assure long-term performance: the energy efficiency of the system improves with roughly 4% for every degree Celsius that is won through correct sizing, and the underground temperature balance must be maintained through proper design of the whole system. Incorrect design can result in the system freezing after a number of years or very inefficient system performance; thus accurate system design is critical to a successful system.

How is a geothermal system installed?

Geothermal works with a series of pipes transfers energy from the ground and these pipes can be buried in the ground, sunk in a pond, or even by using an existing well.

 “Closed loops” use re-circulated fluid in a series of pipes installed vertically, horizontally, or in a pond. “Open loops” use well water.

Running the pipes vertically is a great choice for limited land space but horizontal loop systems can go in a variety of locations and work just as well at a reduced installation cost. Our experts at Service Legends can survey the site location and help determine the ideal location for your system.

How deep are geothermal ground loops buried?

In Iowa, geothermal ground loops are buried just below the frost line – typically about 6-10 feet deep.

Will an underground loop for installing geothermal effect my lawn or landscaping?

No. Research has shown that loops have no adverse effects on grass, trees, or shrubs. Most horizontal installations require trenches about six inches wide. Temporary bare areas can be restored with grass seed or sod. Vertical loops require little space and do not damage lawns significantly.

My yard contains many shade trees. Will this affect ground temperature and my ability to use it as an energy source?

Not at all. The geothermal system is installed deep enough that it utilizes constant ground temperature.

Will my existing ductwork function with a geothermal system?

Yes, in most cases. Your home comfort advisor will be able to go over this with you during your free estimate.

Learn more about the basics of how geothermal works.

Will I have to add insulation to my home if I install one of these systems?

Ground source heat pump systems will reduce your heating and cooling costs regardless of how well your home is insulated. However, insulating and weatherizing are key factors in gaining the maximum amount of savings from any type of heating and cooling system.

Why is geothermal the right choice for me?

The average home’s cost for cooling, heating, and hot water is about 70% of your utility bill. By going green with a Geothermal system, you can put more green in your pocket.

Since our heating season in Iowa is so long (approximately 5 months out of the year), the geothermal system efficiencies can make a big impact on your energy costs throughout the winter. The temperatures underground vary little from summer to winter, making a geothermal system a good choice in our climate. In the summer, the lower operating costs of geothermal systems make cool temperatures and dry air a budget-friendly reality.

Check out seven reasons geothermal is right for you.

How much money can a geothermal system save me?

A geothermal system can typically save 25-50% versus traditional heating sources.

What is a ductless mini-split system?

A ductless mini-split system is an alternative to traditional heating and cooling like central air. Ductless HVAC works similarly to central heating and cooling, except that it doesn’t require ductwork. Your mini-split system will have an indoor and outdoor unit, but it will only require a small hole to be cut through the exterior wall—just big enough for a tube of refrigerant to pass through. Inside your home, the air will be conditioned and returned into the room by the same unit.

Learn more about ductless mini-splits.

How does a ductless heat pump work?

Many people use ductless mini-split systems for cooling, but we usually recommend installing heat pump systems, so they can be used for both heating and cooling. This can help improve your overall energy efficiency! A ductless heat pump is an efficient zonal heating and cooling system that doesn’t require ducts. It comprises just an outdoor compressor unit and one or more indoor air handling units, linked by a refrigerant line.

What are the benefits of HVAC zoning?

Zoned HVAC system allows for better comfort control, decreased energy bills, and higher energy efficiency (energy waste is reduced because your HVAC equipment won’t have to work as hard to regulate the temperature throughout the house).

Learn more about zoned HVAC.

Should I cover my air conditioner or heat pump in the fall and winter?

Covering the unit is not necessary, especially if you have a heat pump that runs all year long. In fact, covering an entire unit may actually trap moisture and may cause more problems than you realize.

Can an updated HVAC unit increase the value of my home?

The short answer: yes! At Service Legends, we want you to be as informed as possible on how to get the most value from your home’s HVAC investment. Here’s what you can expect when getting your home comfort system replaced with Service Legends.

Read how an updated HVAC unit impacts your home’s value.

How long is my central heating and cooling system expected to last?

According to energy.gov, the average lifespan of your central HVAC system is between 15 and 20 years. This assumes, however, that you support your equipment with regularly scheduled maintenance. We’ve found that systems without regular maintenance last between 8 and 10 years, while systems with proper maintenance last between 20 and 25 years.

This also assumes that your heating and cooling equipment has been installed properly. Besides regular maintenance, proper installation is the most important factor when estimating your system’s “lifespan.”

According to energystar.gov, over half of all new HVAC systems do not live up to rated efficiency levels. This not only negatively affects your utility bill but also reduces the lifespan of your unit. “In fact, improper installation can reduce performance by as much as 30%.

Should I have my HVAC system inspected prior to buying a new home?

The short answer: yes! At Service Legends, we want you to be as informed as possible on how to get the most value from your home’s HVAC investment. Here’s why you should always have a qualified technician inspect the HVAC system before buying a new home.

Is it okay to close off HVAC vents?

Most registers that blow conditioned air into the home are installed with some sort of lever that allows you to open or close it. This must mean that it is ok, maybe even recommended that you use it, right? Wrong!

Learn why it is not a good idea.

Plumbing FAQs

Is my water heater gas or electric?

Simply remove the access panel on the side of the water heater and look inside for a blue flame. This is called a pilot light and indicates the presence of natural gas. If you see a pilot light, you most likely have a gas water heater. Electrical water heaters do not have pilot lights.

Look at the top of the heater for an electrical supply cord. This looks like a thick extension cord and is generally black or gray. If you see one going into the top or side of the heater, it is an electric water heater.

How do I unclog a toilet?

The easiest way to unclog your toilet is with a plunger, but if you don’t have one on hand, follow these easy-to-follow instructions:

  1. Fill the toilet with dish soap or laundry detergent
  2. Add a pot of boiling water and then wait a few minutes before flushing

The hot water should break through the clog as the soap washes everything through the siphon and out of the drain. If your toilet doesn’t unclog, give Service Legends a call to fix your toilet.

Why is my toilet always running?

A running toilet is usually caused by a bad toilet flapper, the rubber or plastic valve on the bottom of your tank, that fails to seal. Follow these simple steps:

  1. Open the toilet tank and adjust the float arm to see if the water stops an inch below the overflow pipe.
  2. If the water doesn’t continue to fill, the toilet flapper needs replacing.

Give Service Legends a call today to replace your toilet flapper.

How do I replace my toilet flange?

My water bill went up. How do I check for water leaks?

The main causes of high water bills are running toilets, which can waste up to 200 gallons per day, and leaky faucets, which can drip up to 20 gallons per day.

Check for water leaks by inspecting faucets, as well as removing your toilet bowl’s tank and listening for any sounds, like hissing.

If you don’t find leaks in either of those locations, you’ll need to check your water line and hose bibs. You may also want to contact a plumber at Service Legends located in Des Moines, IA.

What do I do if my toilet leaks at the base?

If your toilet is leaking at the base, make sure to tighten the t-bolts and replace the wax ring if your toilet leaks at the base.

Give Service Legends a call if you need help.

Why does my toilet smell every time I flush it?

Your toilet may smell when you flush because of a broken airtight seal. Sewer gas is blocked from entering homes by the drain venting system.

A U–shape in the pipe holds a designated amount of water after each flush. The water acts as an airtight seal to block sewage gases. If too much negative pressure occurs, however, the water level can lower and break the seal, causing a smell after you flush.

Service Legends can help solve this problem – give us a call.

Do I actually need maintenance on my plumbing?

Maintenance on your plumbing is necessary whenever a faucet leak persists or drain blockage occurs. A clogged toilet, or toilet that continues to run, as well as low water pressure also mandates service, especially when do-it-yourself (DIY) home repairs fail to fix the problem.

How do I clean a dishwasher?

Clean your dishwasher by filling the detergent container with white vinegar and running the machine on a long, hot cycle. Do not leave any dishes in the washer for this cleaning cycle.

Learn how to clean a dishwasher with vinegar and baking soda in the following step-by-step guide.

Why is my dishwasher not draining?

If your dishwasher isn’t draining, it’s likely due to a leaky inlet valve or mineral deposits in the pipes. Follow these steps:

  1. Empty the dishwasher and start a new cycle on empty.
  2. Cancel the cycle after a few seconds and open the door.
  3. If the water is gone, the dishwasher is fine. If not, the inlet valve should be replaced.

Contact the Service Legends team of Home Comfort Heroes to replace your inlet valve.

How can I prevent frozen pipes?

You can prevent frozen pipes during the coldest times of the year by allowing sink faucets to slightly drip non–stop, especially if you’re away from home for several days.

Get a plumbing evaluation if you’re not 100% sure. We’re here to help!

What do I do if my water meter is leaking?

If your water meter is leaking, call a plumber at Service Legends immediately. You should also contact your water utility provider as well because if the leak is between the meter leading to the water utility, it is their financial responsibility to fix the water leak. Leaks between the meter and your home are your responsibility.

Why did our outdoor faucet stop working all of a sudden?

Outdoor faucets tend to stop working suddenly due to debris in the faucet’s opening or obstruction with the aerator or inner spout.

Give Service Legends plumbers a call to diagnose and repair your outdoor faucet.

Why does my outdoor faucet keep running or dripping?

Your outside faucet is likely running or dripping because the gasket or the valve seat has worn out and needs to be replaced.

Give Service Legends plumbers a call to diagnose and repair your outdoor faucet.

How do I know if my sump pump is working?

If you already have a sump pump installed for your house, make sure that it is prepped for potential floodwaters and make sure it’s working properly. There are a few basic steps you can take to see that the sump pump is in good shape. 

  1. Pour water into the sump (the water collection pit); 5 gallons is a good amount. The pump should automatically turn on.
  2. Wait for the pump to remove the water and shut itself off. Then pour in more water to see if the pump will turn back on and off. If the pump fails to come on in either test, schedule repairs for it right away.
  3. After testing the sump pump, check around the sump to see if there is any debris that may be sucked up into the pump as it operates. Remove as much as possible. Then clean out the weep hole of the pump, which is a hole located between the pump and the check valve. Use a toothpick or cotton swab to see that it’s clear.

If you’ve had your sump pump for a few years already, we recommend scheduling complete professional maintenance for it, even if it seems as if it’s working fine. This precaution ensures that any minor problem is caught before it can become a major problem.

Is it worth it to replace my sump pump?

If you’re wondering whether your home even needs a sump pump, consider whether you’ve struggled with flooding issues in the past. If your house is in a flood-prone area, your yard has poor drainage, or you’ve dealt with any other water problems, then it’s likely well worth it to replace your old sump pump with a new one.

How long do sump pumps normally last?

Most sump pumps have a lifespan of 10 years. If you’re unsure of how old your pump is (but you suspect it may be on its last legs), have Service Legends inspect and clean the pump.

Will my pump work if the power is out?

Most sump pumps require electrical power to operate. There are devices with a Battery Backup Unit that will operate a secondary pump using battery power. This is helpful for homes that frequently lose power or have high water.

Can I use a sump pump with an extension cord?

We strongly recommend that you do NOT use an extension cord. It is better to plug the sump pump into a dedicated outlet that is fed by a circuit breaker or fuse that feeds power only to that outlet. This ensures that the pump will receive proper voltage. If there is no outlet near the sump pit, we recommend you have one installed by a professional electrician.

Is it okay to drain my water softener or laundry water into my sump basin?

It is NOT recommended to drain laundry or water softeners into a sump basin. The chemicals and debris from these appliances can cause damage to the pump, decreasing its lifespan. The discharged water may also cause a buildup of debris on the float switch, causing it to work improperly. Sump pumps are designed to be used with clear, clean groundwater.

What’s a check valve and do I need one?

Yes. A check valve is a one-way valve. It is installed in the discharge pipe of your sump pump. When the pump runs, the water is forced out through the pipe and valve. When the pump stops running, the water will not be able to flow by gravity back into the basin, staying above the check valve. This prevents the pump from having to re-pump the water, increasing the life of the pump.

What kind of water softener salt should I use?

We recommend using 99% salt crystals for your water softener. You can find this salt at your local grocery store, hardware store or gas station.

How can I find the manufacture date on my water softening tank?

The manufacturing date and serial numbers should be located on your tank’s label. They are located below the model number.

Why does my water softener fail to regenerate?

The following is a list of common reasons why your water softener may fail to regenerate:

  • The unit is unplugged or no power is going to the unit.
  • The unit is in bypass mode.
  • The meter is counting gallons remaining off of the timer.

Why doesn’t my water feel slippery when washing dishes anymore?

Your water may not feel slippery because your water softener may not be re-generating properly. Another reason may be that there is no salt in your brine tank.

Is my water softener using too much salt?

You can tell if your water softener is using too much salt by verifying that your capacity, hardness, meter setting and salt dosage are set correctly for the size of your system.

Next, check if your brine tank is full of water.

  • If it is, push the float down and see if the brine tanks starts to fill.
  • If it is not, check if your brine valve refill amount is correct.

If you’re not sure, give Service Legends a call and our experienced plumbing technicians can make sure your water softener system is set up correctly.

Why is the water pressure in my home low?

To determine the potential cause of low water pressure, put your water softener in bypass mode and see if the pressure increases.

  • If the pressure does not increase, then the restriction is in your plumbing. Check all shut-off valves.
  • If the pressure increases, the pressure drop is within the water softener system. You may need to replace your resin.
  • If the issue persists, contact Service Legends for further assistance.

Why are my drains plugged with resin?

Check that the inlet and outlet plumbing on your water softener is not reversed. If your inlet and outlet are plumbed correctly, your distributor assembly is likely cracked and needs to be replaced. Contact Service Legends for further assistance.

Will installing a softening system restrict the water flow or pressure in the house?

Yes, the water has to flow through the unit and the resin. These cavities will create a pressure drop. Based on the size of the system and at what flow rate will determine how much pressure drop there will be.

How do I stop my plumbing pipes from knocking?

Loud noises coming from plumbing pipes could be a sign of a serious problem. Here are the top three causes of banging plumbing pipe sounds: Water hammer, expanding/contracting copper pipes, and water pressure that is too high. Knocking sounds are often heard after a water supply is shut off, while the water is running or randomly throughout the day or night.

Learn more about how to stop these noises from occurring and where to troubleshoot the source of the problem.

Electrical FAQs

When should I call an electrician?

Make sure to call a qualified electrician in the following scenarios:

  • When you are resetting circuit breakers or changing fuses too often.
  • When you turn on your air conditioner and the lights dim in the room.
  • When your lights flicker or go on and off. When you can smell electricity burning.
  • When you have six electronic devices going into one outlet in back of your electronics center.
  • When you have receptacle outlets overburdened by multi-plug strips.
  • When a three-prong plug needs a two-prong adapter.
  • If you have to run extension cords to plug in electrical devices.

Can electricians install ceiling fans?

If you need a ceiling fan installed, a certified electrician at Service Legends can and is licensed to do the task. An electrician should be the first person you call if you need a ceiling fan installed, as long as they’re both certified and insured.

To install a ceiling fan, an electrician will need to stand on a ladder, work with the electrical system, and possibly venture into an attic. There’s a risk of injury to these tasks, so you want to hire someone who knows what they’re doing.

Learn more.

Can you change a light fixture without turning off a breaker?

There’s nothing like a new light fixture, but rushing the process will only lead to more problems. You should always turn off the breaker to the light fixture and test that everything is safe with a voltage tester.

What does electrical maintenance include?

Regular home electrical maintenance is critical to keep things running smoothly and safely. You take your car in to get serviced regularly and you go on well visits to the doctor (if you don’t, you definitely should). We schedule these things as preventative maintenance so that we can keep our cars and ourselves running properly for as long as we can. Why would you not do the same for your home’s electrical system?

Read more about why you should keep up with your home electrical maintenance.

What's the difference between a three-pronged plug and a two-pronged plug?

The third prong on a plug is a grounding prong. Two-prong receptacles do not have the same level of grounding as a three-prong device. The third grounding prong provides additional protection to the electrical system, the item plugged in, and you from electrical shock.

What should I do if an appliance continuously blows a fuse?

First, make sure there are not too many appliances plugged into one circuit, as this can overload it. If it’s just one appliance, unplug it and either replace it or call us to repair it. You could also try connecting another appliance to the problematic receptacle. If it still shows signs of trouble, have the receptacle and or the circuit checked by our home electrical service experts at Service Legends.

What's the benefit of whole-house surge protection?

Whole-home surge protectors control surges directly where your home’s power is distributed: your breaker panel. Large appliances and systems that can cause surges, your air conditioning unit, and power generators, each have a dedicated circuit on your breaker panel. When they send surges back to the panel, they are distributed to other electronics in your home. A whole-home surge protector monitors these surges and diverts excess power into the grounding wire while allowing normal voltage levels to safely continue powering your electronics.

With whole-home surge protection in place, light bulbs and electronics will last longer because they will no longer receive surges from larger appliances. Not only will you save money, but you can also feel better about your television, computer, and mobile devices being safe from large power surges.

What causes electrical power surges?

Typically when people think power surges, they picture a lightning strike causing a black-out and ruining their television. Lightning can cause a power surge, but the truth is that 80% of power surges are generated inside your home. Generators and motors found in A/C units and appliances send surges into your electrical system on a daily basis. Sometimes these surges are small and simply wear down electronics and lights. But if multiple motors turn on at the same time, it can send an electrical surge through your home’s electrical system that’s large enough to permanently destroy electronics plugged into your outlets.

What's the difference between a blown fuse and a blown circuit breaker?

When the electrical current that passes through a fuse exceeds the limit, it burns a hole in the thin strip of metal. This stops the flow of current and it means you have blown a fuse. Fuses need to be replaced (not reset).

When the electrical current exceeds the limit through a circuit breaker, however, the breaker trip setting opens to stop the flow of current. Breakers are re-settable by flipping the handle on the face of the breaker.

Are LED lights better than incandescent?

LED lights are more expensive to purchase than incandescent lights, but they’re more efficient (they’ll last 50,000 hours instead of 1,200 hours). They also have a lower annual operating cost, which is great for people trying to go green.

Do I need a special electrical box to install a ceiling fan?

Yes. Because a ceiling fan is an active load that is heavier than most light fixtures, you need a special mounting box designed for this application. Saddle boxes are usually good for fans up to 35 pounds.

What are low voltage fixtures?

Low-voltage fixtures include a transformer to reduce voltage (say from 120 volts to 12 volts). The downside to low-voltage fixtures, however, can be higher installation costs. Also, transformers tend to create heat and mounting locations can be tricky.

What does grounding mean?

When you use an electrical appliance, the current flows from your service panel to the device. A grounded wire gives the unused electrical current a safe way back to the service panel so there’s no danger in the event of a short circuit.

What is a GFCI?

You may have seen an electrical outlet with a “test” and “reset” button in the middle – this is a GFCI (ground fault circuit interrupter). It automatically shuts off an electrical circuit when it detects that the current isn’t flowing correctly. It’s also used to reduce the risk of electrical shock from a receptacle located in damp locations and/or countertop areas.

What is an AFCI?

Starting January 1, 2002, The National Electrical Code, Section 210-12, requires that all branch circuits supplying 125V, single phase, 15- and 20-ampere outlets installed in dwelling unit bedrooms be protected by an arc-fault circuit interrupter. Eventually they will be in more areas but the NEC selected to require them on bedroom circuits first because a CPSC study showed many home fire deaths were related to bedroom circuits.

The AFCI (Arc Fault Circuit Interrupter) breaker, will shut off a circuit in a fraction of a second if arcing develops. The current inside of an arc is not always high enough to trip a regular breaker. You must have noticed a cut or worn piece of a cord or a loose connection in a junction box or receptacle arcing and burnt without tripping the regular breaker. As you can guess this is a major cause of fires in a dwelling.

There is a difference between AFCIs and GFCIs. AFCIs are intended to reduce the likelihood of fire caused by electrical arcing faults; whereas, GFCIs are personnel protection intended to reduce the likelihood of electric shock hazards. Don’t misunderstand, GFCIs are still needed and save a lot of lives.

Combination devices that include both AFCI and GFCI protection in one unit will become available soon. AFCIs can be installed in any 15- or 20-ampere branch circuit in homes today and are currently available as circuit breakers with built-in AFCI features. In the near future, other types of devices with AFCI protection will be available.

If a GFCI receptacle is installed on the load side of an AFCI it is possible for both the AFCI and the GFCI to trip on a fault if the current exceeds the limit for both devices. It is also possible for the AFCI to trip and the GFCI to not trip since the two devices could race each other. However, in no case is safety compromised.

What does a fishy smell coming from my outlet mean?

If you notice a smell coming from your outlet or switch, there’s a good chance your receptacle could be damaged. Turn off the power immediately and call our home electrical service experts.

Indoor Air Quality FAQs

What is indoor air quality?

“Indoor air quality,” or IAQ, is a relatively new topic in environmental safety. While a lot of attention has been placed on outdoor pollution over the past few decades, the focus on indoor air quality is just beginning.

The quality of a home’s air mainly has to do with the number of pollutants inside, but it’s also determined by humidity and ventilation levels. The U.S. Environmental Protection Agency has found that concentrations of pollutants can be up to 100 times higher indoors than outdoors. The American Lung Association estimates that most people spend 90% of their time indoors, so clean indoor air is very important.

How important is my indoor air quality?

The short answer? So important! Your indoor air quality can be as much as 100 times worse than the outdoor air. That means pollutants, allergens, dust, and mildew can be circulating in your home affecting your family’s health and wellbeing. Improving and maintaining your indoor air quality is vitally important to your home and family.

Learn more indoor air quality facts.

What causes indoor air pollution?

According to the U.S. Environmental Protection Agency, items inside the home that release gas are the primary cause of indoor air problems. The list includes carpeting, upholstered furniture, gas appliances, paints and solvents, cleaning products, air fresheners, dry-cleaned clothing and pesticides. If you have an attached garage, fumes from the gasoline, oil and antifreeze in your car can find their way into your home’s air. Harsh chemicals can also come from cigarette smoke and wood stoves.

Insufficient ventilation can worsen the problem because pollutants get trapped inside. Tightly sealed and well-insulated homes keep out fresher outdoor air, which can dilute the pollutants. High temperature and humidity levels can also increase concentrations of some pollutants.

What are the benefits of installing a whole-house humidifier?

With central heating, people are confined indoors with unnaturally dry air for many months each year. Humidifiers help to keep comfortable levels of moisture in the air, which is essential for your respiratory health.

Whole-house humidifiers work like old-fashioned room humidifiers: They put moisture into the air, making harsh, dry air easier to breathe. A major difference is that they improve the air in every room of your home—no more carrying a humidifier from room to room in the winter.

How do I know which humidifier is right for me?

There are a few factors you should take into consideration when purchasing a humidifier for your home:

Size – A humidifier’s capacity, or the amount of moisture it can dispense in a given time, should match your particular household’s needs. The capacity is measured as gallons per day of operation. One method that is used to determine the correct-size humidifier for your home is multiplying the total floor area in square feet by the ceiling height.

Cost – Consider not only the purchase price of the unit. but also the operating and maintenance costs. Some products consume more energy than others, so choosing a model that is right for your home and budget is extremely important.

Type – Service Legends offers a variety of whole-home humidifiers—including Steam, Bypass or Power— to help maintain proper moisture levels. Our Healthy Climate® Steam Humidifier is the optimum solution. It heats water to produce steam, dispersing it evenly throughout your home to make the air more comfortable. All the while, it operates efficiently, using nearly all the water it takes in.

Regular maintenance is necessary to keep your humidifier in top working condition.

Why is my throat so dry?

During extremely cold weather, your home loses moisture to the outdoors, and the humidity level may drop to as low as 10 percent. A humidifier adds moisture to your indoor air and can help relieve ailments related to dry respiratory membranes.

One of the major causes of respiratory infections is inadequate humidity during cold weather. The start of the heating season each fall causes many people to begin having repeated attacks of winter colds. Winter weather is blamed for these problems, but the actual cause may be dryness, which develops in the membranes of the nose, throat and bronchial tubes. Relative humidity also has a significant effect on controlling the occurrence of airborne infections.

How does a germicidal light work?

Easily installed inside your ductwork, these solutions emit powerful rays of ultraviolet light that penetrate the cell walls of biological contaminants on surfaces, damaging their physiological structure so they can no longer grow, multiply and spread throughout your home. Even when your heating and cooling system isn’t running, germicidal lights work continuously.

Learn more about UV lights.

What causes low humidity levels in a house?

Indoor air tends to get dry when there are low humidity levels outside. Combined with cooler weather, heaters can also dry out the air inside your house.

Learn why whole-home humidification matters.

How can I remove odors?

You may have tried to get rid of odors in your home by spraying air fresheners or lighting candles. The problem with these methods is that they only mask the odors—they don’t get rid of them. In fact, the chemical ingredients in the mist they produce may further contaminate your home. You can clean your indoor air with houseplants.

Discover an easy way to remove odors and improve your indoor air quality at the same time.

Is duct cleaning a waste of time?

Duct cleaning is not a waste of time! Here are some ways you can tell if you need a professional duct cleaning:

  1. If someone in your house is suffering from frequent allergy attacks from the amount of dust in your home
  2. If you see cobwebs, hair, or other bits of dust and debris blowing out of your registers
  3. If there is visible mold inside and around the edge of your ducts
  4. If you suspect animal infestation or nesting in your ducts
  5. If you have recently done extensive remodeling in your home. Ducts should be covered during any home remodeling.
  6. If you look into your duct with a flashlight and see dust bunnies, objects, dirt, and debris.
  7. You don’t remember the last time your ducts were thoroughly cleaned
  8. Strange noise in the duct work

Which Way Does Furnace Air Flow?

Forced air furnaces recirculate air through a home: pushing air (cool or heated) in, and pulling spent air back in for another cycle. So air flows from your ducts, through the filter, and into the furnace.

What’s The Right Furnace Filter Direction?

If you are looking at a furnace filter, find the arrow that indicates the proper airflow direction. That arrow must always face toward the furnace and away from the return duct that carries the air in need of heating or cooling.

How Do I Install A Furnace Filter?

This is pretty easy once you’ve found the arrow mentioned above and inserted it with the arrow facing towards the furnace and away from the return duct. Need more help? Give Service Legends a call and we can help.

What Do Furnace Filter Ratings Mean?

All filters are rated using the Minimum Efficiency Reporting Value, or MERV, scale which goes from 1 to 20. The United States Environmental Protection Agency recommends air furnace filters with a MERV between 7 and 13 for most homes. Check out this chart to see exactly what the ratings mean: MERV Rating Chart and see below for more details on selecting the right filter for you.

What Are The Best Furnace Filters?

What’s the best furnace filter? Well, that all depends on how much you want to spend and what you’re trying to filter.

You need to be aware of the MERV scale (explained above). A furnace filter with a high rating can slow airflow too much, but a low-efficiency filter won’t filter dust very well. When selecting the filter, it’s important to strike the right balance and ALWAYS consult your furnace manual to see the manufacturer’s specifications.

For most homeowners, a MERV 7 or 8 pleated filter provides a good balance between cost and filtration efficiency. These filters trap 80 to 95 percent of the particles 5 microns and larger—more than enough for most homes. However, if you have family members with allergies or an impaired immune system, you may want to invest in a MERV 11 or higher filter. But be warned, you must change these filters regularly to protect your furnace.

How Do I Know If My Furnace Filter is Dirty and Needs Replacing?

There are a few different ways of checking whether the filter is dirty and needs to be replaced:

  1. Examine your furnace filter carefully for the buildup of dirt, dust and other contaminants. A large buildup can be a sign that it’s time to replace your filter.
  2. Listen to the sound of air moving through your furnace. If you remove the filter and there is a significant release of air pressure, this means the buildup of dust and dirt has reduced the effectiveness of the filter. It should be replaced.
  3. Keep an eye on the amount of dust and dirt building up in your home over a set period. If you notice an increase in the amount of dust and dirt on furniture and other household items, it may be time to change the filter.
  4. The easiest and most reliable way of telling whether your filter is dirty and needs to be replaced is installing a filter monitoring system like FilterScan Wifi. This provides automatic monitoring of your filter system and alerts you when it’s time for a replacement. Using FilterScan Wifi means you won’t ever miss changing the filter when it’s necessary to avoid damage or low air quality, nor will you waste money on changing a filter that is still working effectively.

Insulation FAQs

How does home insulation work?

Insulation works by resisting the flow of heat. Heat is a form of energy and always seeks a cooler area—in your home this means it flows outward in winter, and inward in summer. Insulation slows this heat flow, so your heating and cooling system requires less operation to maintain your desired temperature, which saves you money. Home insulation is one of the most cost-effective ways of conserving energy, saving money on heating and cooling bills, and making your home more comfortable.

How much money can insulation save you?

It’s difficult to determine exactly how much insulation can save based on a universal scale, but homeowners can save a lot of money each year by installing insulation! Re-insulating is a good way to help maximize your home’s energy efficiency. Specifics about how much energy you can save with insulation depend on where you live, the size of your house and more.

Check out these five home maintenance tips.

What does R-value mean?

Insulation’s ability to resist heat flow is identified and labeled by R-value, “R” meaning resistance to heat flow. The higher the R-value, the greater the insulating power.

How much insulation should I have installed?

The amount of insulation recommended for your home will vary depending on a number of factors:

Where you live—Different climates require different insulation R-values. You will need a higher R-value of insulation if you live in Northern areas of the country than if you live in the Southern regions.

Your home’s age—If your home is more than 10 years old, you likely need more insulation.

Will I get a return on an attic insulation investment?

In January of 2016, Remodeler Magazine released its annual “Cost vs. Value” report, which breaks down both the cost and return on investment of many of the most common home improvement options.

Adding fiberglass attic insulation was included in the report for the first time, and it topped the list in terms of the percentage of your initial investment you would recoup in the form of increased home value at 117%. This figure only speaks to what it does to your home’s value, it does not even take into account any possible energy bill savings*. The results of this survey demonstrate that re-insulating to your home can improve its value.

*Savings vary. Higher R-values mean greater insulating power.

Learn small ways to save big on energy bills.

How much will I save by adding insulation to the walls, ceilings, and floors of my home?

Insulation saves money, increases home comfort, and protects the environment by reducing energy use.

According to the U.S. Department of Energy (DOE), the typical U.S. family spends close to $1,500 each year on energy bills. DOE statistics show that, typically, 44% of a homeowner’s utility bill goes for heating and cooling costs. DOE states that homeowners may be able to reduce their energy bills from 10% to 50% by taking certain steps. One of the major steps is increasing the amount of thermal insulation in their existing homes or purchasing additional insulation when buying new homes.

Unless your home was constructed with special attention to energy efficiency, adding insulation will probably reduce your utility bills. The amount of energy you conserve will depend on several factors: your local climate; the size, shape, and construction of your house; the living habits of your family; the type and efficiency of the heating and cooling systems; and the fuel you use. Energy conserved is money saved, and the annual savings increase when utility rates go up. Insulation upgrades also add to the value of your home.
