Saving The Planet, One Geothermal System At A Time

With an increase in high-tech solutions and more tax credits for homeowners, geothermal is becoming increasingly popular. The temperature underneath your home can range between 40-50 degrees which is stable enough to draw heat or cooling year-round. While the initial cost of a geothermal system can be high, it will last for more than 50 years and the operating costs are incredibly affordable, especially as fuel costs continue to rise.

Did You Know?

Heating and cooling your home with geothermal is the equivalent of planting 750 trees or removing 2 cars from the road FOREVER…and it’s now available for our residential customers in Des Moines, IA metro area.

How We’re Different From Our Competitors

Don’t trust an amateur to install, maintain, or replace your geothermal system. Refrigerant piping must be set up properly, with specific measurements of distances that the refrigerant has to travel and a correct size calculation for how much heating or cooling will be needed. We can also provide maintenance in a simple yearly inspection.

Before we replace your system, we run a heat load calculation to determine proper size, take measurements, and present you with the best options for everything: a new condenser, new ductwork, new condensate drain lines, and any other options such as zone systems, UV light disinfectors, air purifiers and anything that would apply to your home’s comfort system and air quality. 

We discuss your budget and look over rebate options, tax credits, energy efficiency, and of course, price, to find the ideal system for your home. And because a new home comfort system is one of the most expensive things most people pay for (next to a car and your home itself), we go over our financing options.

The Best Warranties & Guarantees

Frequently Asked Questions

Geothermal Q&A

How does geothermal heating and cooling work?

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 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 it installed?

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 below the frost line typically about 6-10 feet deep.

Will an underground loop affect 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 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.

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 choice for me?

The average home’s cost for cooling, heating, and hot water are about 70% of the 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, 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.

How much money can a geothermal system save me?

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