Common Furnace Issues To Watch Out For


There’s nothing worse than waking up to a freezing home during the winter and needing to call for an emergency repair service that may not be available right away and comes with a hefty price tag. However, with proper furnace maintenance and knowing what signs to look out for, you can be aware of any furnace issues that may be causing it to run inefficiently or damage your system.

Some common furnace issues include:

1. Clogged Filters

A clogged filter can cause your unit to use more energy to perform at the same level. This will make your system inefficient and cause your energy bill to increase over time. An indicator of your filter being clogged is if it makes your house smell musty when your furnace is turned on instead of allowing clean, fresh air into your home. You may also notice your home quickly becoming dusty soon after it’s been cleaned. To keep your system running as smoothly as possible, it’s recommended that you switch out your filters every three months.

2. Frequent Cycling

Short cycling is when your furnace or air conditioner turns on and off frequently. Instead of pushing out hot air when cool air has entered your home and matching what the thermostat is set to, the system will run on and off repeatedly. This often happens if your system is in need of maintenance or repair. Over time, it can cause significant damage to the equipment, lead to high energy bills, and create an uneven room temperature. Luckily, an HVAC professional will be able to quickly determine the problem and prevent further problems later on.

3. Strange Noises

Are you hearing rattling or popping noises coming from your furnace? Rattling could be caused by loose panels while the popping noises could be coming from heating ducts expanding and contracting. An HVAC professional will be able to determine the cause of the noises and tighten any loose panels or repair holes in your ducts.

4. Cracked Heat Exchanger

A heat exchanger is a device that transfers heat from one medium to another. It’s the component that separates the warming flame from the air and keeps your furnace running safely. However, if the heat exchanger is cracked, it can cause serious damage to your home and your health as it may cause carbon monoxide, sulfur dioxide, or nitrous oxide to leak into your home. Signs of a cracked heat exchanger include strange smells, soot build-up, and the presence of carbon monoxide.

5. Faulty Thermostat

If you find yourself constantly adjusting your thermostat without much change in the indoor temperature, an HVAC technician should come look at your unit to determine if your thermostat is faulty or if your furnace can no longer keep up with demands.
