4 Signs Your Furnace May Not Be Operating Efficiently

January 17, 2022

Your wintertime home comfort depends on a properly functioning furnace. A furnace that doesn’t operate as it should is more than a mere annoyance. It can affect your home’s heating capacity and create energy efficiency issues. Pay attention to signs such as inconsistent cycling and unusual sounds. They can indicate a problem with your furnace in in Forest Acres, SC.

Inconsistent Cycling

If your furnace is cycling on and off frequently, the air filter might be to blame. Changing the air filter regularly keeps the unit operating at peak efficiency. If the air filter isn’t the problem, the inconsistent cycling could be the result of a blower motor or thermostat issue. A system that constantly cycles on and off results in wasted energy and extra strain on its overall operation.

Unusual Sounds

Banging, rattling, clicking, groaning, and squealing are all abnormal sounds that shouldn’t be coming from your system. These noises could signal everything from worn motor bearings to loose belts and a cracked heat exchanger. Ignoring these sounds isn’t something you want to do. A small problem with a furnace part could turn into a more costly and serious problem to fix later.

Green, Red and Yellow Flames

If you have a gas furnace in your home, check the flame color on the burner. You should see a blue flame. If you find flames with green, red and yellow colors, turn off the unit and call us immediately. Abnormally colored flames could suggest a serious carbon monoxide leak from your unit.

Frequent Need for Repairs

Depending on the type of furnace you have, you can expect it to last between 10 and 20 years. If you’re continually having repairs performed on your old system, it might be time to consider a new one for your home.
