Heating repair technician inspecting a furnace in South Carolina

What a heat exchanger does

It separates the combustion gases from the air that blows into your home. When it cracks from years of heating and cooling cycles, those gases, including carbon monoxide, can mix with your air.

Warning signs

Soot around the furnace, a yellow flickering flame instead of blue, excess moisture on windows, a smell like exhaust, headaches or nausea that improve when you leave the house, and a CO detector alarm.

What to do

If a CO alarm sounds or you smell gas, leave the house and call the gas utility from outside. Then call us. If you simply have not had the furnace inspected in over a year, schedule a tune-up.

Prevention

An annual furnace inspection includes a heat exchanger check and combustion analysis. Install CO detectors on every level near the bedrooms and replace them every 7 years.
