How to reduce the strain on your overworked furnace during frigid weather

By  | 

FLINT (WJRT) (12/28/17) The cold weather has been taking a toll on Mid-Michigan furnaces.

Record breaking cold temperatures across the region this week have been hard on our furnaces.

"The strain's going to be there regardless of the cold temps. I would suggest everybody check their air filters, make sure those things are clean so you can move proper air through the furnace," said Mike Anson of Goyette Mechanical. "You'll find you can probably save a couple of degrees on you thermostat just by adding the proper humidity."

A dirty furnace filter can shut your furnace down. If you're not moving the proper air through the furnace it's going to overheat the furnace and cause it to short cycle. You may even find yourself without heat.

"If the batteries start to die in the thermostat it could either run non-stop. It could not run at all," Anson said.

A faulty furnace can spill carbon monoxide into your home. Carbon monoxide is a colorless, odorless gas that can be fatal if inhaled.

Carbon monoxide detectors are advised in every home near the furnace and around living and sleeping areas. Some fire departments offer them free or they can be purchased for around $25 at most home improvement stores.
