SALT LAKE CITY - In extreme cold temperatures, your furnace may be working extra hard to heat your home, but there are a few things that can help maximize its output.
Ryan Snow of Western Heating and Air Conditioning says furnaces often get dirty, which prevents them from working properly.
"The good thing to do is to have that tune up done every year," Snow said.
It's also important to have a backup source of heat in case the furnace breaks down, said.
The first step to maximizing air flow is to check your home's air filters and make sure they're clean. Check your windows, doors and duct work for cracks and holes.
