PITTSBURGH (NewsRadio 1020 KDKA) –  Cold enough for you? With temperatures in the single digits, and wind chill in negative numbers, this is by far the coldest we’ve seen in a while in this area.

It’s also the coldest weather your house has seen, and that puts a huge strain on your furnace. KDKA-AM’s Larry and John talk to Rocco Florio, owner of Air Pro Heating and Cooling in Pittsburgh, and he says this is the time of year that he gets calls for furnace issues that you can prevent.

“Keep your furnace filter clean,” says Florio. “The one inch filters, you should change every two months.”

The problem becomes that the filter clogs the air flow to the furnace, which causes a safety measure to keep the furnace from overheating. Then, the furnace just blows cold air.

“If that air doesn’t come through, you don’t get that cycle of moving hot air and cold air around your home.”

Florio has lots of other tips and tricks to keep your furnace in tip-top shape through the winter, and all year-long.
