LEXINGTON, Ky. (FOX 56) — With cold temperatures hitting central Kentucky, homeowners are starting to crank their heat back on and make preparations.

Adjustments can make a huge difference in your home, especially if below-freezing temperatures are about to hit.

“They should definitely make sure their filters are clean because clogged filters can really cause some damage and make your heating not be as efficient as it should be,” said the office manager at ADA Heating and Air, Karen Hughes. “A clogged filter can create thousands of dollars’ worth of damage when it would be much cheaper just to make sure that that filter is clean.”

Our weather authority predicts low temperatures in the 20s to 30s, with some frost possible by Tuesday morning.

“So, if your lines freeze up or if you go to see your outdoor unit and it’s frozen up or it looks like it has frost on it, that could mean that you’re low on freon. So, you would definitely need to call an HVAC specialist at that point and have somebody come out and check it out,” Hughes said.

Hughes says homeowners should get regular maintenance every six months.

“You know, getting your fall maintenance done to make sure everything runs good for the wintertime is the best thing to do,” Hughes said.

Hughes also said if you have propane heat, make sure your tank is full. She also recommends setting your thermostat in the low seventies and not overwork your system
