GROTTOES, Va. -- A lot of folks have avoided turning on the AC to cut costs, but on a week like this one, with a heat wave, it's too hot to keep it off.
That's why you should use your air conditioning in the most economical way possible.
Co-owner of Fire and Ice Heating and Air Conditioning Ronda Davis says having a central AC unit is more cost efficient for you in the long run, opposed to the window units.
Plus, she says it adds equity to your home by about $10,000.
As for window units, Davis says try to keep them in the shade because they work better when they're cooled off. But she says most people have them in whichever room they need it, not based on whether it's in the sun.
Davis says for the best results to keep cool at home, keep your AC around 70 to 75 degrees on hot days because changing it up when you're not home won't end up saving you money.
"It's gotta get the humidity out so on these hot, humid days it's going to take a long time to get it back out," said Davis. "Now if you're gone on vacation, yes you can set it up 5, 6, 7 degrees or something like that, but not if it's overnight or while you're at work. Just set it and forget it."
Other tips to keep cooler are to keep windows and doors closed as much as possible, keep shades down, and switch out your air filter every month.
