What to know before turning on your AC

YORK, Pa. (WHTM) – HVAC companies are receiving dozens of calls from people whose air conditioners aren’t working. Experts at YTI Career Institute gave ABC27 a checklist to follow before and after you turn on your air conditioner this summer.

Step one: check your filter. Make sure it doesn’t need to be cleaned or replaced.

Step two: check your outdoor unit.

“Make sure there’s no grass, bushes. If you cover it in the winter time, make sure you take the covers off,” said Richard George, a heating and air conditioning instructor.

Once that’s done, there’s a few dos and don’ts to keep in mind.

Do set your thermostat to a comfortable temperature and leave it there. Only bump it up a few degrees if you’re going to be away for an extended period of time.

“It’s actually harder on the equipment to turn it off and on than it is to just let it operate,” George said.

Don’t close any returns.

“You can close supplies in a small amount of your house and still get away with it, but it’s not a good idea,” George said.

If you’ve checked the filters, the outdoor unit, the breaker, the wires, and it still isn’t running:

“Then you gotta call somebody,” George said. “The best way to run your system is to treat your house in the winter the same way you treat it in the summer.”

George recommends you change your filter at least three times a year, and have a company check out your entire system once a year.
