Tips to tune up your air conditioner

Posted: Updated:

PHOENIX -- It's May in the desert, which means temperatures are on the rise and people are firing up their air conditioners.

Bruce Haffner checked in with Mike Donley of Donley Service Center to find out what you need to do to make sure your a/c is in tip-top condition for the summer.

Donley said it's a good idea to test your air conditioner to make sure it's working properly before you actually need it to keep you cool.

"Make sure it comes on. Let it run for 20 or 30 minutes just to make sure it's working," he said.

If it doesn't come on, the first thing you should do is make sure there's electricity to the unit.

"The easiest way to do that is to turn the fan to the on position. You should be able to hear the blower come on," Donley explained. "If you don't get any fan at all, there's probably no power to the unit."

If there' no power, check the breaker and the fuses. Replacing the fuses yourself can save you quite a bit of money.

The simplest thing you can do to keep your air conditioner running at peak performance is change your filter regularly. It will make a huge difference in the efficiency and effectiveness of your a/c. Experts say you can use inexpensive filters as long as you remember to change them every 30 days.
