What to Check Before Calling
AC units are one of those modern day conveniences that Arizona residents simply can’t live without.
Thermostat (4 Items)
- Check the auto, cool, and temperature setting are at your comfort level. We actually receive calls for thermostats that aren’t set properly.
- Battery – some thermostats use a battery, if yours reads “battery” or “batt” take a moment to swap the old one for a new one to see if this fixed the problem.
- Dirt – remove the front panel of your thermostat to see if there’s any dust or dirt inside it. If there is dirt inside, you can use a can of compressed air to blow it out. Try not to hold the can too closely to prevent damaging and of the small parts within.
- Yoyo-ing the temperature – moving the temperature settings up and down can sometimes cause the compressor to overheat and stop running. If you have a time delay circuit, you may have to wait for the compressor to reset. Try setting the temperature to 78 degrees and leaving it for half-an-hour.
Filters: (2 Items)
- Dirty filters – most modern air conditioners use a return grill to circulate air, which typically has a filter, and many also have a filter at the air handler. Check these filters if you have them and make sure they’re not covered in dirt. A dirty filter can choke the air conditioning system and effect its performance.
- Crowding – sometimes the air handler is located in a storage closet. If yours is, be sure that you haven’t stuffed so much stuff into this area that the air handler is choking. Resist the temptation to use this closet for anything other than your air handler.
Breakers: (2 Items)
- Sometimes the circuit breaker can overload and turn off. You want to check your breaker by locating the circuit for the air conditioner and switching it off, then back on. Don’t just inspect it, actually turn it off and back on. This is a common issue that can be caused by a power surge or storm activity.
- Inspect the Air handler to make sure power reaches it when you turn the system on.
