Air Conditioner Troubleshooting: What to Do Before Calling for AC Repair

October 07, 2015

The shifting weather in Phoenix can mean a host of things, from the changing seasons to turning off the switch of your air conditioner for the chilly months. Of course, whole home comfort is your year-round goal, but sometimes our heating and cooling equipment doesn’t feel like doing that. That doesn’t mean that you’re predestined for AC repair though.

When your air conditioner stops working or you notice it acting weirdly, there are a couple things you can check on before calling in the pros at Dial One Mears Air Conditioning & Heating Inc for AC repair. Here are a few troubleshooting tips to try before giving us a shout.

1) Check your thermostat

This is one of the most basic checks that homeowners can do independently, and could solve the problem more than they’d like to admit. Make sure your thermostat is: 

  • Set to “cool”
  • Set to be around room temperature
  • Using a newer battery

2) Look at the air conditioner filter

Dirty filters can cause air conditioners to act weirdly, making them shut down without notice and without making a sound. Air conditioner filters have been the cause for a lot of AC repair calls in the past, but there’s no reason to pick up the phone when you can swap it out yourself. Not to mention that a dirty air conditioner filter diminishes your system’s efficiency and reduces airflow.

3) Find and inspect your air conditioner’s switches

The majority of the time, switches to your air conditioner are found:

  • Around the air conditioner itself and normally look like your everyday light switch.
  • At your circuit breaker panel. Pinpoint the breaker that controls your air conditioner and figure out if it is in the middle position or the Off position. If it is, cycle the breaker to Off and then switch it back to the On position.

4) Open all of your vents

A typical error among homeowners is to close vents in unused rooms, but this may actually lead to a need for AC repair. Closing these vents can potentially cause your system to be less efficient and stop working because of added airflow pressure.

If you’ve done these four troubleshooting tips and still aren’t having any luck getting your system back operating, it’s probably time to give us a shout.
