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

October 07, 2015

The fluctuating weather in Tucson 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, total home comfort is your year-round goal, but sometimes our heating and cooling equipment doesn’t feel like cooperating. That doesn’t mean that you’re predestined for AC repair though.

When your air conditioner quits working or you notice it behaving weirdly, there are a few things you can check on before calling in the pros at A&M Heating & Cooling LLC for AC repair. Here are a few troubleshooting tips to try before giving us a ring.

1) Check your thermostat

This is one of the easiest checks that homeowners can do independently, and may solve the issue more than they’d like to admit. Be sure your thermostat is: 

  • Set to “cool”
  • Tuned 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 noise. 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 change it yourself. Not to mention that a dirty air conditioner filter diminishes your system’s efficiency and inhibits airflow.

3) Find and inspect your air conditioner’s switches

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

  • Near the air conditioner itself and typically look like your stereotypical light switch.
  • At your circuit breaker panel. Identify the breaker that controls your air conditioner and determine 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 routine blunder among homeowners is to close vents in unoccupied rooms, but this might actually lead to a need for AC repair. Closing these vents may potentially cause your system to be less efficient and shut down because of added airflow pressure.

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