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

The shifting weather in Grand Prairie can mean a variety of things, from the changing seasons to flipping off the switch of your air conditioner for the cooler months. Of course, total 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 strangely, there are a couple things you can check on before calling in the experts at Mustang Mechanical 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 most basic checks that homeowners can do independently, and might solve the issue more than they’d like to admit. Ensure your thermostat is: 

  • Set to “cool”
  • Tuned to be around room temperature
  • Utilizing a fresh battery

2) Look at the air conditioner filter

Dirty filters can cause air conditioners to act erratically, 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 swap it out yourself. Not to mention that a dirty air conditioner filter decreases your system’s efficiency and inhibits airflow.

3) Find and inspect your air conditioner’s switches

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

  • Near the air conditioner itself and typically look like your everyday light switch.
  • At your circuit breaker panel. Find 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 flip it back to the On position.

4) Open all of your vents

A common error among homeowners is to close vents in unoccupied rooms, but this may actually lead to a need for AC repair. Closing these vents could 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 in working order, it’s probably time to give us a shout.
