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

The changing weather in Opelika can mean a variety of things, from the changing seasons to flicking off the switch of your air conditioner for the chilly months. Of course, complete 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 operating weirdly, there are a few things you can check on before calling in the pros at Farnell Mechanical, Inc. for AC repair. Here are a few troubleshooting tips to try before giving us a call.

1) Check your thermostat

This is one of the simplest checks that homeowners can do on their own, and may solve the issue more than they’d like to admit. Make sure your thermostat is: 

  • Set to “cool”
  • Programmed to be around room temperature
  • Working with 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 many 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 reduces airflow.

3) Find and inspect your air conditioner’s switches

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

  • Close to the air conditioner itself and normally look like your stereotypical 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 re-set it back to the On position.

4) Open all of your vents

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

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