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

The fluctuating weather in Mobile can mean a host of things, from the changing seasons to flipping 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 helping us out. That doesn’t mean that you’re automatically destined for AC repair though.

When your air conditioner stops working or you notice it behaving weirdly, there are four things you can check on before calling in the team at Farnell Heating & Air Conditioning 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 easiest checks that homeowners can do on their own, and may solve the problem more than they’d like to admit. Be sure your thermostat is: 

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

2) Look at the air conditioner filter

Dirty filters can cause air conditioners to act out of the ordinary, making them shut down without notice and without making a peep. Air conditioner filters have been the cause for quite a few 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

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

  • Close to the air conditioner itself and typically look like your regular light switch.
  • At your circuit breaker panel. Pinpoint 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 vacant 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 turn off because of added airflow pressure.

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