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

The fluctuating weather in San Dimas can mean a variety of things, from the changing seasons to turning off the switch of your air conditioner for the cooler months. Of course, whole 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 stops working or you notice it acting strangely, there are a couple things you can check on before calling in the pros at Energy Upgrades, 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. 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 noise. 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 exchange it 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:

  • Close to 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 find out 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 typical error among homeowners is to close vents in unused rooms, but this could actually lead to a need for AC repair. Closing these vents could 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 in working order, it’s probably time to give us a shout.
