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

October 07, 2015

The fluctuating weather in Shelby can mean a variety of things, from the changing seasons to flicking off the switch of your air conditioner for the cooler 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 headed for AC repair though.

When your air conditioner stops working or you notice it behaving strangely, there are a couple things you can check on before calling in the team at Hopper Heating and Air for AC repair. Here are four troubleshooting tips to try before giving us a ring.

1) Check your thermostat

This is one of the easiest 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”
  • Set to be around room temperature
  • Using a newer 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 peep. 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 diminishes 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 usually 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 flip it back to the On position.

4) Open all of your vents

A common blunder among homeowners is to close vents in vacant 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 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 ring.
