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

October 07, 2015

The changing weather in Los Angeles can mean a variety of things, from the changing seasons to turning 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 automatically destined for AC repair though.

When your air conditioner fails to work or you notice it behaving strangely, there are four things you can check on before calling in the team at AZ Air Conditioning and Heating 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 simplest checks that homeowners can do themselves, and could solve the problem more than they’d like to admit. Ensure your thermostat is: 

  • Set to “cool”
  • Programmed to be around room temperature
  • Utilizing a new 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 sound. 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 exchange it yourself. Not to mention that a dirty air conditioner filter lowers 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:

  • Near the air conditioner itself and normally look like your everyday light switch.
  • At your circuit breaker panel. Find the breaker that controls your air conditioner and figure out 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 blunder among homeowners is to close vents in unoccupied 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 operating, it’s probably time to give us a shout. The pros at AZ Air Conditioning and Heating in Los Angeles are here to ensure all of your AC repair needs are met, so give us a call at 800-296-5088 to set up an appointment with us.
