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

The fluctuating weather in Port Saint Lucie can mean a host 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 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 operating oddly, there are four things you can check on before calling in the experts at Custom Air Systems Inc for AC repair. Here are a couple troubleshooting tips to try before giving us a ring.

1) Check your thermostat

This is one of the most basic checks that homeowners can do on their own, and may solve the concern more than they’d like to admit. Ensure your thermostat is: 

  • Set to “cool”
  • Programmed to be around room temperature
  • Using 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 peep. 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 diminishes your system’s efficiency and harms airflow.

3) Find and inspect your air conditioner’s switches

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

  • Near the air conditioner itself and usually look like your stereotypical light switch.
  • At your circuit breaker panel. Identify 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 common error 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 stop working 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 call.
