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

October 07, 2015

The changing weather in Port St. Lucie 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 headed for AC repair though.

When your air conditioner fails to work or you notice it acting strangely, there are a few things you can check on before calling in the pros at Custom Air Systems Inc for AC repair. Here are four troubleshooting tips to try before giving us a call.

1) Check your thermostat

This is one of the most basic checks that homeowners can do independently, and could solve the issue more than they’d like to admit. Be sure your thermostat is: 

  • Set to “cool”
  • Set to be around room temperature
  • Utilizing a newer battery

2) Look at the air conditioner filter

Dirty filters can cause air conditioners to act weirdly, 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 change it yourself. Not to mention that a dirty air conditioner filter lowers your system’s efficiency and harms airflow.

3) Find and inspect your air conditioner’s switches

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

  • Around the air conditioner itself and usually look like your stereotypical light switch.
  • At your circuit breaker panel. Find 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 routine error among homeowners is to close vents in unused 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 turn off because of added airflow pressure.
