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

October 07, 2015

The shifting weather in the Rio Grande Valley 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, total 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 automatically destined for AC repair though.

When your air conditioner fails to work or you notice it acting weirdly, there are a couple things you can check on before calling in the pros at Cytech Heating & Cooling L.C. for AC repair. Here are four troubleshooting tips to try before giving us a call.

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. Be sure your thermostat is: 

  • Set to “cool”
  • Set to be around room temperature
  • Working with a new 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 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 exchange it yourself. Not to mention that a dirty air conditioner filter decreases 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:

  • Close to the air conditioner itself and typically look like your regular light switch.
  • At your circuit breaker panel. Identify 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 flip it back to the On position.

4) Open all of your vents

A typical mistake among homeowners is to close vents in unused rooms, but this may actually lead to a need for AC repair. Closing these vents can potentially cause your system to be less efficient and turn off because of added airflow pressure.

If you’ve completed these four troubleshooting tips and still aren’t having any luck getting your system back up and running, it’s probably time to give us a ring.
