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

October 07, 2015

The changing weather in Des Moines 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, total 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 headed 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 experts at Kohles & Bach Heating & Cooling for AC repair. Here are a couple 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 themselves, and could 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 out of the ordinary, making them shut down without notice and without making a noise. 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 decreases 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:

  • Close to the air conditioner itself and usually look like your everyday 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 re-set it back to the On position.

4) Open all of your vents

A typical mistake 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 shut down because of added airflow pressure.

If you’ve done 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 call.
