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

October 07, 2015

The shifting weather in Des Moines can mean a variety of things, from the changing seasons to flipping 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 doing that. That doesn’t mean that you’re predestined for AC repair though.

When your air conditioner stops working or you notice it operating oddly, there are a few things you can check on before calling in the pros at Heartland Heating & Cooling 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 independently, and could solve the issue more than they’d like to admit. Make sure your thermostat is: 

  • Set to “cool”
  • Tuned 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 weirdly, 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 swap it out yourself. Not to mention that a dirty air conditioner filter diminishes your system’s efficiency and inhibits airflow.

3) Find and inspect your air conditioner’s switches

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

  • Near the air conditioner itself and normally look like your regular 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 flip it back to the On position.

4) Open all of your vents

A typical error among homeowners is to close vents in unused rooms, but this might actually lead to a need for AC repair. Closing these vents can 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 up and running, it’s probably time to give us a ring.
