Your AC Troubleshooting Guide

Our Georgia summers are hot, hot, hot. Air conditioners are essential to keeping your home cool and comfortable in this area. When your AC breaks down, it is nothing short of an emergency. Often, simply opening a window or running a fan isn’t going to do enough to bring the inside temperature down on a particularly hot summer day. You’ll need to call a HVAC technician to come out and look at it. If you have a pretty good idea of what’s wrong, you can tell them over the phone or when they arrive and it will help the entire ordeal go a lot faster. It’s not as difficult as you may imagine to diagnose a broken AC on your own. Let’s discuss a few troubleshooting tips so you can get your AC back up and running as soon as possible.

Troubleshooting Tips

#1 Check the thermostat. Double-check this before you assume that your AC unit is broken. Have you checked the batteries in your thermostat lately? If you haven’t changed the batteries in a long time, you might be dealing with a dead battery. Also, make sure the thermostat is set properly. Sometimes, fixing your air conditioner is as simple as learning to set the thermostat so it runs the way you want it to. 

#2 Replace the air filter. If the filter gets too dirty, the air cannot flow properly. As a result, your air conditioner won’t work to its full potential. Eventually, it may not run at all. The filter should be changed about every 90 days. If you can’t remember the last time you changed the filter, it’s time to change it.

#3 Flip your circuit breaker. The next thing you can try is checking your circuit breaker. If the circuit breaker connected to the air conditioner has been tripped, you’ll need to reset it. This is a simple fix, yet one that nearly everyone doesn’t think to do. Do this before calling in a professional.

#4 Check the air vents. Make sure that all of your air ducts and vents are clear. If they get clogged by dust, debris, or dirt, your cool air can’t flow properly. Your HVAC technician may need to simply clean your air vents. There may also be issues within the air ducts that you can’t see without getting up close. Things like mold or a pest infestation can prevent your HVAC from working properly. This could be the answer to your problems!
