Troubleshooting: What To Do When Your System Isn’t Cooling Properly


There’s nothing quite like stepping into a cool, air-conditioned home after spending time outdoors on a hot summer day. That is, if it’s working properly. Air conditioning systems are subject to their fair share of issues over time, and many of these problems can cause the system to not cool a property properly. 

There are several troubleshooting steps you can take first before you schedule a service call.


What Should I Do If My Air Conditioner Isn’t Cooling Properly?

Curious what steps you should take if you notice a problem with your air conditioner before calling in an expert? Here’s a look at some basic AC troubleshooting:

  • Check Your Electrical Panel

If your air conditioner won’t even kick on when it’s activated, the first thing you should do is check your electrical panel. The fix could be something as simple as flipping a breaker switch that may have tripped. If everything looks good there, check to see if you may have blown a fuse. If you suspect this is the case, you should be able to find a replacement at your local hardware store and make the switch yourself. 

  • Check Your Thermostat

Another common culprit is your thermostat. You’d be surprised to learn that if an air conditioner isn’t kicking on, sometimes it’s because the thermostat isn’t set to cool air. So make sure you check your thermostat to ensure that it’s set properly. 

  • Check to Make Sure it’s Air Flow is Working Properly

Head outside to your AC unit to make sure there are no obstructions. Air conditioners need clearance in order to receive proper airflow. If there are bushes, trees or other growth encroaching on the unit, problems could arise. Sometimes, just taking your hedge trimmers to whatever is growing near your air conditioning unit is enough to improve airflow around the system and restore proper cooling to your home.

  • Change the Filter

Is the air conditioner kicking on, but airflow weak out of the vents? Try changing out the filter. If the filter becomes too soiled, it can restrict airflow through the vents and to the rest of the home. Air filters are usually very easy to check and change out. Make sure you know how often you should be changing yours to avoid future problems. Changing the filter will also minimize wear and tear on your unit and help it operate more efficiently. This can also help you save money on your energy bills.
