While many problems with your air conditioner will require a professional technician to repair the issue, we find that sometimes a homeowner can fix simple problems with a little troubleshooting. While many problems with your air conditioner will require a professional technician to repair the issue, we find that sometimes a homeowner can fix simple problems with a little troubleshooting.

When your air conditioner suddenly stops working, it can be cause for alarm or it can be something as simple as a blown fuse or tripped circuit breaker. In this article, we will guide you through troubleshooting and fixing some of the most common problems you may encounter with your air conditioner.

Your Air Conditioner Won't Turn On

If your air conditioner isn't turning on, begin by checking the outside unit to see if the condenser is running. Ensure that the unit is plugged in and your thermostat is set properly. Sometimes, a lower thermostat setting of 5 to 10 degrees can fix the problem. Also, remember to read the thermostat manual as it might have specific instructions. Additionally, check for blown fuses or tripped circuit breakers.

If your air conditioner still refuses to turn on or if your coil is frozen, it is recommended to contact a professional to repair your system.

Your Air Conditioner Is Not Cooling the Air

If your air conditioner turns on but fails to cool the air, a dirty or blocked air condenser might be the culprit. Start by cleaning around the outside unit and removing any debris or weeds that obstruct air circulation.

Next, inspect your filter and make sure it is clean. A dirty filter can restrict air to the evaporator coil, leading to freezing. Consider changing the filter more frequently if you have pets or run your air conditioner often. A simple test is to hold the filter up to the light and see if you can see through it.

If your air conditioner still doesn't cool the air, you may have a problem with your compressor or refrigerant. In such cases, it is best to contact a professional for assistance.

Your Air Conditioner Isn't Adequately Cooling Your Home

If your air conditioner is on and set properly but fails to cool your home to your desired temperature, it could be due to an undersized unit. Remember that your system should be sized to keep your home cool on an average summer day, maintaining a temperature difference of 20-25 degrees between the indoor and outdoor temperature. Your air conditioner is not designed to keep your home at 68 degrees when it is 95 degrees outside.

If it's a normal summer day and your air conditioner still can't keep up, you might have a problem with the charge or a frozen evaporator coil. If you notice icing on your outdoor unit, it's best to turn it off and call a professional.
