Having a functional and efficient air conditioner system is essential in maintaining a comfortable environment, especially in these hot summer months. However, when you encounter a situation where your AC won’t turn off, it can be frustrating and concerning. Air Supply Heating & Air Conditioning will discuss some of the common reasons why your AC is failing to shut off.

Thermostat Malfunction

A faulty thermostat is a common culprit when your thermostat refuses to turn off. The thermostat acts as a control center regulating the temperature in your home. If the thermostat malfunctions, it may fail to communicate the correct temperature to the AC unit. Check if the thermostat is set to the desired temperature and working correctly. Resetting or replacing the thermostat may be necessary if it is found to be faulty. You should also check to see if the fan setting is on. If the manual setting is on, it will have the fan keep running, no matter the temperature of the thermostat.

AC System is Clogged or Blocked

While a faulty thermostat may be a very common culprit for your AC not turning off. There may be other reasons why you are having this issue. You may have dirty, blocked, or clogged parts in your AC. When this happens it makes it hard for your AC to go through its cycle to reach the temperature you have set. If you have dirty, condenser coils, dirty air filters, or frozen evaporator coils, this could cause your AC to not turn off because it has to work extra hard to try to cool down your house.

DIY AC Troubleshooting

When you notice your air is not turning off, you can try a few things before you have to call a professional for help. Try to adjust the thermostat fan setting. Make sure the fan is set to on and make sure the setting is to auto, you can always raise the temperature to your AC to see if it will turn off. If it does not, then there is a chance it is a sensor or wiring issue and a professional should be called to come take a look.

Clean AC Unit

If you have dirty air filters, then you need to change them and clean them out. You should be doing this every one to three months so that it does not cause problems and get too clogged for your AC. You can clean your blower fan and blades also. Make sure to remove any debris that is around your blades. Make sure to turn off your AC and remove the electrical outlet before you attempt to clean them.
