What to Do When Your AC Won’t Stop Running


Did you know that the highest maximum temperature recorded on the planet was 134 degrees in July of 1913? If you want to avoid hot days, you likely stay home in the comfort of your air conditioning.

However, an AC can cause problems of its own. For example, if your AC won’t stop running, you could be in for a repair sooner than later.

Not sure what to do when this happens? Keep reading to find out.

Adjust Thermostat Temperature Settings

If your AC won’t stop running, first try adjusting your thermostat’s temperature settings. The air conditioner cycle will keep running if the set temperature is lower than the temperature in the room.

Adjust the temperature a little higher than the room temperature. This might trigger the thermostat to shut down the AC.

Adjust Thermostat Fan Settings

If an AC fan won’t stop running, it might appear as if the cooling cycle is constantly going. If the fan is running alone, check the fan settings on your thermostat.

The thermostat should say that the fan is on AUTO. This means that the fan will only run while the air conditioner is on. If the fan setting is ON, switch it to AUTO so that it will stop running with your AC.

Eliminate Airflow Restrictions

When your air conditioner won’t stop running, you might need to eliminate airflow restrictions. Obstacles can prevent air from freely flowing through your system, forcing the AC to stay on longer than it needs to.

Clean dirt and debris from the outdoor condenser unit, replace a dirty air filter and open the supply vents in each room throughout the home.

You might also need to clean the blower fan. If the air conditioner is not blowing cold air but running, it could be because of the blower fan dirt and grime.

Call the Experts

If the above methods don’t work to stop your AC from continuously running, you are likely dealing with a more technical issue.

You might need an air conditioner repair and, in severe cases, a complete air conditioning installation. An expert can get to the bottom of your issue to determine what the best plan of action is.

These are some of the many reasons that your air conditioner is not turning off:

  • Electrical issues
  • Faulty thermostat
  • Faulty fan limit switch
  • Low fan speed
  • Incorrect system size

These are more serious problems that only a professional should fix.
