Here are some of the most common suspects

A Clogged Air Filter

One of the most common causes of AC units not turning off is a clogged air filter. A dirty air filter can reduce airflow and prevent your AC from shutting off when it should. Dirty filters make it hard for your unit to cool your home thereby extending the cooling cycles. To fix this, replace the air filter with a new one as soon as possible. Experts recommend that you replace your system’s air filter every 30 to 90 days, depending on several factors. The presence of allergy or asthma sufferers in the home, for example, will require more frequent filter changes. So will the presence of pets or smokers.

Thermostat Problem

Another possible cause of your AC unit not turning off is a malfunctioning thermostat. If the temperature setting on your thermostat isn’t accurate, it can prevent the AC from shutting down when it should. This could be due to a calibration issue or it may be related to incorrect programming. Your thermostat settings can cause your AC unit to stay on long after it should have shut off. If you’ve recently adjusted the temperature or time settings of your thermostat, this could be causing the issue.

Your Air Conditioner is Too Small For the Space

If your AC unit is too small for the space it’s cooling, this can also cause it to run too long. If your air conditioner isn’t powerful enough for your home, it won’t be able to cool down the house and turn off when it should. Instead, it will stay on longer as it struggles to reach the temperature setting you’ve chosen on your thermostat. To fix this problem, you’ll need to upgrade your AC unit to a larger, more powerful model. For accurate sizing of your AC unit, contact a local HVAC technician for help.

Severe Weather Conditions

If you live in an area that experiences extreme weather conditions, this can also cause your AC to stay on longer. During periods of intense heat or humidity, it may be more difficult for the unit to reach the temperature setting you’ve chosen. This could cause it to run for longer than usual and prevent it from turning off when it should. Make sure your AC unit is properly sized for your space so it can more easily handle extreme weather conditions. To diagnose this problem, monitor your AC during the coolest periods of the day to see if it turns off. If you’re unsure, you should contact a professional HVAC technician like DeZiel Heating & AC for assistance.

Your AC is Due For Repair or Replacement

Finally, if none of the above solutions work, your AC is due for repair or replacement. If your system is over 10 years old, there may be components within it that need replacing or repairs to ensure it’s running efficiently.  Additionally, if you’ve noticed an increase in energy bills, this could also be a sign that it’s time for repair or replacement. Contact an experienced HVAC technician to diagnose the problem and make the necessary repairs or upgrade your system if need be. With these tips as a guide, you should now have a better understanding of why your air conditioner won’t turn off and how to fix the issue. Don’t forget to contact a professional HVAC technician for help diagnosing and addressing any underlying problems with your AC unit. By doing so, you’ll be able to start saving money on energy bills and improve the cooling performance of your system in no time.
