If you’ve ever found yourself wondering why your air conditioner seems to have a mind of its own and won’t turn off, you’re not alone. It’s a common concern that can lead to discomfort and higher energy bills. In this blog post, we’ll delve into the reasons behind an AC that won’t shut off, share some troubleshooting tips, and highlight the importance of annual maintenance to keep your cooling system running smoothly.
Let’s answer the question – Why Won’t My Air Conditioner Turn Off?
There are 8 things that can often cause your AC to run continuously.
-
Thermostat Settings
One of the primary reasons your air conditioner might refuse to take a break could be thermostat related. Check if your thermostat is set to the desired temperature and in the correct mode (cooling). Also check to be sure you are not set in a schedule on the thermostat. Sometimes, a faulty thermostat or improper settings can lead to continuous operation. Also, be sure to check the fan settings on the thermostat. If the fan is set to ON instead of AUTO, then you will think the AC is always running when in reality the fan is continuously running.

Clogged or Dirty Filter
Clogged or dirty air filters cause obstructed airways, forcing your AC to work tirelessly to achieve the desired temperature. Regularly replacing or cleaning filters is a simple yet crucial step to maintain optimal airflow and prevent continuous operation.
-
Low Refrigerant
Low refrigerant levels or leaks can compromise your AC’s cooling efficiency, resulting in a system that runs non-stop. Professional assessment and replenishment of refrigerant levels are essential to rectify this issue and restore your AC to peak performance.
-
Electrical Issues
Electrical issues can disrupt the normal functioning of your AC. From faulty wiring to malfunctioning components, these glitches require the expertise of a qualified technician to diagnose and address effectively. Some common electrical issues may be a stuck relay switch or a bad contactor. In both cases the AC will receive constant power and continue to run. Sometimes these issues may be repaired, but often the parts themselves need to be replaced to ensure proper operation.
-
Dirty Condenser
A neglected AC unit laden with dirt and debris can cause improper airflow within the unit, leading to continuous operation. Regular cleaning and maintenance of your AC unit are paramount to ensure the system operates efficiently and maintains a comfortable indoor environment.
-
Dirty Evaporator Coils
Evaporator coils are inside your indoor air handler unit or attached to the furnace, but they are vital in your air conditioner’s ability to cool air. They remove heat from the air in your home using a refrigerant that runs through a copper tubing. Dirty evaporator coils can hinder the heat exchange process, forcing your AC to work harder and longer. Professional cleaning and maintenance of evaporator coils are essential to ensure your system operates at its full potential. If you are somewhat knowledgeable in HVAC this task could be done on your own, but in most instances it’s best to call for repair.
-
Temperature Extremes
Your air conditioner is sized for the normal temperatures in your region, not the very extreme. So, if you are having a heat wave it is normal that your AC may be running continuously in order to keep up.
-
Undersized AC
An AC unit that is too small for the space it serves can contribute to continuous operation. Proper sizing and evaluation of the system’s capacity are essential considerations to ensure it meets the cooling demands of your home.
The Importance of Annual AC Maintenance
Prevention is often the key to avoiding prolonged AC woes. Annual maintenance conducted by skilled technicians offers a comprehensive checkup of your system. This proactive approach allows for the identification and rectification of potential issues before they escalate, ensuring the longevity and efficiency of your air conditioning system.
