If your cooling system keeps running continuously, this guide is exclusively for you. Here, our experts will share common reasons why your air conditioner won’t turn off and what you can do about it.

Top Reasons Why Your Air Conditioner Won’t Turn Off

A malfunction in one of the following categories is likely to be the reason why your cooling system does not shut off:

Incorrect Thermostat Settings

If your thermostat is not set accurately, it will not allow your cooling unit to shut off properly. For example, if the fan is in ON mode instead of AUTO, it will run automatically. Similarly, if you have adjusted the thermostat settings less than usual, your AC may keep running long past when you expect to shut it off.

Thermostat Malfunction

A typical thermostat has a lifespan of about 10 years. After that period, it may not work efficiently, leading to several air conditioning issues. Also, if the thermostat collects dirt and debris on temperature sensors, it will mislead your room temperature, leaving your cooling unit running constantly.

Undersized Air Conditioner

It is vital to choose the right-sized cooling unit for your home, otherwise, it will result in premature AC repairs. If your unit is undersized and does not have the cooling capacity your home needs, it will run seemingly around the clock to satisfy your cooling needs.

Additionally, if your AC is too small for your room, it will waste a great amount of electrical power, with cycles lasting for hours.

Dirty Air Filters

Your system’s air filters trap all kinds of particles and pathogens in the air. Though air filters help improve indoor air quality, they can become saturated over time. Dirty and clogged air filters restrict cool air from circulating correctly throughout your home. Also, it can cause your system to overwork, leading it to run constantly. In order to keep your system working efficiently, make sure to change your air filters every 30 to 90 days.

Frozen Evaporator Coils

Evaporator coils are critical in determining how your air conditioning system cools the air. Located in the air handler unit, these coils are where the hot air is absorbed and cooled by refrigeration.

Evaporator coils may freeze if they don’t encounter sufficient heat. The problem often arises due to a clogged condensate drain or airflow blockage. Plus, a refrigerant leak can worsen ice accumulation on the coils.
