My Air Conditioner Shuts Off All the Time—What Do I Do?

air conditioner shuts off all the timeNow that we’re finally shaking off those last chilly days of spring, it’s more and more important that your AC is operating in peak condition. So what do you do if your air conditioner shuts off all day long—and how do you know if it’s something you should be worried about?

One of the most common reasons we see for air conditioners shutting off frequently is short cycling. This means that your system is turning off and on again too often and not allowing your home to reach the desired temperature set on the thermostat—not only is this frustrating, but it’s inefficient, too!

Why Does My Air Conditioner Always Shut Off?

There are a number of reasons why your air conditioner could be shutting off all the time, including:

  1. Compressor issues – The compressor is the engine of your air conditioner’s system. It’s where refrigerant cycles through the unit and is responsible for generating the pressurized conditions under which the refrigerant absorbs and dissipates thermal energy. It is often a sealed component so that dust and debris cannot damage its internal moving parts, but if it’s overheated or simply old and worn out, it may shut off all the time. An air conditioner compressor can break for several possible reasons, such as a blown fuse (commonly caused by the compressor tripping the breaker), a broken motor overload protector, or burnt wiring.
  2. Low refrigerant – The level of refrigerant in your air conditioner needs to be consistent and balanced in order for it to work properly. When your air conditioner was installed, your unit was given a certain “charge,” but if the level of refrigerant falls below this, it can lead to inadequate cooling and energy inefficiency. Plus, it may be another cause why your air conditioner shuts off all the time.
  3. Frozen coils – The evaporator coil in your indoor air handler is responsible for cooling the warm air drawn from the interior of your home, but if you have a clogged air filter or some other airflow issue, that allows frost to build up on your evaporator coils. This, of course, is less than optimal and can cause a whole slew of problems for your system—including short cycling.
