If you’ve become frustrated by the way your air conditioner keeps shutting off, you need to call us at 301-990-7970 for professional AC repair services.

A typical problem we see occurs when air conditioners short cycle. This means they frequently turn on and off again—often with no apparent reason, and often before the home has reached the desired temperature. This can be both frustrating and inefficient.

In today’s post, we’d like to share with you some reasons why this might be happening to your AC unit:

Compressor Issues

The compressor is the engine of your AC unit’s refrigerant cycle 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 is subject to overheating or has become worn out, it may indicate this by shutting off frequently. An AC 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.

Low Refrigerant

The level of refrigerant in your AC needs to be consistent in order for it to work properly. When you scheduled AC installation, 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. It can even cause your AC to short cycle. As such, AC refrigerant leaks should be dealt with immediately.

Frosty Coil

An AC unit’s evaporator coil resides in the indoor air handler and 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, then frost can build up on your evaporator coils. This can cause your system to shut off frequently. If your air conditioner freezes, call us for repair services.

This should give you a better understanding of why your AC unit keeps shutting off. Remember—all AC repairs should be carried out by a professional. Contact us today if you need AC repair services in Gaithersburg, Germantown, Potomac, Clarksburg, or other nearby areas in Montgomery County, MD.
