Is the air conditioning unit in your Las Cruces, New Mexico, home short cycling? Many problems can cause this common issue. But a dirty filter, an oversized unit, low refrigerant levels or frozen evaporator coils are often to blame.

Clogged Air Filter

A dirty air filter can lead to short cycling. A clogged filter restricts airflow through the HVAC unit, forcing it to work harder than it should. This results in excess pressure on the unit, which can cause short cycling as well as many other issues. To avoid this, check your filter every month. Change it before it becomes clogged with dirt and debris.

Your AC is Too Big

An oversized air conditioning unit is a common cause of short cycling. Oversized units cool your home too quickly. They blast your home with a large supply of cold air that rapidly dissipates, causing the unit to cycle on shortly after shutting off. To make the problem worse, short cycles don’t give the unit enough time to adequately dehumidify your home, which can lead to a stuffy, uncomfortable living environment. If you suspect your unit is too large, have an HVAC professional inspect it.

Low Refrigerant Levels

Inadequate levels of refrigerant are another cause of short cycling. When your unit doesn’t have enough refrigerant, it’s forced to operate under stress, which can cause it to malfunction. Low refrigerant levels are almost always caused by a leak. So if you suspect your levels are too low, have your unit inspected and serviced as soon as possible.

Frozen Evaporator Coil

When it’s frozen, your evaporator coil cannot adequately remove heat from the air in your home. As a result, the unit will short cycle. This typically happens due to a lack of preventive maintenance. Schedule maintenance regularly to prevent this problem.
