An air conditioning unit comprises multiple components that work together to extract heat and pump cool air into your home. Without routine maintenance, you’ll notice changes in operation that could be attributed to a variety of problems. For example, short cycling is a symptom that outdated units often experience. Learn why this is a problem and what underlying issues might need to be addressed with the guide below. 

What Is It?

When the air conditioning unit is working properly, it should complete a full cooling cycle before shutting off. A unit short cycles when it powers down before reaching the temperature setting on the thermostat.

Constantly turning on and off strains the components, causing the system to drain more energy. You could be spending more money to operate equipment that isn’t even cooling your home properly. The tension also increases the risk of a system breakdown.

Why Short Cycling Happens

With a thorough examination of the system, an air conditioning contractor can pinpoint the reason for short-cycling problems. The unit should be sized according to the property’s square footage. A large unit designed for a multistory house will cool a studio apartment quickly, causing the system to shut off abruptly. 

A technician might also need to check the evaporator coil. When this component is dirty or frozen, it can’t absorb heat efficiently. The system might overheat and shut off as a safety precaution.

When running the system with a dirty filter, short cycling can occur. Air can’t pass through the clogged screen, and trying to force it through the system causes the equipment to shut down before the cycle is complete.
