HVAC FAQ: Why Is My System Running in Short Bursts?

If you listen to your air conditioner closely, you’ll know when it’s time to call a Lafayette AC repair company. One such time is when your system runs in frequent short bursts. This common issue is known as short cycling.

Several underlying problems could be causing your system to short cycle. Knowing more about these factors can help you decide when to call for a repair. 

You Have Clogged Air Filters

It’s important to clean or replace your unit’s air filters regularly.

Dirty filters block the passage of air through the system, which makes the system work harder to compensate for the reduced airflow. Specifically, the compressor and blower will become strained. They’ll run until they overheat, eventually causing the system to short cycle. Routinely replacing your filters will prevent this issue. 

The Thermostat Is in a Poor Position

Sometimes, the thermostat isn’t in a good position in the house. If it’s located near a heat source or window that receives direct sunlight, the sensors can be tricked into thinking that the space is too warm and trigger the system to turn on, only to shut off again quickly.

Your best bet is to relocate the thermostat to a better position or cover it to prevent the problem.

Your Evaporator Coil Is Frozen

Your unit’s evaporator coil helps remove heat inside the house. If it’s dirty or frozen over, it won’t work as designed. It can also overheat, causing the unit to automatically shut off to prevent damage.

Several different mechanical issues can result in frozen coils. To determine the underlying cause, you may need to schedule an appointment with a Lafayette AC repair company.

Your Refrigerant Levels Are Low

Refrigerant is like gasoline for your car — without it, the entire system ceases to work. 

This liquid circulates and transfers heat from the inside of your home to the outside. If there’s a leak or the supply runs low, the system is forced to work harder to keep your home comfortable. This puts additional stress on the system and eventually causes short cycling.

Only a trained HVAC technician can check and recharge your refrigerant. They can also detect and repair leaks, which are a bigger issue.
