If you’ve noticed your AC unit frequently turns on and off in short bursts, you might be dealing with an issue known as AC short cycling. This not only affects your comfort but can also increase your energy bills and put undue stress on your air conditioner, potentially leading to early failure.
At Henley’s Plumbing & Air, our family has been tackling HVAC challenges like these since 1983 to keep local homes comfortable year-round. So, what causes short cycling? And what professional fixes can restore the efficiency and functionality of your system? Find out below.
What Is AC Short Cycling?
AC short cycling occurs when your air conditioner starts its cooling cycle but then shuts off after only a short time — often before your home has adequately cooled. This repeated on-and-off pattern can be frustrating and may signal deeper issues within your system.
Understanding the mechanics behind AC short cycling is helpful in identifying solutions that extend the lifespan and performance of your unit.
Common Causes of AC Short Cycling
Several factors can cause your air conditioner to short cycle, including:
Oversized AC Units
An oversized air conditioner can cool your home too quickly, causing it to turn off before it has a chance to properly circulate the air and manage humidity levels. This rapid cooling and frequent shutting down can lead to short cycling.
Clogged Air Filters
A clogged air filter restricts airflow, forcing the air conditioner to work harder and cycle off prematurely. Regular maintenance checks can catch this common issue before it leads to more significant problems.
Low Refrigerant Levels
Refrigerants are essential for cooling your home. If there’s a leak, or if the levels are low, the pressure in your system changes, potentially causing your unit to shut down unexpectedly and frequently.
Faulty Thermostat
A malfunctioning thermostat that incorrectly reads temperatures or is poorly positioned can lead to erratic AC behavior, including short cycling.
Electrical Issues
Problems with your AC’s electrical wiring, capacitors, relays, or sensors can disrupt the communication and power flow within the unit, leading to short cycling.
