Have you noticed that your air conditioner frequently starts and stops on its own? This is a troublesome problem that can increase your energy costs while also reducing your comfort. Short cycling is the formal name for this issue.
It happens when the air conditioning machine runs for a brief period, shuts off, and then restarts.
Short cycling might potentially damage the AC’s parts, necessitating costly maintenance or replacement. In this article, we will explore the common causes of AC short cycling and provide solutions to fix the issue.

Dirty air filter
A dirty air filter can cause short cycling by reducing the airflow, making the AC work harder than it should. When the air filter is clogged with dirt and debris, the AC unit may shut off to prevent damage to the compressor. To prevent this problem, make sure to replace the air filter regularly, ideally every 30 to 60 days.
Refrigerant leak
A refrigerant leak can also cause the AC to short cycle as the refrigerant level drops below the normal level. When this happens, the AC unit may turn off to prevent further damage to the compressor. To check for a refrigerant leak, look for signs of oil or refrigerant around the AC unit or listen for a hissing sound. If you suspect a refrigerant leak, contact a professional HVAC technician to repair the issue.
Faulty thermostat
A faulty thermostat can also cause the AC to turn on and off repeatedly. If the thermostat is malfunctioning, it may not accurately sense the temperature in the room and may cause the AC unit to cycle on and off. To solve this issue, try replacing the batteries or upgrading to a new programmable thermostat.
Oversized or undersized AC unit
An improperly sized AC unit can cause short cycling. An oversized AC unit cools the room too quickly, causing the unit to turn off before reaching the desired temperature.
On the other hand, an undersized AC unit runs continuously to maintain the temperature, causing the unit to overheat and turn off. To avoid this problem, ensure that your AC unit is correctly sized for your room or home.
Dirty condenser coils
Dirty condenser coils can cause the AC to short cycle by reducing the efficiency of the AC unit. When the condenser coils are covered with dirt and debris, they can’t dissipate heat effectively, causing the AC to turn off to prevent overheating. To prevent this issue, make sure to clean the condenser coils regularly, ideally once a year.
In conclusion, short cycling is a common issue that affects air conditioning systems, but it can be prevented or fixed by following the above solutions. If the problem persists, it’s best to contact a professional HVAC technician to diagnose and repair the issue.
Remember, regular maintenance and cleaning of the AC unit can prevent short cycling and prolong the lifespan of your air conditioning system.
