What is short cycling?

Short cycling is a damaging process that occurs when an air conditioner turns on and off repeatedly within a short amount of time. On average, a cycle should last around 10 to 20 minutes. However, if you notice that your HVAC system is switching on and off in less time than that - typically somewhere between one and five-minute intervals - your unit is short cycling.

The compressor and fan motors require sufficient time to cool down. Without the necessary rest between functions, your unit is at risk of severe damage. It's crucial to contact the experts at Reliable Heating & Cooling for tune-ups and repairs as soon as possible. Early intervention can prevent further issues that become costly if not handled promptly, potentially saving you a significant amount of money in the long run.

Oversized Units and Dirty Filters

One likely culprit is an AC that is too big for your home's cooling needs. An oversized air conditioner drops the temperature inside your house too quickly, leading to short cycling. Dirty air filters reduce the airflow over the evaporator coils. The lines can eventually freeze, and the compressor overheats because the coolant isn't given sufficient time to remove the excess warmth before returning to the condenser. The result is cycles that begin and end too quickly, causing damage to your HVAC system.

Compressors and Condenser Fan Motors

If your compressor is on the fritz, your condensing unit will be unable to function correctly. Faulty capacitors are among the most frequently replaced AC parts. A malfunctioning condenser fan motor is another common reason air conditioners short cycle. You will likely notice an increase in humidity levels as the system begins to struggle to remove the excess moisture in the air.

Other reasons your air conditioner might experience problematic short cycling are:

• Frozen evaporator coils
• A broken thermostat
• Low refrigerant levels
• A faulty control board
• Electrical issues
• A clogged drain line
• The AC voltage is wrong

Possible Outcomes

What happens if you don't have a short-cycling air conditioner repaired? The additional power consumption will increase your energy bills. The heavy strain could also cause your compressor to wear out sooner than necessary.
