Why Might My Air Conditioner Short Cycle?

When your air conditioner is functioning correctly, it cycles for about 15-minute intervals two to three times per hour. If it is short cycling, the unit's cooling cycle stops not long after it starts. Then, the cycle begins again within a few minutes. If your unit is malfunctioning like this, trust the expertise of the HVAC professionals at Panama Cool. We'll have your AC running right in no time, relieving you from the stress and discomfort of a malfunctioning unit!

Clogged Air Filter

On average, changing your air filters every three months is recommended for optimal performance. When dust and other airborne pollutants get trapped in your AC filter, they prevent the unit from having the necessary airflow to function correctly. Heat builds up within the system because of the clogged air filter. Then, your air conditioner short cycles because the condition causes the unit to falsely detect higher indoor temperatures than what exists.

Low Refrigerant

Speaking of trapped heat, another common cause of air conditioner short cycling is low refrigerant levels. Refrigerant is the chemical inside your HVAC system that flows throughout it, moving heat from indoors to outside your house. The "charge," or set level of refrigerant, should remain consistent throughout the life of your AC. Low levels are a warning sign of a leak and require professional repairs.

Failing Compressor

When a compressor cannot stay on for an extended period due to internal failures, it might start to short cycle. To prevent further damage to your AC and possibly needing a completely new appliance, contact the experts at Panama Cool. Our highly trained and experienced technicians can quickly assess the issue and efficiently restore your home's comfort levels. We value our customers and strive to be your go-to HVAC repair company in Panama City, FL.

Faulty Thermostat

Another leading cause of air conditioner short cycling is a faulty thermostat. If the thermostat isn't calibrated accurately, it sends false temperature readings to the unit. Then, the AC shuts down soon after a cooling cycle begins because the appliance receives incorrect information that your home is warmer or cooler than it is. When this happens, it's necessary to have your air conditioner repaired to correct the issue.

Leaking or Undersized Air Ducts

Leaking or improperly sized air ducts are magnets for air conditioner short cycling. In both cases, reduced airflow causes your unit to work harder, placing a strain on the appliance. Hot air is pulled inside from the outside, increasing your utility bills over time as your AC runs inefficiently.

Iced or Dirty Evaporator Coil

An evaporator coil removes heat from inside your home. However, if your evaporator coil becomes iced or dirty, your air conditioner might start to short cycle. Our certified team at Panama Cool can easily assess and repair the problem.
