Why Your AC Trips the Circuit Breaker

If you keep having problems with circuit breakers tripping when you turn on or are running your air conditioner, you should find the source of the problem and fix it rather than risk further damage to your system by continually resetting the breakers. If you can’t figure out why the A/C is tripping the circuit breaker in your home, contact your trusted Shreveport HVAC contractor for professional troubleshooting and repairs.

Here are several possible reasons why the A/C is tripping the circuit breaker.

Faulty Circuit Breaker or Wiring

The circuit breaker itself may be the problem. Breakers can deteriorate over time due to temperature changes and routine wear. If the electrical contacts or wiring are getting loose, the breaker may trip even before you try to turn your air conditioner back on.

Dirty Air Filter

A severely clogged air filter can make the air handler work harder than it’s designed for to try to move sufficient air through the ductwork. If the air handler draws too much current, the circuit breaker will trip.

Dirty Condenser Coil

If the condenser coil gets clogged with dust, leaves, or other debris, or if the fan inside the outdoor unit is blocked from effectively moving air across the coil, your system can overload and trip the circuit breaker.

Insufficient Refrigerant Charge

If the AC refrigerant charge is low, your air conditioner will work beyond its normal limits to try to keep the thermostat happy. This can be the reason the A/C is tripping the circuit breaker, and it also indicates that your system has a refrigerant leak that needs attention.

Other Malfunctions

Problem with fans, motors, capacitors and other mechanical and electronic parts in the A/C system can lead to high current demands and tripped circuit breakers.

If your Natchitoches home is hot and uncomfortable because the A/C is tripping the circuit breaker, call Pioneer Comfort Systems at 318-795-8000 for quick, courteous A/C service.
