A breaker may keep tripping on an HVAC system for several reasons, including:
Overloaded Circuit: If the HVAC system is drawing too much power from the circuit, the breaker will trip to prevent overheating and potential fire hazards. This can be caused by too many appliances or devices running on the same circuit or an HVAC system that is too large for the circuit.
Short Circuit: If there is a short circuit in the wiring or electrical components of the HVAC system, the breaker may trip to prevent damage to the equipment or potential electrical hazards.
Dirty Air Filter: A dirty air filter can cause the HVAC system to work harder than it needs to, which can lead to an overload on the circuit and trip the breaker.
Faulty Components: Faulty electrical components, such as a malfunctioning compressor, fan motor, or capacitor, can also cause the breaker to trip.
If your breaker keeps tripping, it is important to address the issue promptly to avoid potential hazards and damage to your HVAC system. You should call a licensed HVAC technician to diagnose and repair any problems with your system. They may need to replace faulty components, clean or replace air filters, or upgrade the electrical circuit to accommodate the system’s power requirements.
