Whenever the A/C is tripping the circuit breaker, it is a sign that the system needs immediate attention. Circuit breakers shut themselves off whenever they sense an electrical short, or build too much heat. This buildup can be caused by a brief, excessive amount of electricity flowing through the circuit. Look for discoloration around the breaker or a burnt smell. If any of these conditions are present, have it inspected by a licensed electrician as soon as possible.
A dirty air filter might cause the circuit breaker to trip, since the equipment has to work harder. It is a good idea to check the filter monthly, or change it regularly during the peak of the cooling season to keep energy consumption low, and for optimum performance.
The condensing coil in the outdoor condenser may be dirty, or the condenser unit could be blocked by excessive vegetation or dust. Remove anything within three feet of the condenser and hose off the coil and its fins, using a gentle spray.
When to Call a Professional
When the A/C is tripping the circuit breaker, one of the first things an HVAC pro checks is the amount of refrigerant. Low refrigerant increases the work load on the equipment, increasing its energy consumption. Another telltale sign of low refrigerant is a frozen indoor coil. Once the coil or refrigerant line leaks are fixed, the technician will add the precise amount of refrigerant your system requires.
Faulty condenser fans, and a damaged electrical component (especially the capacitor for the compressor), can trip the circuit breaker. Central A/C units require a lot of electricity, most of which is used by the compressor.
