Glossary of Terms
- Circuit Breaker: A safety device designed to automatically stop the flow of electricity in a circuit as a protection against overloads or short circuits.
- Refrigerant: A substance used in the cooling mechanism of an air conditioner to absorb and release heat, facilitating the cooling process.
- Compressor: The component in the AC system that compresses the refrigerant and circulates it through the coils to release absorbed heat outside.
- Evaporator Coils: The part of the air conditioner that absorbs heat from the air inside your home, aiding in the cooling process.
- Condenser Coils: Located in the outdoor unit, these coils release the absorbed heat outside, completing the cooling cycle.
Common Causes of AC Breaker Trips
Several factors can cause an air conditioner to trip the breaker. Identifying these issues early can help prevent further complications. Here are some common reasons:
Dirty Air Filters: Clogged air filters restrict airflow, forcing the system to work harder to circulate air throughout your home. This added strain can cause the system to overheat, leading to frequent breaker trips. Regularly replacing or cleaning your air filters can prevent this issue and ensure optimal airflow.
Refrigerant Leaks: Low refrigerant levels often lead to the compressor overworking, which can trip the breaker. Refrigerant leaks not only compromise the efficiency of your system but can also damage the compressor over time. It’s crucial to have a professional HVAC technician detect and fix any refrigerant leaks to maintain your system’s efficiency and prevent potential damage.
Faulty Components: Malfunctioning parts, such as the compressor, motor, or capacitor, can lead to electrical issues that cause the breaker to trip. These components are essential for the proper functioning of your AC system, and any faults can result in system inefficiencies and potential damage. Professional assessment and repair of these components are often necessary to restore your system’s functionality.
Overloaded Circuit: In some cases, the AC unit shares a circuit with other high-power devices, which can overload the circuit and trip the breaker. Ensuring that your AC unit has its dedicated circuit can help resolve this issue and prevent future breaker trips.
Short Circuits: Electrical shorts within the AC system can cause a sudden surge of electricity, tripping the breaker. This is a serious issue that requires immediate attention from an HVAC professional to prevent potential hazards.

Troubleshooting Tips for Homeowners
Before calling a professional, there are several troubleshooting steps you can take to address the issue:
Check the Air Filter: Start by inspecting the air filter. If it’s dirty, replace or clean it to improve airflow and reduce strain on the system. Regular filter maintenance is a simple yet effective way to prevent many common AC issues.
Inspect the Thermostat Settings: Ensure that the thermostat is set correctly and hasn’t been accidentally changed. A misconfigured thermostat can cause the system to run inefficiently and potentially trip the breaker.
Look for Blockages: Check for any obstructions around the outdoor unit that could impede airflow. Clear away any debris, plants, or other obstacles to ensure proper ventilation and system efficiency.
Reset the Breaker: After addressing any obvious issues, try resetting the breaker. If it trips again, it’s a sign of a more serious problem that requires professional intervention.
Listen for Unusual Noises: Pay attention to any strange noises coming from the unit, as these can indicate component issues, such as a failing motor or loose parts. Identifying these signs early can prevent more significant damage and costly repairs.
Regular maintenance can prevent many common AC issues. Consider signing up for our Maintenance Agreement for scheduled check-ups and peace of mind.
When to Call a Professional
While some issues can be resolved with simple troubleshooting, others require the expertise of a trained HVAC technician. Here’s when to call in the pros:
Repeated Breaker Trips: If the breaker continues to trip after basic troubleshooting, it’s time to call a professional. Persistent breaker trips indicate underlying issues that need expert attention.
Refrigerant Issues: Only a licensed technician should handle refrigerant, so contact a professional if you suspect a leak. Handling refrigerant without proper training can be dangerous and lead to system damage.
Electrical Concerns: Issues like short circuits or faulty wiring should be addressed by an expert to ensure safety and prevent electrical hazards. Professional technicians have the knowledge and tools necessary to safely resolve these issues.
Unresolved Component Failures: If you suspect a component issue, such as a faulty compressor or motor, professional assessment and repair are necessary to restore your system’s functionality.
