If your air conditioner keeps tripping the breaker, it’s a problem that shouldn’t be ignored. Many homeowners search “why does my AC keep tripping the breaker?” when their system suddenly shuts off and won’t stay running.
A tripped breaker is more than an electrical annoyance—it’s often a warning sign that your AC system is overworking, overheating, or experiencing an electrical issue. Understanding the causes can help you act quickly and avoid serious system damage.
Circuit breakers are designed to protect your home and HVAC system from electrical overloads. When your AC trips the breaker, it’s usually because the system is drawing more power than it should.
Repeated breaker trips indicate an underlying problem that needs attention.
One of the most common causes of an AC tripping the breaker is restricted airflow. Dirty air filters make it harder for your system to move air, forcing components to work harder and draw more electricity.
Restricted airflow can lead to:
Replacing air filters regularly helps prevent electrical strain and AC repair issues.
Outdoor condenser coils release heat from your home. When coils are dirty or blocked by debris, heat can’t escape efficiently, causing the system to overheat.
An overheating AC system may trip the breaker repeatedly to protect itself from damage.
Worn or failing electrical components such as capacitors, contactors, or wiring can cause irregular power draw. These issues often trigger breaker trips as a safety measure.
Electrical problems should always be handled by a licensed HVAC professional.
The compressor is one of the most power-hungry components in an AC system. If it’s failing or struggling to start, it may draw excessive current and trip the breaker.
Compressor issues are serious and require immediate professional AC repair to prevent system failure.
Low refrigerant levels or refrigerant leaks reduce cooling efficiency and force the system to run longer and harder. This extra strain can cause overheating and breaker trips.
Refrigerant issues should never be handled as a DIY fix.
In some cases, the breaker itself may be improperly sized or wiring may be outdated. An undersized breaker can trip even when the AC is functioning normally.
A professional evaluation ensures your electrical system matches your AC’s power requirements.
Ignoring breaker trips can lead to:
A breaker that trips repeatedly is warning you that something isn’t right.
If your AC trips the breaker:
If the breaker trips again, professional AC repair is needed.
