Your air conditioners are just one of many different components in your electrical grid. These units have a set of multiple parts, from ducts, filters, and other interior and exterior pieces that regulate your indoor temperatures. Unfortunately, this relatively large appliance can occasionally have disagreements with your circuit breaker. Since an AC uses a considerable amount of electricity, it’s not uncommon for your AC to be the cause of tripped circuit breakers.

How are AC Units and Circuit Breakers Connected?

When your circuit breakers sense an oncoming burst of electricity, it automatically “trips” to prevent your building’s electrical circuits from completing. Although it can seem like an inconvenience, it’s actually a self-defence mechanism to avoid damaged appliances or electrical fires. If you believe your AC is at fault for your circuit breaker’s constant breaking, you must understand what factors contribute to its use of too much energy.

In this article, we’ll share three potential reasons your AC is tripping your circuit breaker.

1. Clogged Internal and External Units

Once your AC’s air filter becomes full of dirt, it will have more difficulty maintaining temperature levels with the same energy usage. Too much blockage will cause your AC to work overtime, forcing proper air circulation to draw in more power than necessary. Besides compromising your circuit breaker, you’ll also be inhaling unfiltered air.

Although many people would identify their AC’s air filter as a cause for overheating, external blockages are also common. The external unit can become filthy, which causes dispersing the heat from your interiors will be much harder. Since dirt can act as an insulator, the AC can run longer and harder to force heat to the outside. This will also lead to increased electrical current to overcompensate. For this reason, it’s vital to check both interior and exterior units for any damaging blockages.

2. Damaged AC Electrical Motor

Like any appliance, an AC unit can burn out through consistent use. An overheated electrical motor can cause an electrical short if it does not receive a break after long periods. Even if you don’t use your AC for too long, your AC system can still overheat sooner if you use it during hot seasons.

3. Compromised AC Compressor

Your AC’s compressor can act up if it has issues drawing in electricity. This usually happens due to an ageing AC system. Since older units have more wear and tear, it’s most likely that wiring issues and other components can start popping up.

Besides your AC compressor’s age, it can also be grounded due to compromised electrical wiring. A grounded compressor can occur in new and old AC systems and can ignite the oil it contains to achieve faster heating. This is why your circuit breaker detects a potential threat and shorts itself. You’ll need a professional AC technician to replace your compressor and assess the full extent of the damage.


Having a working AC is vital to keep you comfortable during harsh summer seasons. For this reason, it’s necessary to prevent any complications with it and your circuit breaker. If your circuit breaker keeps on tripping due to your AC, you may need a reliable AC expert to provide solutions.
