What if My AC Keeps Tripping the Circuit Breaker?

Mar 8, 2022

Is your air conditioning unit tripping the circuit breaker repeatedly? Experiencing this problem can be frustrating, especially during hot summer days. However, rest assured that Alpine Heating & Air Conditioning is here to help you troubleshoot and resolve this issue.

Common Causes of AC Tripping the Circuit Breaker

There are several potential reasons why your AC may be tripping the circuit breaker. Let's explore some common causes:

1. Electrical Overload

An electrical overload occurs when there is too much demand on a circuit, exceeding its capacity. If your AC unit is running on the same circuit as other high-powered appliances, such as refrigerators or microwaves, it can lead to tripped breakers. Consider redistributing your electrical load to prevent overloading the circuit.

2. Dirty Air Filters

Clogged or dirty air filters can restrict airflow, causing your AC unit to work harder and draw more power. This increased power demand can trip the circuit breaker. It's essential to regularly clean or replace your air filters to ensure proper airflow and prevent unnecessary strain on your system.

3. Faulty Capacitors

Capacitors are responsible for storing and releasing electrical energy to the motor. If a capacitor is faulty or weak, it can cause intermittent power fluctuations, leading to the tripping of the circuit breaker. A professional HVAC technician can inspect and replace faulty capacitors, allowing your AC unit to function properly.

4. Refrigerant Leaks

Low refrigerant levels due to leaks can cause your AC system to overwork, resulting in excessive power consumption and circuit breaker trips. It's crucial to have any refrigerant leaks repaired promptly by a qualified technician to maintain the efficiency of your air conditioner and prevent further damage.

5. Compressor Issues

A malfunctioning compressor can put additional strain on your AC system, causing it to draw excessive power and trip the circuit breaker. The compressor is a vital component, and any issues with it should be addressed by a professional technician for proper diagnosis and repair.

Solutions to Prevent AC Circuit Breaker Trips

Now that we've discussed the common causes of AC circuit breaker trips, let's explore some solutions to help prevent this recurring issue:

1. Schedule Regular Maintenance

Regular maintenance by professional HVAC technicians can identify and address potential problems before they escalate. Routine inspections, cleaning, and tune-ups can keep your AC system running efficiently and reduce the risk of circuit breaker trips.

2. Keep Air Filters Clean

Make it a habit to clean or replace your air filters at least once every three months, or more frequently if you have pets or allergic sensitivities. Clean air filters ensure optimal airflow, reducing strain on your AC unit and minimizing the chance of tripping the circuit breaker.

3. Avoid Overloading Circuits

Redistribute your electrical load by plugging high-powered appliances onto separate circuits. This way, your AC unit won't have to compete for power, reducing the likelihood of circuit breaker trips.

4. Address Refrigerant Leaks

If you suspect a refrigerant leak, reach out to a professional HVAC technician for a thorough inspection and repair. Fixing refrigerant leaks will ensure that your AC system operates at peak performance, without overworking and tripping the circuit breaker.

5. Seek Professional Assistance
