Why Is My HVAC Tripping the Circuit Breaker?

If you notice that your HVAC unit is tripping the breaker, it would be best to consult a professional. There are several reasons why this could happen, and each of them requires unique solutions. 

To give you an idea of what could cause your HVAC system to trip the circuit breaker, Albert Air Inc. takes a look at some of the most common culprits behind this problem.

Overloaded Circuit

When an electrical circuit is overloaded, the breaker trips. This prevents excessive current from traveling through the wiring and causing a potential fire. Situations like these can happen when too many appliances are running off on one circuit. Breakers can also trip when circuits have inadequate wiring for their required load. If your circuit has overly high amperage demands, consider having it upgraded by trained ductless air conditioner installers near me.

Blown Fuse

Replacing a faulty fuse will usually fix this. However, check that it is rated for your specific unit before replacing it. You may also need to upgrade aging wiring or outlets that don’t meet code requirements.

Clogged Air Filter

If your air filter is dirty, it can block airflow and make the motor work harder. A clogged air filter can cause the current to rise and eventually trip the breaker. Regularly replacing your filter every few months helps prevent this from happening. It’s also beneficial for supporting optimal energy efficiency in your system.

Faulty Electrical Components

Inspecting the components in your HVAC system can help rule out any faulty electrical parts. Ductless air conditioner reviews should include checking the circuit board and tracing for burnt connections or loose wires on wiring looms. Pay attention to the switches, outlets and the Carrier evaporator coil too. If you find anything that is malfunctioning, be sure to contact your local HVAC service provider.

Overheating Components

When your HVAC system experiences a partial restriction in airflow, like a clogged filter, the core components could overheat. You might also hear buzzes or smells coming from the unit. Contact an experienced technician immediately if there are any signs of overheating or strange noises.

If your circuit breaker continues to trip every time you run your HVAC, various components may need to be checked. If the problem persists, our experienced technicians at Albert Air Inc. can help. Call us at (714) 526-6368 or complete our contact form to schedule a consultation.
