What is an HVAC Contactor?

Within the HVAC system, the contactor is a critical link that controls the smooth transfer of electricity between various internal components of the air conditioner. By providing a clear pathway for efficient electrical flow, the contactor helps prevent potential damage and ensures an uninterrupted operation.

How Does an HVAC Contactor Work?

When your AC is turned off, the contactors are up and blocking the electricity from reaching the major components like the condenser, compressor and motors. They then lower to allow the electricity to pass when the unit is on. This ensures that you can save power in the long run and your unit can get a break when not in use.

What are Signs of a Failing HVAC Contactor?

Common indicators of a failing contractor can be anything from visible damage like melted or charred casings or audible signs like chattering or humming. This can happen if the coils come loose. Also, if the AC unit has issues with turning on or off, it could point to a faulty contactor. When faced with these warning signs, it’s important that you replace the HVAC contactor in a timely manner.

Can a Faulty Contactor Cause System Issues?

Absolutely. If your AC unit has a malfunctioning contactor, the unit can present various problems. These can encompass failure to start properly or at all, insufficient cooling or ongoing operation despite the thermostat being turned off.
