A small part, a big HVAC role

The compressor and the condenser may get lots of attention, but your HVAC will fail without small parts like contactors.

They’re the gatekeepers for the electricity that powers your HVAC system. 

When the contactors get the command from the thermostat they drop into the “down” slot to allow your AC to run. Then they rise up and shut off the power when the thermostat signals that the system has generated enough cool air.

This frequent up-and-down activity can take a toll, causing contactors to burn out or to get stuck in one spot. Dirt also can make them malfunction, which is why contactors are on every smart technician’s maintenance list.

Contactor problems can cause a system shutdown and other damage. Remember, they involve electricity, so call a technician to resolve the problem.
