About HVAC Pressure Switches

The HVAC pressure switch is a safety mechanism installed on the air conditioning system's high and low sides.

HVAC pressure switch significance

The HVAC pressure switch is vital because it checks the pressure of the refrigerant on its corresponding side of the system. The high and low side pressure switch both help keep track of the system for pressure malfunction that can damage the compressor. The HVAC pressure switch is significant to the service life and function of the AC system, and the pressure switch keeps the pressure from going too high or low, which can damage the system.

Common issues with a faulty HVAC pressure switch

A faulty HVAC pressure switch can cause the AC system to cut on and off, the compressor will not operate properly, or the system will have trouble keeping the cabin cool.
