air pressure switch

What is an air pressure switch? An air pressure switch (a.k.a. pressure sensor) is a special tool in your control over how air is moving in the HVAC system. It tests the air pressure and switches on or off the system according to the pressure level that it is set on. The air pressure switch lets the HVAC system operate properly and uses less energy.

How an Air Pressure Switch Regulates HVAC Systems

The importance of an air pressure switch in an HVAC system An air pressure switch plays a crucial role in maintaining the proper temperature and air quality in a building. Once the air pressure achieves a targeted level, the air pressure switch sends a signal to the HVAC system to turn on and begin distributing air. The air inside the compressor continues to build until the predetermined pressure is reached and the air pressure switch turns the system off. This conserves energy and keeps the system from unnecessary effort.
