What HVAC component helps regulate system pressure?

The pressure switch plays a crucial role in regulating system pressure within HVAC systems. Its primary function is to monitor the pressure levels in the system and ensure that they remain within safe and operational ranges. When pressure deviates from the desired levels, the pressure switch can signal the compressor or other components to shut down or activate, thus helping to prevent damage due to extreme pressure fluctuations.

This regulation is vital for maintaining efficient operation and preventing system failures. By continuously monitoring the pressure, the pressure switch contributes to the overall stability of the HVAC system, allowing it to operate effectively and efficiently while ensuring user safety.
