Pressure Switches
HVAC pressure switches are a control device used in HVAC systems that are crucial to its safe operation. Because of this, it’s important to inspect pressure switches during seasonal maintenance and replace them if they are triggering false shutdowns or fail to respond to pressure changes. Dust, moisture, and vibration can also affect the performance of a pressure switch over time, so look out for those signs as well....Read more
Pressure switches monitor air or refrigerant pressure and trigger responses based on set thresholds. They’ll monitor static pressure, differential pressure, and refrigerant pressure to verify their safe operation, and then activate or deactivate components like fans, burners, or compressors based upon the pressure readings. This serves to ensure proper airflow, combustion, or refrigerant flow through changing pressure conditions.
HVAC pressure switches prevent unsafe operation due to block vents, low airflow, or refrigerant issues, so they’re often necessary to help meet building code compliance. They also ensure the systems operate effectively, saving on energy costs and protecting sensitive HVAC components from overpressure or underpressure damage.
