Pressure Switches

HVAC pressure switches are safety and control components used to verify proper airflow, draft, and system pressure before and during operation. NWF Supply offers a selection of OEM and OEM replacement pressure switches compatible with major HVAC manufacturers including Nordyne, Frigidaire, Lennox, Trane, and York.

These pressure switches are commonly used in gas furnaces, packaged units, and air handlers to monitor inducer operation, venting conditions, and system safety circuits. All replacement switches are matched to original equipment specifications for pressure rating, electrical configuration, hose connection size, and mounting style to ensure proper system operation and reliable safety performance.

Our inventory includes direct-replacement HVAC pressure switches designed for accurate sensing, consistent operation, and dependable performance in residential and light commercial HVAC applications.
