Transformers

HVAC control transformers are used to step down line voltage to low voltage for safe operation of thermostats, relays, contactors, and control boards. NWF Supply offers a selection of OEM replacement control transformers compatible with major HVAC manufacturers including Lennox, Nordyne, York, Carrier, and Honeywell.

These transformers are designed for use in furnaces, air handlers, and packaged HVAC equipment. All replacement transformers are matched to original equipment specifications for primary and secondary voltage, VA rating, mounting style, and terminal configuration, ensuring reliable power delivery and proper system operation.
