Reznor: Over a Century of Commercial & Industrial Heating Excellence

Reznor is one of the most recognized names in commercial and industrial HVAC, with a heritage stretching back to 1888. Founded by George Reznor in Pennsylvania, the company began by pursuing better everyday comfort and safety — a mission that evolved from gas lighting into the rugged, precision-engineered heating systems the brand is known for today. That foundation of innovation led to landmark achievements, including pioneering the first gas-fired unit heater in the United States in 1920 and the first gas-fired industrial heater in 1935.

Today, Reznor designs and manufactures a comprehensive lineup of gas-fired unit heaters, duct furnaces, electric unit heaters, air handlers, and specialty heating equipment for commercial, industrial, and agricultural environments. Their products are engineered for demanding applications — warehouses, manufacturing facilities, garages, agricultural buildings, and more — where dependable, year-round thermal comfort directly affects worker productivity and operational efficiency.

What sets Reznor apart is the depth of their product ecosystem. Beyond complete heating systems, Reznor supports long equipment lifecycles with a robust catalog of genuine OEM replacement parts. Draft inducer motors and vent parts keep combustion venting safe and efficient. HVAC blower motors maintain proper airflow across unit heaters and duct furnace applications. Precision gas valves and controls regulate fuel delivery for reliable ignition and consistent heat output. HVAC control modules and ignition boards form the electronic backbone of Reznor's direct-spark ignition systems, while pool and unit heater parts round out the parts portfolio for specialty and commercial heating applications.

Because Reznor equipment is built to last well beyond its warranty period, investing in genuine OEM replacement components is one of the most cost-effective ways to extend the life of an existing system. Whether you're a licensed HVAC contractor servicing a large industrial facility or a facilities manager maintaining a fleet of unit heaters, Reznor's parts catalog covers a wide range of current and legacy models — from the popular UDAP and UDBP series to older OB and OH units.
