Reznor Unit Heater & Make-Up Air Service in Phoenix, AZ
The other name on the warehouse ceiling, and the make-up air unit on the plant roof.
Reznor has built gas-fired heating equipment since the nineteenth century and is, with Modine, one of the two names most often found on unit heaters in Phoenix warehouses, shops, distribution centers and industrial buildings — UDX power-vented units, UEZ and UEAS high-efficiency and separated-combustion units, WS hydronic units. The company's YDMA direct-fired make-up air units and MAPS packaged rooftops serve buildings with heavy ventilation loads. Reznor operates within Nortek Global HVAC. Bleuwave services Reznor equipment as an independent contractor, without dealer affiliation or factory authorization.
Unit heaters in Phoenix fail from idleness; make-up air units fail from dust. Both need pre-season service — the heaters before December, the make-up air units before the summer they spend pulling 115-degree air through their filters and burner sections.

UDX, UEZ and UEAS gas-fired unit heaters across the commercial and industrial range, with power venting and separated-combustion options; WS hydronic unit heaters on boiler systems; duct furnaces and infrared radiant tube heaters; YDMA direct-fired make-up air units delivering large volumes of tempered outside air; and MAPS packaged rooftops combining make-up air, cooling and heating for restaurants, plants and other high-ventilation buildings.
Service in Phoenix
Unit heaters show idle-season failures — fouled burners, failed igniters and flame sensors, stuck gas valves, seized fans, tripped pressure switches — and the heat-exchanger cracks that make first-fire combustion verification essential. Make-up air units accumulate dust in filters and burner sections, seize intake dampers and need combustion, gas-pressure, flame-safeguard and airflow-proving verification. MAPS rooftops carry the extreme outside-air load on their cooling sections. Every service includes safety verification and combustion analysis; repairs cover ignition, gas valves, controls, fans, exchangers, dampers, burners and cooling components; replacement is straightforward on unit heaters and engineered to the ventilation requirement on make-up air and MAPS equipment.
