Greenheck DOAS, Make-Up Air & Fan Service in Phoenix, AZ
The fan on the roof, the damper in the wall and the outside-air unit feeding the building. Greenheck is in nearly every Phoenix commercial building somewhere.
Greenheck is the largest manufacturer of commercial air-movement equipment in North America, and it would be difficult to find a Phoenix commercial building without something Greenheck in it: exhaust fans on the roof, kitchen hood fans, louvers and dampers in the walls, and increasingly the dedicated outdoor-air and energy-recovery units that condition the building's ventilation air. The company's DGX direct-fired and IGX indirect-fired make-up air units serve kitchens and industrial spaces. Bleuwave services Greenheck equipment as an independent contractor, without dealer affiliation or factory authorization.
Ventilation equipment in Phoenix is where the money goes quietly. Outside air at 115 degrees is the most expensive air to condition, and a DOAS unit with a fouled energy-recovery wheel, or a make-up air unit with a stuck damper, costs a building far more than the repair. Fans and dampers fail invisibly until a kitchen goes negative or a restroom smells; a maintenance program that includes the air-movement equipment catches them first.

Greenheck Equipment in Phoenix
RV and RVE dedicated outdoor-air units condition 100 percent outside air with energy-recovery wheels and DX or chilled-water cooling for schools, offices and medical buildings. DGX and IGX make-up air units replace kitchen and industrial exhaust with tempered air. Energy-recovery ventilators pre-condition outside air with exhaust-air energy. Roof and wall exhaust fans, kitchen exhaust fans, supply fans, louvers and control dampers — the equipment most people never see — move and control air throughout the building.
Phoenix Wear Patterns
Energy-recovery wheels foul with dust and lose effectiveness; their drive belts and motors wear. DOAS cooling coils and DX condensers face the extreme outside-air load. Direct-fired make-up air units accumulate dust in burner sections and need combustion and airflow-proving verification. Kitchen exhaust fans load with grease and vibrate their bearings and mounts apart; their hinged bases and grease containment need attention. Dampers and actuators seize from dust and disuse. Fan motors, belts and bearings on rooftop exhaust fans wear through continuous duty in the sun.
Service, Repair and Replacement
We service DOAS and make-up air units for airflow, energy-recovery performance, coil and condenser condition, combustion safety and controls; kitchen exhaust fans as part of commercial kitchen ventilation service; and fans, dampers and actuators as part of building air-balance and pressurization work. Repairs cover wheels, motors, belts, bearings, burners, coils, dampers, actuators and controls. Replacement is sized to the building's current ventilation requirement — occupancy, exhaust and code — rather than the old nameplate.
Straight Answers
Questions About Greenheck Equipment
Do you service Greenheck kitchen exhaust fans?
Yes — bearings, belts, motors, hinged bases, grease containment and vibration — as part of our commercial kitchen ventilation practice.
Our Greenheck DOAS unit does not seem to help on hot afternoons. Why?
Usually a fouled or stopped energy-recovery wheel, a struggling cooling coil or condenser, or a controls sequence that is not modulating outside air to occupancy. We measure the unit's performance against design and correct the cause.
Is Bleuwave a Greenheck representative?
No. We service Greenheck equipment as an independent contractor without dealer affiliation or factory authorization.
