Engineered Air Service in Phoenix, AZ
Custom air handlers and direct-fired make-up air from Calgary, working in Phoenix warehouses and plants.
Engineered Air builds custom air-handling units and direct-fired make-up air equipment in Calgary, and its DJ Series direct-fired units are a familiar sight on the roofs of Phoenix warehouses, manufacturing plants and industrial buildings, where large volumes of tempered outside air are needed to replace process and general exhaust. The company's custom air handlers serve institutional and commercial buildings across the Valley. Bleuwave services Engineered Air equipment as an independent contractor, without factory affiliation.
Direct-fired make-up air is a specific discipline. The burner fires directly into the airstream, which makes the equipment efficient and simple, and which also makes combustion safety, gas-pressure control and airflow proving non-negotiable service items. Custom air handlers are serviced from the drawings, as all engineered equipment should be.

DJ Series and Custom Air Handlers
DJ Series units are direct-fired make-up air and heating units for industrial ventilation: outside air is drawn through a burner section and delivered tempered to the space, replacing exhaust and, in winter, heating large open buildings. Configurations include evaporative cooling sections for summer — a natural fit in Phoenix — and controls that interlock with exhaust systems. Engineered Air's custom air handlers cover indoor and outdoor units with the full range of coil, filter, fan and damper sections for commercial and institutional applications.
Service in Phoenix
DJ units on Phoenix industrial roofs face dust loading of intake filters and burner sections, seized intake dampers, evaporative-section scale and media failure from hard water, gas-train component wear and, on the safety side, flame-safeguard and airflow-proving faults that must be verified rather than reset. Custom air handlers show the Valley's standard wear: fouled cooling coils, loaded filters, seized dampers, fan and drive wear.
Every direct-fired service includes combustion verification, gas-pressure check, flame-safeguard test and airflow-proving verification. Repairs cover burners, gas valves, controls, dampers, fans, evaporative sections and filters. Custom air handlers are assessed against design values and restored — coils, fans, dampers, controls — within sound casings, with replacement quoted where the unit no longer fits the building.
Straight Answers
Questions About Engineered Air Equipment
Our DJ unit will not fire. Can you service direct-fired equipment?
Yes. Direct-fired make-up air units are within our heating and ventilation practice, including gas-train, flame-safeguard and airflow-proving diagnostics. We verify combustion safety on every service, not just when a fault occurs.
Does an evaporative cooling section on a make-up air unit make sense in Phoenix?
Yes, for warehouses and industrial spaces. It cools large volumes of outside air inexpensively for most of the summer, with reduced effectiveness during monsoon humidity. Water management is essential to keep the media from scaling.
Is Bleuwave affiliated with Engineered Air?
No. We service Engineered Air equipment as an independent contractor without factory affiliation or authorization.
