Services · the Phoenix metro

Four services, one standard: measure first, then propose.

Commercial only. Every proposal starts with a load calculation or a site survey, because the unit that was there is not always the unit the building needs.

Design-build HVAC

Mechanical design-build for commercial new construction and tenant improvement: load calculations, equipment selection, stamped drawings, energy code compliance, ductwork, piping, controls and commissioning, all under one contract.

Rooftop unit replacement

Rooftop unit replacement for offices, retail and industrial buildings: the unit sized to the building rather than to the old nameplate, the crane and street closure handled, and the new unit running by end of day with the controls tied in.

03 — Facility managers and owners

Controls and energy

Building automation systems installed and tuned, existing systems retro-commissioned, and energy retrofits with the savings measured on the bill rather than promised in a brochure.

04 — Property managers and facility directors

Maintenance agreements

Preventive maintenance for commercial HVAC: quarterly visits by NATE-certified technicians, measured readings on every unit, photos, a ranked list of what is coming, priority emergency response and a 24-hour line for contract clients.

05 — Questions

Before you call.

Do you do residential?

No. Commercial buildings only: offices, medical, retail, restaurants, industrial and schools.

How fast can you replace a failed rooftop unit?

For common sizes in stock locally, within a week including the crane and permit. In peak summer, contract clients come first.

Do you provide a load calculation?

On every replacement and every design-build project. It is in the proposal, and we show the sizing.

Can you take over maintenance on equipment you did not install?

Yes. We survey every unit first and give you a condition report before pricing the contract.

Next step

Tell us about the building. We will come measure it.

A project manager replies the same business day. Maintenance clients reach a technician on the 24-hour line.
