Commercial HVAC Equipment
Commercial HVAC Equipment We Service in Phoenix, AZ
Fifteen categories of equipment, from the packaged unit on a strip-center roof to the chiller plant under a hospital. Each page explains what the equipment is, what Phoenix does to it, and how we approach repair and replacement.
How to Use This Section
Start With the Nameplate.
Commercial HVAC is not one thing. A rooftop unit fails differently from a water-source heat pump, a cooling tower needs a different maintenance calendar from a boiler, and a VRF system is diagnosed from a controller rather than a gauge. The pages below are organized by equipment category so a facility manager can find the equipment on the roof, in the mechanical room or above the ceiling, and read what actually matters about it in this climate.
Each category page covers how the equipment is applied, what a Phoenix summer does to it, the symptoms that bring us out, the repair-versus-replace decision, and the manufacturers we most often encounter. For the brand on your equipment, see the manufacturer directory. For the decision itself, see repair or replace.
