McQuay commercial HVAC service in San Diego County
Precision Air Inc works with businesses, property managers and facility teams across San Diego County to service, repair and maintain McQuay equipment: chillers, rooftop and air handlers.
McQuay equipment we work on
McQuay is the older name for equipment now sold as Daikin Applied, and a lot of McQuay chillers, rooftop units and air handlers are still running on commercial buildings.
Repair or replace?
McQuay equipment is no longer sold under that name, but much of it can still be serviced. When parts or efficiency stop making sense, we'll go over replacement options and help you plan the change around your building's schedule.
Repair and service calls
We diagnose the actual failure, whether it's controls, compressors, motors, belts, burners or refrigerant, explain it in plain terms and give you an honest, upfront quote before work begins. Office hours are Monday–Friday, 8 am–5 pm. After hours, our answering service takes your message and our office follows up the next business day.
Preventive maintenance
Regular maintenance cuts down on surprise shutdowns. We set up a schedule that fits your equipment and building. See commercial HVAC and maintenance plans.
