Commercial HVAC Systems

We Repair & Install

Phoenix commercial properties rely on a range of HVAC system types. Our technicians are trained and experienced on all of them:

Rooftop Packaged Units (RTUs)

The most common commercial HVAC system in Phoenix. RTUs house all components in a single unit mounted on the roof — making them space-efficient and relatively straightforward to service. We diagnose and repair all RTU issues including compressor failures, refrigerant leaks, heat exchanger problems, economizer malfunctions, and electrical faults. We also install new RTUs and handle full unit replacements.

Commercial Split Systems

Larger commercial spaces often use split systems with multiple air handlers connected to central condensing equipment. We service all commercial split system configurations — diagnosing refrigerant issues, blower and coil problems, control board failures, and more.

Multi-Zone & VRF Systems

Variable refrigerant flow systems allow different zones within a building to be heated or cooled independently — ideal for office buildings, hotels, and mixed-use spaces. We diagnose and repair VRF and multi-zone systems including refrigerant circuit issues, zone controller problems, and communication faults between indoor and outdoor units.

Commercial Heat Pumps

Heat pump systems that provide both heating and cooling for commercial spaces. We service all commercial heat pump brands and handle refrigerant, reversing valve, compressor, and control system repairs.

Preventive Maintenance

| Protect Your Commercial Investment

The most expensive commercial HVAC repair is the emergency call that could have been prevented. Commercial systems that run continuously, especially in Phoenix's extreme heat, accumulate wear faster than residential equipment, and deferred maintenance compounds quickly into larger failures.

Regular commercial HVAC maintenance with Western Sky Mechanical includes:

• Full inspection of all electrical components, connections, and controls

• Coil cleaning, condenser and evaporator, for maximum heat transfer efficiency

• Refrigerant level check and leak inspection

• Belt, bearing, and motor inspection on all rotating components

• Economizer and fresh air damper inspection and adjustment

• Filter replacement and airflow verification

• Thermostat and building control system calibration check

• Written service report with findings and recommendations after every visit

We provide commercial maintenance service on a scheduled basis, quarterly, semi-annually, or annually depending on your system and usage. Keeping your equipment serviced regularly reduces emergency repair frequency, extends equipment life, and keeps your energy costs under control.

For food service operations, restaurants, and businesses that depend on refrigerated storage, we also provide dedicated commercial refrigeration repair , walk-in coolers, freezers, display cases, and ice machines, as a separate service.

3. Transparent Proposal

We provide a clear written scope of work and cost before beginning any repair. Commercial jobs are quoted flat, no hourly surprises. You approve the work before we start.

4. Repair, Test & Document

For true around-the-clock coverage on the most urgent calls, our 24/7 emergency HVAC service is available day and night, including weekends and holidays, for any failure that can't wait until the next business day.
