Commercial Rooftop Units in Park City—Install, Repair & Maintain Your Unit With Premier Strand
Rooftop units are the workhorse of commercial HVAC in Park City. They heat and cool restaurants, lodges, retail storefronts, and office buildings across Summit County—and when one goes down during ski season or a summer event weekend, the impact is immediate. Premier Strand Heating & Air has been servicing commercial rooftop units since 1985. Our certified technicians understand the altitude-specific demands that RTUs face at 7,000 feet: UV degradation of electrical components, refrigerant pressure variance, snow load stress on housings and curbs, and combustion calibration requirements that differ significantly from sea-level installations. Call (385) 327-0381 for a free estimate or to schedule emergency service—we are available 24/7.
Expect Expert Care: Our Commercial Rooftop Unit Process
- Site assessment: We evaluate your rooftop unit’s condition, curb integrity, electrical supply, and ductwork connections before recommending repair or replacement.
- Altitude-adjusted sizing: For new installations, we perform load calculations specific to your building’s square footage, occupancy, and elevation—not manufacturer sea-level defaults.
- Scheduled or emergency dispatch: Most repair calls are dispatched same-day. Installations are typically completed in one to two days depending on unit size and curb requirements.
- Combustion and refrigerant calibration: Every RTU we install or service is calibrated for Park City’s altitude before we leave the roof.
- Post-service documentation: We provide a written service report on every call—useful for warranty records, property management logs, and capital planning.
Why RTU Service at Altitude Requires a Expert Commercial HVAC Services
Commercial rooftop units installed or serviced without altitude adjustments run inefficiently, cycle more frequently, and fail sooner than properly calibrated equipment. At Park City’s elevation, refrigerant charge targets, gas valve pressure settings, and airflow calculations all deviate from the specifications printed on the unit nameplate—and a technician working from sea-level defaults will leave your system underperforming from day one. This isn’t just a “nice-to-have” service. In fact, the U.S. Department of Energy’s guidance on commercial heating efficiency consistently identifies correct installation and calibration as the primary drivers of long-term operating cost. Premier Strand applies that standard to every RTU job in Summit County.

Common Commercial Rooftop Unit Problems We Solve in Park City
