Commercial HVAC Installation in Draper, Utah

Commercial HVAC installation in the south Salt Lake Valley carries the same altitude considerations as residential installation — and they are at least as frequently ignored on commercial projects as on residential ones. A gas-electric packaged rooftop unit installed on a Lone Peak Parkway retail building at 4,500 feet with sea-level gas valve settings is running rich-burn combustion, accelerating heat exchanger fatigue, and delivering less heating capacity than its nameplate BTU rating suggests, just as a residential furnace installed the same way. The commercial building owner or property manager who paid for a 150,000 BTU rooftop unit is receiving approximately 123,000 BTU of altitude-corrected heating capacity — and if the unit was not derated, the heat exchanger degradation rate is tracking toward the 8–12 year failure timeline rather than the 15–20 year commercial service life the specification sheet implied.

We install and replace commercial HVAC systems for light commercial properties in Draper, Sandy, South Jordan, Bluffdale, Riverton, and Herriman. Every commercial installation includes a documented load calculation, altitude-corrected equipment selection and gas valve commissioning, a commercial mechanical permit, and combustion analysis at startup. The same standards we apply to residential work, at commercial scale.

Commercial Applications We Serve

Retail and Restaurant

Retail suites and restaurant spaces on the Lone Peak Parkway corridor, the Bangerter Highway commercial strip, and the 9000–11000 South Sandy commercial area are among our most common commercial installation locations. Restaurant HVAC is technically more demanding than standard retail: kitchen makeup air requirements, exhaust hood coordination, grease accumulation on condenser coils from proximity to kitchen exhaust, and the year-round heating and cooling demand that restaurant operations impose. We assess kitchen exhaust and makeup air requirements as part of every restaurant HVAC installation scope and confirm the selected equipment is rated for the expected outdoor ambient and heat load conditions.

Medical and Dental Office

Medical and dental offices have HVAC requirements beyond standard commercial comfort: specific temperature and humidity ranges for patient comfort and equipment function, filtration requirements for procedure rooms (HEPA-level filtration in some dental operatory applications), and reliability requirements that make extended equipment downtime particularly disruptive. We specify MERV 13 minimum filtration on all medical office commercial HVAC installations and verify that the selected equipment can support the filter’s static pressure requirement at design airflow — the same static pressure verification we perform on residential MERV 13 upgrades, applied to commercial air handler selections.

Professional Office and Mixed-Use

Professional office buildings and mixed-use developments in the Daybreak Village commercial area, the South Jordan 10600 South corridor, and the newer Herriman developments along the Mountain View Corridor are growing commercial HVAC installation segments. These buildings typically have multiple zones on a single HVAC system, and zone control design is part of the installation scope — not an afterthought added after the equipment selection is made. We specify Honeywell or Aprilaire commercial zone control panels where multi-zone coverage is required and size the bypass damper capacity for the minimum single-zone airflow condition from the start.

Light Industrial and Flex Space

Business park flex spaces in the Draper 12300 South corridor, the Sandy industrial district, and the Bangerter Highway business parks combine office and warehouse functions. HVAC design for these spaces requires separate treatment for the conditioned office sections (comfort conditioning) and the warehouse or production sections (industrial unit heaters or high-efficiency gas heating with ventilation cooling or evaporative cooling rather than refrigerant-based cooling in the non-conditioned production area). We assess each flex space’s conditioned versus non-conditioned boundary and design the HVAC system for each section appropriately rather than specifying comfort conditioning for the entire footprint.

Commercial HVAC Equipment

Packaged Rooftop Units (RTUs)

The dominant commercial HVAC equipment type in the south Salt Lake Valley for single-story retail, restaurant, and office buildings. Gas-electric RTUs provide heating through a gas-fired heat exchanger section and cooling through a refrigerant-based condenser coil section in a single rooftop-mounted cabinet. Heat pump RTUs provide both heating and cooling through the refrigerant cycle, eliminating the gas connection requirement for buildings without existing gas service.

RTU brands we install for commercial light commercial applications: Carrier 50XC and 48TM series, Trane Precedent and Voyager series, Lennox LGH and LCH series, York YCH and YZH series. Tonnage range: 2–20 tons for light commercial applications. Altitude correction applies to all gas-fired RTU installations above 4,000 feet; we apply the manufacturer’s published altitude correction to the gas valve manifold pressure during installation and commissioning and document the corrected manifold pressure in the installation report.

Commercial Split Systems

For commercial spaces that are too small for a full RTU or where the building structure does not support rooftop-mounted equipment, commercial split systems (separate outdoor condenser and indoor air handler) provide the same functionality at lower installed cost for 2–5 ton applications. Carrier, Trane, Lennox, and Daikin commercial split lines for light commercial applications. Commissioning follows the same 500-micron vacuum and charge-by-measurement protocol as residential split systems.

Variable Refrigerant Flow (VRF) Systems

For multi-zone commercial buildings requiring individual room-level temperature control without traditional duct systems, variable refrigerant flow (VRF) systems provide a ductless commercial solution. Mitsubishi City Multi, Daikin VRV, and LG Multi V systems support 4–50+ zones from a single outdoor unit with individual indoor fan coil units in each zone. VRF systems are appropriate for medical office buildings, professional office buildings with private offices requiring independent temperature control, and mixed-use buildings where a single ducted system cannot serve the building’s zone diversity. As a Mitsubishi Diamond Contractor and Daikin Comfort Pro dealer, we install and commission VRF systems in the light commercial range.

The Commercial Installation Process

Load Calculation and Equipment Specification

Commercial load calculations follow ACCA Manual J commercial (or ASHRAE 90.1 compliance methodology for buildings where 90.1 applies). We collect:

  • Building geometry and occupancy classification (occupant count, occupant density, activity level)
  • Envelope thermal performance (insulation levels, window area by orientation, commercial glazing type)
  • Internal heat gains (lighting type and density, equipment loads by space type)
  • Ventilation requirements per ASHRAE 62.1 (minimum outside air by occupancy and space function)
  • GPS-confirmed building elevation for altitude correction on equipment selection
  • Design temperatures: ASHRAE 99% heating and 1% cooling for the Draper area adjusted for the specific building elevation

Permitting

Commercial mechanical permits are required in all six cities in our service area. Commercial permits require: licensed mechanical contractor (Utah DOPL HVAC license covers commercial work within our scope), equipment specifications for each unit, ductwork sizing documentation, and plan review in some jurisdictions for buildings over a certain square footage threshold. We handle the permit application, plan submittal where required, and inspection coordination as part of the installation scope.

Installation and Commissioning

Commercial RTU and split system installation follows the same quality standards as our residential work:

  • Equipment installed on level roof curb with manufacturer clearances verified
  • Refrigerant line sets (for split systems) brazed with nitrogen purge and insulated per manufacturer requirements
  • Altitude derate applied to gas valve manifold pressure on all gas-fired units at our service area elevations
  • Combustion analysis (Testo 320) at steady state: CO air-free target under 100 ppm, O₂ 5–9%, stack temperature within specification
  • Refrigerant charge verified by superheat and subcooling (split systems) or by manufacturer’s commissioning procedure (RTUs with factory charge)
  • Static pressure documented across each air handler
  • Thermostat or BAS programming completed per building requirements
  • Commissioning report provided to building owner or property manager

Frequently Asked Questions

How much does commercial HVAC installation cost in Draper?
Commercial HVAC installation cost depends heavily on equipment type, tonnage, and building-specific installation complexity. Indicative ranges for light commercial applications in our service area: a single 5-ton gas-electric RTU with roof curb, electrical, gas connection, ductwork connections, permit, and commissioning typically runs $12,000–$18,000 installed. A 3-ton commercial split system for a single-tenant office suite runs $8,500–$13,500 installed. Multi-zone commercial split or VRF systems for professional office buildings scale with the number of zones and line set complexity; a 6-zone Mitsubishi City Multi installation for a 3,000 square foot medical office suite typically runs $22,000–$35,000. Every commercial installation is quoted with an itemized scope of work.
Do you need special credentials to install commercial HVAC in Utah?
Utah DOPL requires an HVAC contractor license (#11487612-5501) for all commercial HVAC work within the mechanical contractor scope. Commercial installations also require EPA Section 608 certification for refrigerant handling (we hold Universal certification, #608U-2011-318472), and commercial building permits require a licensed contractor of record. We meet all licensing requirements for commercial HVAC work in our service area cities. For VRF systems (Mitsubishi City Multi, Daikin VRV), manufacturer factory training is required to activate extended warranty coverage; our Mitsubishi Diamond Contractor and Daikin Comfort Pro credentials cover this requirement.
Can you coordinate with a general contractor on a new commercial build-out?
Yes. We work on commercial build-out projects as the mechanical subcontractor, coordinating with the general contractor on rough-in scheduling, equipment delivery, and final inspection timing. For tenant build-outs in existing commercial buildings (retail suite build-outs in Lone Peak Parkway or Bangerter Highway shopping centers, for example), we coordinate with the building’s property management company and the tenant’s contractor to confirm the HVAC scope and ensure compatibility with the building’s existing roof curbs, gas distribution, and electrical panel capacity before equipment is ordered.
What is the altitude correction requirement for commercial HVAC in Draper?
The same as residential: 4% capacity and input reduction per 1,000 feet of elevation above sea level, applied per the manufacturer’s published installation table for the specific equipment model. For commercial rooftop units on the Draper valley floor (4,500 feet), the altitude correction reduces rated input by approximately 18%. For commercial buildings on the elevated benches of Sandy or South Jordan approaching 5,000 feet, the correction is approximately 20%. Commercial equipment that is not altitude-derated runs rich, generates elevated CO in the flue gas, and delivers less heating capacity than the rated BTU output on the specification sheet — the same problems as residential, at commercial scale.
