How much does commercial HVAC maintenance cost in Draper?

A semi-annual commercial maintenance visit for a single gas-electric RTU typically runs $285–$450 per visit, or $520–$850 for the annual pair. Multi-unit buildings are quoted at a reduced per-unit rate for the second and subsequent units. Restaurant RTU quarterly maintenance (four visits per year per unit) typically runs $1,200–$1,800 per unit per year. Service contract clients receive a discount on per-visit pricing versus non-contract maintenance rates.

What is included in a commercial service contract?

Commercial service contracts define the scope of scheduled maintenance visits, the response time commitment for emergency service calls (typically a 4-hour or 8-hour response window for contract clients versus standard scheduling for non-contract clients), and the labor rate structure for repair calls during the contract term. Contract documentation includes a certificate of insurance, scope of work, equipment schedule, and service frequency.

Do you service commercial HVAC for tenant-occupied buildings where the landlord pays for maintenance?

Yes. We work directly with the property management company on scheduling, documentation, and billing, and coordinate access with the tenants. Maintenance reports are formatted for property management records and provided in digital format within 24 hours of each visit.

Can you take over maintenance on commercial equipment that was previously serviced by another contractor?

Yes. Our standard first-visit protocol for equipment we are taking over includes a baseline assessment: combustion analysis to confirm correct altitude derate is applied, refrigerant charge verification, and filter and coil condition assessment to establish the baseline for ongoing maintenance. We document the baseline findings so the ongoing maintenance record reflects condition at the time we assumed service, protecting against any liability for pre-existing conditions.

Commercial HVAC Maintenance in Draper, Utah

Commercial HVAC maintenance in the south Salt Lake Valley serves the same fundamental purpose as residential maintenance — finding the failures before they happen — but the consequences of unplanned failure are operationally distinct. A residential furnace that fails on a January morning is a serious inconvenience and a pipe-freeze risk. A restaurant on Lone Peak Parkway that loses its heating system on a January morning loses service hours until the system is restored, compounding the equipment repair cost with revenue impact. A dental practice that loses air conditioning during a July heat event has cancelled appointments. The business case for preventive commercial HVAC maintenance is measurable in avoided downtime, not just avoided repair cost.

We provide scheduled preventive maintenance programs for commercial HVAC equipment on annual, semi-annual, and quarterly service schedules. Maintenance visits follow the same instrument-based, documented process as our residential service — combustion analysis, refrigerant charge verification, coil cleaning, filter replacement, and written service reports with all instrument readings. The difference is the documentation format (commercial property management records rather than homeowner records) and the scheduling flexibility to accommodate off-hours service for businesses that cannot interrupt operations for daytime HVAC maintenance.

Commercial Maintenance Service Scope

Gas-Electric Rooftop Unit Maintenance

For gas-electric packaged rooftop units, the semi-annual maintenance schedule covers:

Spring Visit (April–May — Pre-Cooling):

Condenser coil inspection and cleaning (cottonwood seed season in May–June is the primary fouling event for RTU condensers in the south Salt Lake Valley; pre-season cleaning before Memorial Day captures the unit before peak cottonwood loading)
Refrigerant charge verification by subcooling (RTUs typically use TXV metering; subcooling target 10–15°F)
Compressor and condenser fan motor amperages against nameplate
Economizer damper operation and minimum position setting (where applicable)
Filter replacement (commercial filters in restaurant and retail applications load significantly faster than residential due to higher particulate environments)
Condensate drain pan inspection and flush
Electrical connections tightened at the disconnect and unit terminal blocks

Fall Visit (September–October — Pre-Heating):

Combustion analysis at all firing stages with Testo 320 (CO air-free target under 100 ppm; any reading above 200 ppm on a commercial RTU triggers shutdown and gas valve inspection before return to service)
Altitude derate verification — manifold pressure measured against altitude-corrected target for installation elevation. Commercial RTUs that have been serviced by other contractors since original installation are sometimes found with gas valve settings returned to sea-level specification after a gas valve replacement; we verify the derate is still applied
Gas pressure at the unit inlet versus Dominion Energy delivery pressure
Heat exchanger visual inspection through burner access panel; borescope on units over 10 years old or where combustion analysis suggests a concern
Inducer motor amperage and bearing condition
Belt tension and condition on belt-drive blower RTUs (common in older commercial units)
Filter replacement
Control board fault code history retrieval on communicating-capable units

Heat Pump RTU and Commercial Split System Maintenance

For heat pump RTUs and commercial split systems, the maintenance scope is similar to the cooling-side RTU maintenance with the addition of:

Heating mode refrigerant performance verification (heating superheat or subcooling depending on refrigerant circuit type)
Defrost cycle operation confirmation
Reversing valve operation confirmed in both heating and cooling modes
Auxiliary or emergency heat operation (electric resistance strips or gas backup) confirmed

VRF System Maintenance

Variable refrigerant flow systems require specialized maintenance procedures aligned with the specific manufacturer’s VRF maintenance protocol. For Mitsubishi City Multi and Daikin VRV systems, maintenance includes:

Refrigerant system pressure verification against system operating map (VRF systems operate at variable pressures depending on the number of indoor units calling for conditioning; diagnosis requires understanding the system’s normal operating range, not a fixed target)
Individual indoor unit filter cleaning or replacement
Drain pan and condensate pump inspection on each indoor unit
Outdoor unit coil cleaning
System error code history retrieval through the Mitsubishi MA Remote Controller or Daikin intelligent Touch Manager interface
Refrigerant pipe insulation inspection on accessible sections

Documentation

Every commercial maintenance visit produces a written service report formatted for property management files. The commercial service report includes:

Property address and unit identifiers (RTU-1, RTU-2, AHU-1, etc. as tagged in the building)
Visit date and technician name and license number
Equipment model, serial number, and approximate installation date for each unit serviced
All instrument readings: combustion analysis (CO, O₂, stack temperature), refrigerant charge (superheat/subcooling), motor amperages, gas pressure, static pressure
Condition rating by system and by major component (Pass / Advisory / Requires Attention / Safety Concern)
Filter replacement documented with filter model and MERV rating
Any findings outside acceptable range with recommended action and cost estimate
For contract clients: copy filed in the client’s maintenance record in our service management system, available for property management reporting

Off-Hours Scheduling

Commercial maintenance visits that would disrupt business operations are scheduled during off-hours at the client’s request. Typical off-hours scheduling: early morning (6–8 a.m. before business opening), evening (after 6 p.m.), or Saturday. Off-hours scheduling for non-emergency maintenance is available for contract clients; the service contract specifies the scheduling preferences. Off-hours maintenance carries a scheduling premium above standard business hours rates, disclosed in the contract or confirmed before scheduling.

Frequency Recommendations

Commercial HVAC maintenance frequency in the south Salt Lake Valley depends on equipment type and operating environment:

Gas-electric RTUs (office, retail, professional services): Semi-annual minimum — one pre-cooling visit (April–May) and one pre-heating visit (September–October). Annual-only is adequate for lightly used equipment in clean operating environments; semi-annual is recommended for equipment serving high-occupancy spaces or environments with elevated particulate loading.
Gas-electric RTUs (restaurant, food service): Quarterly minimum. Kitchen exhaust grease vapor accumulates on condenser coils and in return air paths at a rate that makes quarterly service the defensible minimum for maintaining combustion performance and cooling capacity. Annual or semi-annual maintenance on restaurant RTUs typically produces visibly fouled coils and degraded combustion analysis readings at each visit.
Heat pump RTUs and commercial split systems: Semi-annual (one cooling-side focus, one heating-side focus). Heat pump reversing valve wear, defrost cycle function, and low-ambient heating performance are heating-season-specific; the fall visit is where these are verified.
VRF systems: Annual at minimum, semi-annual for high-density occupancy buildings. VRF systems accumulate error codes from sub-optimal operating conditions that an annual visit catches before they progress to component failures.

Frequently Asked Questions

How much does commercial HVAC maintenance cost in Draper?: A semi-annual commercial maintenance visit for a single gas-electric RTU (spring cooling visit plus fall heating/combustion visit) typically runs $285–$450 per visit, or $520–$850 for the annual pair. Multi-unit buildings are quoted at a reduced per-unit rate for the second and subsequent units. Restaurant RTU quarterly maintenance (four visits per year per unit) typically runs $1,200–$1,800 per unit per year. VRF multi-zone system maintenance (full system service with individual indoor unit inspection) is quoted based on zone count and system complexity. Service contract clients receive a discount on per-visit pricing versus non-contract maintenance rates.
What is included in a commercial service contract?: Commercial service contracts define the scope of scheduled maintenance visits, the response time commitment for emergency service calls (typically a 4-hour or 8-hour response window for contract clients versus standard scheduling for non-contract clients), and the labor rate structure for repair calls during the contract term. Contract documentation includes a certificate of insurance, scope of work, equipment schedule, and service frequency. See our Commercial Service Contracts page for full contract structure details.
Do you service commercial HVAC equipment for tenant-occupied buildings where the landlord pays for maintenance?: Yes, and this is one of the more common commercial maintenance scenarios we encounter: a property management company that maintains HVAC service for multiple tenant-occupied retail or office spaces where the lease specifies that the landlord provides HVAC maintenance. We work directly with the property management company on scheduling, documentation, and billing, and coordinate access with the tenants. Maintenance reports are formatted for property management records and provided in digital format within 24 hours of each visit.
Can you take over maintenance on commercial equipment that was previously serviced by another contractor?: Yes. Our standard first-visit protocol for equipment we are taking over from another contractor includes a baseline assessment: combustion analysis to confirm correct altitude derate is applied, refrigerant charge verification to confirm correct system charge, and filter and coil condition assessment to establish the baseline for ongoing maintenance. We document the baseline findings so the ongoing maintenance record reflects condition at the time we assumed service, protecting against any liability for pre-existing conditions we did not create.
