In April 2025, the owner of a boutique gift shop in the 9th and 9th commercial district contacted us about an aging rooftop unit serving her shop. The 1923 commercial-residential mixed-use building on 900 South had received various HVAC modifications over the years; the second-floor residential apartment had been served by a separate gas furnace replaced in 2018, but the ground-floor commercial space had retained its 1996 Lennox 3-ton rooftop unit (29 years service age) that was producing inconsistent cooling and audible compressor strain. Marcus Halverson evaluated the property and identified an interesting challenge: replacement of the rooftop unit required coordination with both the shop owner (downstairs commercial tenant) and the residential tenant upstairs (concerned about work noise during installation). Solution: project scheduled for a Tuesday-Wednesday in late April when shop traffic typically lighter and residential tenant working from home was able to relocate temporarily. Replacement: Carrier 50TC*A07 Performance series 6-ton rooftop unit (larger than original to accommodate evolved cooling demand from commercial space additions of computer equipment, lighting, and refrigeration display cases over 29 years). Marcus + Eli Tran completed 2-day installation including Wasatch Front Crane Service crane operation for unit removal and replacement, new electrical service connections, refrigerant lineset modifications, control system upgrades. Total cost $18,400 installed; net cost reduced by Federal IRA 25C credit application for commercial property (consult tax professional). Shop reopened Thursday morning with significantly improved cooling capacity and reliability. 9th and 9th’s combination of historic mixed-use commercial properties, eclectic neighborhood character, and active boutique commercial district creates distinctive HVAC service patterns we specialize in.
The opening scenario represents 9th and 9th’s commercial service market. The 1923 mixed-use building pattern (commercial ground-floor + residential upstairs) creates distinctive service patterns: separate HVAC systems per use, coordination between commercial tenant and residential tenant, work scheduling around commercial business hours, crane equipment requirements for rooftop unit work. Wasatch Front Crane Service partnership essential for our commercial RTU work; their crane positioning expertise supports efficient rooftop unit replacements. Carrier 50TC Performance series mid-tier commercial RTU equipment serves these mixed-use buildings reliably.
Recent project: 1924 Craftsman bungalow near 1100 East and 1000 South, first-time central AC installation. Existing 2014 Bryant 925SA furnace with variable-speed ECM blower compatible for cooling integration. Bryant 24ACA336A003 2-ton 14 SEER2 outdoor unit + Bryant CNPVP3024 evaporator coil + Honeywell T6 Pro smart thermostat + new 30-amp 240V electrical circuit + 26-ft insulated refrigerant lineset routed through basement utility area + condensate drainage to basement floor drain. $11,800 installed; $10,200 net after $400 Wattsmart + $1,200 IRA 25C. Customer (architect) prioritized aesthetics: outdoor unit placed in concealed rear yard, electrical conduit painted to match brick masonry, condensate drain line concealed within basement. Architectural attention to detail matched 9th and 9th customer expectations effectively.
The 9th and 9th commercial district includes 15+ restaurants with substantial commercial HVAC requirements: kitchen exhaust ventilation, makeup air systems, dining room cooling and heating, ventilation balancing for combustion appliances and exhaust hoods. Recent project: locally-owned bistro on 900 South, ongoing service relationship since 2019 covering: kitchen exhaust hood maintenance, restaurant HVAC tune-ups twice annually (spring and fall), restaurant equipment service coordination, after-hours service for restaurant emergency situations. Annual maintenance contract $1,400 covering: quarterly HVAC inspections + 4 filter changes + makeup air system service + kitchen hood ductwork cleaning. Restaurant service requires understanding commercial kitchen ventilation patterns, NFPA 96 commercial kitchen ventilation code, balanced HVAC operation supporting both customer comfort and kitchen ventilation requirements.
Recent project: 1918 mixed-use building on 900 South, comprehensive HVAC service across building. Property includes: ground-floor specialty retail shop (separate Carrier RTU), 2nd floor 2-bedroom apartment (separate gas furnace + AC), 3rd floor 1-bedroom apartment (separate ductless mini-split system). Building owner contracted for annual maintenance covering all three HVAC systems: $1,800 annual contract = $600 per HVAC system covering bi-annual tune-ups + priority emergency dispatch + 15% repair discount. Mixed-use building economics support this approach: owner manages three separate HVAC systems across single building, single contractor relationship simplifies coordination, predictable annual cost across complex property.
9th and 9th’s customer base includes architects and design professionals frequently designing custom homes or major renovations with comprehensive HVAC requirements. Recent project: 2024 substantial renovation of 1928 bungalow on Mclelland Street (Liberty Wells boundary). Architect-designed project including: Mitsubishi Hyper-Heat ductless multi-zone system serving expanded floor plan (4-zone configuration), comprehensive whole-home humidification (AprilAire 700), comprehensive IAQ (Aprilaire 5000 electronic air cleaner), smart home integration (ecobee Premium thermostat + Apple HomeKit integration), Aeroseal duct sealing throughout. $26,800 HVAC scope within larger renovation project. Architect coordination essential for proper HVAC integration with renovation design intent.
9th and 9th-specific pricing factors: typically comparable to SLC standard rates; commercial work pricing reflects commercial equipment requirements.
Federal IRA 25C may apply to commercial RTU replacement when meeting efficiency thresholds; consult tax professional for specific commercial property application. Section 179 immediate expense election may apply for qualifying commercial HVAC equipment. Property tax implications vary; consult tax professional. Rebates from Rocky Mountain Power Wattsmart available for qualifying commercial equipment ($400-1,200 typical for commercial RTU). Specific cost requires property assessment.
We provide flexibility for restaurant scheduling priorities. Long-term restaurant relationships develop including familiarity with restaurant’s operating patterns and seasonal scheduling needs. Annual maintenance contracts include after-hours service capability supporting flexible scheduling.
Pre-renovation HVAC consultation identifies opportunities for integrated planning. We coordinate with general contractors for proper sequencing of HVAC work within renovation timeline.
Our commercial service maintains transparent pricing matched to actual scope and complexity. Commercial customers benefit from contractor expertise in commercial-specific requirements vs. residential contractors attempting commercial work.
