What we install
From a single rooftop unit to the full mechanical scope
Commercial installation is scope work: the equipment is only part of it. A rooftop unit needs a curb that fits, a crane that can reach, electrical sized for the new nameplate, duct that delivers the design airflow, controls that talk to the building, and paperwork that satisfies the inspector and the energy code. We carry the whole scope, and we coordinate it with the general contractor’s schedule rather than around it.
Typical projects are rooftop package-unit replacements on retail and office buildings, split systems and heat pumps for suites, VRF/VRV systems for offices and medical spaces, ductwork rework for tenant improvements, and the mechanical scope on new small and mid-size commercial buildings and multi-unit residential.
Scope we take on
- Rooftop package units (gas/electric and heat pump), including crane lift and curb adapters
- Split systems and heat pumps for suites, offices and small buildings
- VRF / VRV multi-zone systems for offices, medical suites and hospitality
- Ductwork design, fabrication coordination and installation
- New-construction HVAC scope from rough-in through startup
- Tenant improvements: rework existing systems for new layouts and loads
- Equipment replacement and retrofit in occupied buildings
- Electrical connections under our own C-10 classification
- Building-automation and controls integration
- Title 24 compliance forms, acceptance testing coordination and permitting
- Startup, commissioning and documented closeout

Process
How a commercial installation runs
The same sequence whether it's one unit or a full building: the difference is how many people we coordinate with.
- 01
Scope & submittals
Plans or site walk
We review plans or walk the space, confirm loads and equipment selections, and issue submittals and cut sheets for approval.
- 02
Design coordination
Before fabrication
Duct routing, curb and structural coordination, electrical requirements and controls scope are settled with the GC, engineer and other trades before anything is fabricated.
- 03
Installation
Sequenced with trades
Rough-in, equipment set (crane day planned in advance), duct, piping, electrical and controls, sequenced with your schedule.
- 04
Startup & commissioning
Documented
Refrigerant charge verified, airflow balanced, controls sequenced and tested, and a startup report produced for the closeout package.
- 05
Closeout
Documented
When the project needs one, the mechanical inspection is scheduled and attended; Title 24 acceptance documentation is completed and O&M information handed over.
What affects price
What drives a commercial installation quote
We quote from plans or a site walk, itemized by scope. No two projects price the same, but these are the variables that matter most.
- Equipment type and tonnage
- A rooftop package unit, a split system and a VRF system at the same capacity are very different costs; capacity and efficiency tier move the number further.
- New install vs. replacement
- Replacement reuses curbs, duct and electrical where they're sound; new construction and TIs add duct fabrication, structural and electrical scope.
- Roof access and crane
- Crane size, street closure or permit requirements, and whether a curb adapter is needed all affect the equipment-set day.
- Ductwork and controls
- New or reworked duct, dampers, zoning and building-automation integration are priced as their own scope.
- Title 24 and permitting
- Acceptance tests, third-party verification where required, and jurisdiction permit fees vary by project and city.
- Schedule and occupancy
- Work in an occupied building (after-hours, phased or with temporary cooling) costs more than an open shell.
