Rooftop unit change-outs
Crane day to commissioning — including curb adaptation, refrigerant piping, electrical, controls integration, and start-up. We coordinate the crane, the roof inspector, and the AHJ.
Service
Project Support
Design-build, retrofit, and equipment-upgrade projects delivered by tradespeople who know the install — and the service that comes after. From a single rooftop unit replacement to a campus-wide chiller plant.
What we deliver
Projects, sized to your scope.
We don't chase mega-projects we can't staff or one-day jobs that lose money. Our sweet spot is the work that's too complex for a handyman and too operational for a generalist GC.
Chiller plant retrofits
End-of-life chiller replacement, capacity upgrades, condenser water system redesigns, VFD additions, primary-secondary conversions.
Boiler & hot water upgrades
Atmospheric-to-condensing conversions, boiler plant redundancy upgrades, low-NOx swaps for permit compliance.
Controls upgrades
Pneumatic-to-DDC conversions, Niagara migrations, head-end replacements — coordinated with the mechanical work so the system actually runs when we're done.
Tenant fit-outs
HVAC, controls, plumbing for tenant build-outs — sized to your space plan, sequenced around your construction schedule, commissioned to your standards.
Energy retrofits
ESCO-eligible upgrades — variable speed drives, economizer additions, heat recovery, controls optimization. Measurement & verification built in.
Why Starnes for projects
The crew that designs it, installs it, and keeps it running.
Most mechanical projects suffer the same handoff problem: design firm hands drawings to install crew, install crew hands a system to a service company, service company spends two years untangling assumptions nobody documented. We close that loop.
Our design-assist team sits with our install foremen and our service techs. The job that hits the field has been pressure-tested by the people who'll service it. The system you operate matches the drawings — because we made both.
- Design-build and design-assist delivery
- Single point of accountability — design through warranty
- Coordinated with our own service team — no handoff gap
- Manufacturer relationships expedite long-lead equipment
- Permits, inspections, and AHJ coordination handled
- M&V baked in — you can prove the savings
Have a project in mind?
Let's scope it together.
Send us your scope (or just the symptoms — "the chiller is at end-of-life and we're not sure what to do next" is a great starting point). We'll walk the site, develop options, and come back with a proposal.
