Rooftop units
Service, repair, and replacement for packaged RTUs — gas-electric, heat pump, and dedicated outside air units.
Service
Commercial HVAC
Comprehensive heating, ventilation, and air conditioning service for commercial and industrial facilities — from emergency repair on a rooftop unit at 2 a.m. to a full chiller plant overhaul.

Every system in the mechanical room.
Our techs work on the full breadth of commercial HVAC equipment — packaged units, split systems, central plants, and the controls that tie them together.
Chillers & cooling towers
Air-cooled, water-cooled, and absorption chillers — start-up, teardown, eddy-current tube testing, refrigerant management.
Boilers & hot water
Hot water and steam boilers, condensate systems, combustion analysis and tuning, and code-required annual inspections.

VRF / VRV systems
Multi-zone variable refrigerant systems — leak detection, EEPROM diagnostics, indoor-unit replacement, condenser service.

Why Starnes
We service what we install — and we install what we service.
Most HVAC firms split into install crews and service crews that don't talk. Ours don't. The tech who shows up to fix your rooftop unit at 2 a.m. has probably worked on the install crew that put it there.
That means faster diagnosis, cleaner repairs, and a service record that actually reflects what's in your building.
- Factory-trained on Trane, Carrier, Daikin, JCI, Lennox, Mitsubishi, and LG
- EPA-certified universal techs on every truck
- Manufacturer warranty handling — we file the paperwork, you don't
- Aligned with your in-house facilities team, not in competition with them
- Same crew for service and projects — no handoff friction
