Commercial rooftop HVAC repair, done on the roof
The rooftop unit sits in sun, rain, and salt air all year. Eventually something gives. Commercial rooftop HVAC repair usually means one motor, one compressor, or one control, and we find which.
We diagnose it up there, fix what will last, and plan the changeout only when the cabinet is done.
Motors, compressors, controls, and coils
Those four cause most rooftop failures. A 20-ton Trane from 2001 came back to life in early 2024 with a new fan motor. Old doesn't always mean finished.
A rusted-out cabinet is a different job
At that point it's a replacement, with a crane and a permit. We give you both numbers and plan around your hours.
What the visit covers
- Rooftop unit diagnostics
- Compressor, condenser, and blower repair
- Control and electrical troubleshooting
- Coil cleaning
- Changeouts with crane and permit coordination

York system at a local business, Port St. Lucie
A commercial York system and a wall-mounted mini split at the same business. We serviced the outdoor condensers and the cooling equipment so the place stays cold through August.

Rooftop package unit repair, Stuart
Rooftop package unit on a commercial building. We made the repair up top and tested it under load before we came down. A business can't wait a week for cold air.

Line set insulation above a ceiling, Fort Pierce
Commercial space. The insulation on the refrigerant lines above the ceiling had broken down and was sweating. We replaced it. Bare lines drip, and drips turn into stained ceiling tiles.

VRF system installed at a school, Port St. Lucie
A VRF cooling system for a school. It came up fast and cooled the rooms the way the building needed, so the students weren't sitting in the heat.
What happens when you call
Tell us the building and what the unit is doing. JD usually picks up. If he's under a house or on a roof, someone calls you back. Ask about the diagnostic fee and we'll tell you before anyone drives out.
