Commercial rooftop HVAC repair in Port St. Lucie

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

What Port St. Lucie homeowners ask us

That depends on what failed and on the equipment. We tell you the number after we look at the unit, and if replacing it is on the table, you get both numbers.
No. Everyone here is paid hourly, not on commission. When a repair will hold, that's the recommendation.
Yes. We answer 24/7. Sundays and holidays are billed at double time.
