Common Questions
Commercial HVAC Installation FAQs
Can you install RTUs on an existing building?
Yes — we regularly retrofit rooftop units onto existing commercial buildings. We assess structural capacity, curb compatibility, and ductwork routing before quoting. Crane placement is included in our scope.
How long does a commercial HVAC installation take?
Timeline depends on the scope: a single RTU replacement is typically 1–2 days. A multi-zone new construction project may take 2–6 weeks depending on building size and coordination with other trades.
