Commercial HVAC Installation

The old unit may have been oversized at install, the building use may have changed (fewer or more occupants, added computers, altered partitions), and current efficiency equipment often does more per nominal ton than older units. A load calculation sizes the replacement to the actual building, not an assumption that twenty-year-old sizing is still right.

A rooftop changeout typically needs: crane time scheduled, a curb adapter if footprints differ, updated electrical disconnect if required, a new condensate route if required, Title 24 compliance paperwork, and a permit from the local building department. We coordinate all of it in the scope rather than handing pieces to the owner.

A straight package-unit changeout on a single zone can often be done in a working day plus crane time. More involved projects — multi-unit buildings, changes in equipment type, duct modifications — are quoted with a schedule as part of the scope. We don't quote by phone; a commercial scope needs an on-site evaluation.

Yes — on retail and office properties, we commonly schedule work for off-hours or weekends so the business doesn't lose operating days. Phased replacements across multiple units on the same building are coordinated so the space never loses conditioning entirely.
