ACCREDITEDA rooftop package unit puts the whole system in one cabinet on the roof of a commercial building: cooling, heat, blower, filters, and the dampers that mix outside air with return air. It serves a retail box, an office floor, or a restaurant, typically in the three- to twenty-five-ton range, with its ductwork dropping straight through the roof beneath it. A homeowner with a pitched roof is on the wrong page; the residential systems are listed alongside.
Replacing one is a job about the roof as much as the machine. The unit sits on a curb, and a new unit's footprint rarely matches the old curb exactly, so either an adapter curb bridges the difference or a model built as an exact-fit replacement is chosen to avoid it. Either way the existing duct connections and the roof membrane are what get preserved, and the lift itself is a crane job planned around the building's parking and access. Single-zone versus multi-zone, and whether the economizer actually opens to outside air when it should, are settled before the crane is booked.

Ducts, walls and a condo board decide this more often than the brand does. How the choice actually gets made on an estimate visit in Greater Boston, and why sizing matters more than the system type.
Three real options in 2026 and only one of them carries state money. What each costs you beyond the equipment, the middle path nobody offers, and why the envelope math comes before the equipment math.
Two quotes on the same house can differ by thousands without either one padding the number. What actually moves it: where the condenser can go, the electrical panel, the duct condition, and the sizing nobody ran.
