A ductless mini-split in Derry is a room-by-room decision. A village center and older roads sit next to many late-twentieth-century subdivision houses. Rooms over garages overheat and underheat. Furnaces and water heaters often share a garage alcove or a basement finished after the equipment went in. One head in the living room does not heat a closed bedroom down the hall. Condensers sit close to decks and property lines. Access is the hidden part of the quote. Line-set routes, a condensate pump, and a place for the outdoor unit are the parts that change the quote. Natural gas is not the default. Liberty marks Derry as a very small service area. Most heating proposals should start from oil, propane, or a heat pump. Electric service is often Eversource.

Ask who files and whether an inspection is required for the equipment you are changing. Confirm license and insurance. The installer quotes after seeing the rooms.
