A ductless mini-split in Manchester is a room-by-room decision. Amoskeag mill blocks and wood-frame triple-deckers still heat with steam or hot water. North and west of the river, post-war ranches and split-levels are more often forced air. One head in the living room does not heat a closed bedroom down the hall. Mill buildings and tight lot lines make outdoor units hard to reach and easy to bury in snow if they sit at grade. Line-set routes, a condensate pump, and a place for the outdoor unit are the parts that change the quote. Liberty Utilities delivers natural gas on some Manchester streets and not others. Oil and propane remain where there is no main. Electric service is usually Eversource. Confirm both on a bill. If the rest of the house stays on oil, propane, or a boiler, say that. Permits are Manchester's, not the state's. Ask who files with the city's building inspection office before a replacement. Confirm license and insurance. The installer quotes after seeing the rooms.
