For a heat pump install in Montgomery County, the heating side drives every sizing decision a contractor makes. Homes in Montgomery County, NY run heat about eight months a year, from October through May. As outdoor temperatures drop, a heat pump's capacity falls, and a unit that looks adequate on paper in October strains to keep up in January. A contractor has to establish how cold the site actually gets at the design low before they can specify the right system or decide whether a backup heat source is needed. Undersizing shows up as comfort complaints and short cycling, not as a number on a spec sheet.
Ductwork laid out for a furnace or a window-unit era carries different dimensions, different trunk sizes, and different return configurations than a heat pump wants. Half the homes in Montgomery County, New York were built in 1944 or earlier (2020-2024 ACS 5-year). That gap between what was built into the house and what a new heat pump needs is where the installation question actually lives. A contractor has to trace the existing runs, check whether the returns are adequate, and assess the electrical service before the equipment itself is even priced. What the house already has determines the scope.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners notice first. It sits on a pad outside the house and holds the compressor and the main coil, which together do the work of moving heat between inside and out. Inside, the air handler mounts in a utility space, closet, or attic and pushes conditioned air through the home.
A refrigerant line set runs between the two units, connecting them through a small penetration in the wall. The thermostat goes on an interior wall and gives the homeowner control over the whole system. A disconnect box mounts near the outdoor unit and provides a local shutoff point for the equipment.
The drawing shows a typical layout, and a licensed contractor determines what fits and where in your specific home.
