A contractor quoting a heat pump installation in Montgomery County is not sizing against a punishing climate. 63 severe weather events were recorded in Montgomery County, Indiana between 2015 and 2024. At that rate, severe weather is an occasional event for most households, not a standing condition that drives every spec decision. What shapes the install is the house itself: duct layout, existing infrastructure, and how the previous system was put in. A contractor who gets those details right is doing the work that actually determines whether the new unit runs well.
Ductwork laid for an older heating system carries assumptions about airflow, static pressure, and return-air sizing that a heat pump does not share. Half the homes in Montgomery County, Indiana were built in 1967 or earlier (2020-2024 ACS 5-year). That means a contractor sizing a heat pump here is checking whether the existing duct system can actually deliver what the new unit produces, not just whether the unit fits the space. Electrical service gets the same look: the panel and the wiring it feeds were put in for something with different draw requirements. What a contractor finds in those two places sets the scope of the job before the equipment is even selected.
What a Heat Pump Installation Covers, Piece by Piece
The outdoor unit is the piece most homeowners notice first. It sits on a pad beside the house and holds the compressor and the main coil. Inside, the air handler mounts in a utility space, a closet, or an attic and pushes conditioned air through the home. Together these two cabinets are the core of what a contractor brings in and sets into place.
A refrigerant line set runs between the two units, carrying the working fluid back and forth through insulated copper tubing. A thermostat goes on an interior wall and gives the homeowner control over the whole system. Some installations also include a supplemental electric heat strip inside the air handler, which a contractor sizes and positions based on what the house requires.
The drawing shows a representative layout of these components, and a licensed contractor determines exactly how each one fits the conditions in your house.

How hard a heat pump works is shaped by what the weather here actually does, not what it does somewhere else. The right equipment choice and installation spec for Montgomery County starts with understanding the local load.
