Sizing a heat pump for Pondera County means solving a harder problem than sizing one for a mild climate, because a heat pump's heating capacity drops as outdoor temperatures fall, and the coldest weeks here are exactly when the system is asked to deliver the most. Homes in Pondera County, MT run heat about ten months a year, from September through June. A unit that is slightly undersized will run longer and harder trying to close that gap, putting load on the compressor and the reversing valve through the months that already ask the most of them. A contractor quoting an install here has to run a proper load calculation and confirm what back-up resistance heat, if any, the system will need to avoid shortfalls on the coldest nights.
Ductwork and electrical panels in older houses were built around whatever was running at the time, and a heat pump puts different demands on both than what those houses were originally wired for. Half the homes in Pondera County, Montana were built in 1968 or earlier (2020-2024 ACS 5-year). That spread across the housing stock means a contractor quoting a heat pump installation here prices the panel assessment and any service upgrade before settling on the unit itself, because the panel's capacity sets the ceiling on what the new equipment can be.
What a Heat Pump Installation Puts in Your Home
The outdoor unit is the piece most homeowners see first. It sits on a pad beside the house and holds the compressor and the outdoor coil, which together do the core work of moving heat between inside and outside. 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, carrying the fluid that links the outdoor and indoor sides of the system. A thermostat goes on an interior wall where it reads the home's temperature and tells the system when to run.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the specific house.

Licensing Rules for Pondera County, Montana
Montana’s contractor licence does not reach a casual, minor or inconsequential job whose total price for labour, materials and everything else is less than $2,500 — and the exemption is lost if the work is only part of a larger operation, or if a job is divided up to get under the figure.
Montana requires a current construction contractor licence from the Department of Labor and Industry: an individual or business may not engage in business as a construction contractor without one.
