A heat pump running in heating mode works its reversing valve and compressor hard, and in Beaverhead County there is no idle season to soften that load. Homes in Beaverhead County, MT run heat in every month of the year. The compressor cycles through cold-weather demand all year, which is the condition that wears valve seals, degrades refrigerant charge, and stresses the defrost board. A contractor diagnosing a repair here checks those components first, because the accumulated cycling hours tell on them before the auxiliary heat strip or the air handler does.
Ductwork and wiring aside, the repair question in an older house is almost always about what a contractor finds inside the unit itself. Half the homes in Beaverhead County, Montana were built in 1979 or earlier (2020-2024 ACS 5-year). That spread of building ages means a contractor opening a heat pump in this county may find components tied to refrigerant lines, compressor designs, and control boards that have passed through multiple compatibility breaks since the house was built. A part that scans as a standard replacement in a catalog can arrive and fit nothing inside the cabinet. What the opened system physically contains, and whether the supply chain still stocks for it, is what sets the repair cost and timeline here.
The Parts of a Heat Pump a Contractor Checks During Repair
The outdoor unit is the piece most homeowners recognize first, sitting on a pad beside the house. Inside it are the compressor and the condenser coil, and when a repair call comes in, these are often where a contractor looks first. A failed compressor or a damaged coil will stop the system from moving heat in either direction.
Inside the house, the air handler holds the evaporator coil and the blower fan, pulling air across the coil and pushing it through the home. The refrigerant lines connect the two units, and the reversing valve inside the outdoor cabinet is what lets the system shift between heating and cooling. A fault in any of these can show up as weak airflow, wrong temperatures, or a unit that runs but does nothing.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which parts and conditions apply to your specific home.

Licensing Rules for Contractors in Beaverhead 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.
