A heat pump in Bingham County runs its compressor hard in both directions, pulling heat in through winter and pushing it out through the shoulder months either side. Homes in Bingham County, ID run heat about ten months a year, from September through June. That means the reversing valve cycles repeatedly across a long shared season, and a contractor diagnosing a fault has to distinguish normal wear on those cycles from a component that failed ahead of schedule. The compressor itself carries the bulk of that load. A quote that ignores how long this system has been working is a quote built on incomplete information.
Ductwork routed for a different era of heating, service wiring updated in stages, heat pumps dropped into houses that were never designed around them: these are the conditions a contractor opens up to. Half the homes in Bingham County, Idaho were built in 1978 or earlier (2020-2024 ACS 5-year). That history shows up inside the equipment. Refrigerant lines that have cycled through decades of temperature swings, electrical connections that have carried uneven loads, compressor internals worn against demands the original install never anticipated. Whether a part is still manufactured for a system running in stock like this is a real question, and the answer changes the repair scope before any other variable does.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad beside the house and holds the compressor and the condenser coil. These are the pieces a contractor goes to first when a heat pump stops heating or cooling properly. A failed compressor, a dirty or damaged coil, or a refrigerant problem all show up here.
Inside, the air handler hangs in a closet, attic, or utility room and moves conditioned air through the house. The expansion valve and the reversing valve both live within the refrigerant circuit and are common sources of trouble when the system runs but does not perform. The thermostat, mounted on a wall, controls everything and is often the first thing a contractor tests.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific home and system.
