On a heat pump repair call in Gilliam County, a contractor looks at the compressor and reversing valve before anything else, because the heating season is where the machine earns its wear. Homes in Gilliam County, OR run heat about eight months a year, from October through May. Capacity drops as outdoor temperatures fall, which means the compressor works harder in the coldest weeks than it does in summer, cycling more often and running longer each cycle. Refrigerant lines, the defrost board, and the reversing valve all carry that load. A contractor quoting a repair here establishes how much of that history the system has absorbed before settling on parts.

Ducts in a house this old carry a record of every system that ran through them. Half the homes in Gilliam County, Oregon were built in 1961 or earlier (2020-2024 ACS 5-year). A contractor opening a heat pump here checks whether the ductwork is still sealed well enough to move conditioned air efficiently, because gaps and deteriorated joints that accumulated over decades show up as performance problems that look, from the outside, like a failing unit. If the duct runs have been modified since the original build, a section may be undersized for where the heat pump sits in the system now. Sorting that out before replacing any parts keeps the repair bill from growing after the fact.
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. The compressor is where a contractor starts when a heat pump stops doing its job. A failed compressor, a refrigerant leak at the coil, or a seized fan motor in that cabinet will each show up differently, and reading those signs is the first order of business.
The air handler lives inside the house, most often in a utility closet or an attic, and it contains the indoor coil and the blower that moves air through the home. The expansion valve and refrigerant lines connecting the two units are also common trouble spots. A reversing valve inside the system, which directs heat in or out depending on the season, gets checked when the unit runs but heats or cools in only one direction.
