A heat pump in Wasco County earns its keep hard. Homes in Wasco County, OR run heat about ten months a year, from September through June. The compressor cycles through both heating and cooling demand across that span, and the reversing valve, the component that switches the system between modes, toggles with it. A contractor diagnosing a failed heat pump here checks that valve early, because the wear pattern it shows after years of near-continuous use tends to explain faults that a refrigerant test alone will not.
Half the homes in Wasco County, Oregon were built in 1973 or earlier (2020-2024 ACS 5-year). That gap between when these houses were built and what runs in them today shows up once a contractor opens the unit. Corroded electrical connections, refrigerant lines that have cycled through many seasons, and contactors worn past their rated life are common findings in stock of this vintage. Whether the parts a heat pump of this generation takes are still manufactured is a real question on many Wasco County jobs, and the answer shapes the repair scope before labor or anything else 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, which is where most repair calls start. The compressor moves refrigerant through the system, and when it struggles or fails, the whole system follows. The coil wrapped around that outdoor cabinet transfers heat to or from the air outside, and a bent, iced, or dirty coil will push the compressor toward failure.
The air handler lives inside, usually in a utility closet, attic, or basement, and it contains the indoor coil and the blower that moves conditioned air through the house. The reversing valve sits inside the outdoor unit and is what lets a heat pump run in both directions. A contractor checks the refrigerant lines connecting the two units for leaks, and inspects the expansion valve that controls refrigerant flow between the coils.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines what applies to your specific home and equipment.

Severe Weather Events in Wasco County
Weather puts real load on heat pump systems. The harder the climate pushes, the harder the equipment works, and that accumulated stress is what repair needs grow from.
