A heat pump in this area earns its wear on the heating side. Homes in Yamhill County, OR run heat about nine months a year, from October through June. The reversing valve, the coil, and the refrigerant circuit cycle through cold-weather demand month after month, and a small refrigerant leak or a valve that is slow to switch becomes a serious repair by the time a contractor opens the unit. Technicians working a repair here check the refrigerant charge and the reversing valve response early in the diagnosis, because those are the components the heating load has been pressing on the longest.
Ductwork and wiring in a house get changed piecemeal over the decades, and a heat pump that looks standard from the outside can be sitting on connections that were fitted for something different and adjusted since. Half the homes in Yamhill County, Oregon were built in 1990 or earlier (2020-2024 ACS 5-year). When a contractor opens the equipment, the condition of the refrigerant lines, the integrity of the electrical connections, and the state of the contactor and capacitors all carry the record of that history. A part that is failing may be failing because of how it was wired into the system, and the opened unit is where that becomes visible.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and condenser coil. The compressor is where a contractor looks when the system runs but moves no heat, and the coil is what gets checked when the unit ices over or the refrigerant pressure reads off. Both pieces are where most faults show up first.
Inside, the air handler holds the evaporator coil and the blower fan. The coil can develop leaks or freeze solid, and the fan can fail or run weak. The reversing valve, which sits in the outdoor unit, is what a contractor checks when the system heats but will not cool, or the other way around.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific house and equipment.
