A contractor diagnosing a heat pump here looks at the compressor and reversing valve before anything else. Homes in Jackson County, OR run heat about nine months a year, from October through June. Across a season that long, those two components cycle through heating mode far more than the coil or refrigerant circuit, and the wear pattern reflects it. Refrigerant loss is often blamed first on a struggling system, but in most failed heat pumps here the compressor has already been laboring through repeated cold-weather capacity drops. A contractor who pulls the electrical history and checks the compressor amp draw under load will find the answer faster than one who goes straight to the refrigerant.
Refrigerant lines, contactors, reversing valves, capacitors: what a heat pump in this county turns out to need once it is opened depends on what that specific unit has been asked to do in that specific house. Half the homes in Jackson County, Oregon were built in 1985 or earlier (2020-2024 ACS 5-year). Stock built for earlier equipment has been adapted and re-adapted since, and the repair scope follows what accumulated inside the system, not what the address looks like from the street. Parts for some of the units still running in houses like these are no longer in general distribution, which changes what a contractor quotes and how long a job takes.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize, sitting on a pad beside the house. Inside its cabinet are the compressor and the outdoor coil. The compressor is where most repair calls begin, since it is the part that does the hardest mechanical work. The coil sits around it and is where the outdoor air does its job.
Inside the house, the air handler holds the indoor coil and the blower fan that moves conditioned air through the home. The reversing valve, which lives in the outdoor unit, is the part a contractor checks when the system heats in one direction but not the other. The expansion valve and the refrigerant lines that run between the two units round out what a contractor traces when the system is not performing.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific home and equipment.
