A contractor diagnosing a heat pump repair in this area starts by checking the components that carry the hardest load during severe weather: the capacitor, contactor, and refrigerant lines. 84 severe weather events were recorded in Washington County, Tennessee between 2015 and 2024. At that rate, severe weather is a standing condition of operating a heat pump here, and the parts that absorb it most show wear in predictable ways. A contractor who skips that check and quotes a compressor replacement may be pricing the wrong fix.
Older ductwork and wiring get the attention, but on a repair call what actually decides the job is what a contractor finds once the heat pump is open. Half the homes in Washington County, Tennessee were built in 1985 or earlier (2020-2024 ACS 5-year). Equipment installed into houses of that era has cycled through at least one major overhaul in parts availability and refrigerant standards since. A contractor opening a failed compressor or reversing valve here has to confirm whether the replacement parts that unit accepts are still manufactured before the repair scope can be set.
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 one of the coils. The compressor is where most repair calls lead: it pressurizes the refrigerant that carries heat between inside and outside. When the outdoor coil or its fan motor is the problem, the unit runs but cannot move heat effectively.
Inside, the air handler hangs in a closet, attic, or utility room and holds the second coil, a blower, and the metering device that controls refrigerant flow. The refrigerant lines connecting the two units and the reversing valve, which tells the system which direction to run, are also points a contractor examines when the system heats in one mode but not the other.
The drawing shows a typical layout, and a licensed contractor determines which components apply and what condition they are in for your specific home.
