A contractor quoting a heat pump repair in Smyth County has to account for what the equipment has already been asked to carry. 111 severe weather events were recorded in Smyth County, Virginia between 2015 and 2024. At that rate, severe weather is a standing condition for any system in this area, and components that handle heating and cooling transitions, particularly the compressor and reversing valve, accumulate wear against that load over the years. A diagnosis that skips that history risks pricing the wrong repair.
Heat pumps in houses this old have usually outlasted at least one prior system, and the wiring and refrigerant lines that feed them have been touched more than once. Half the homes in Smyth County, Virginia were built in 1973 or earlier (2020-2024 ACS 5-year). That layered history is what a contractor is sorting through when something fails: corroded electrical connections, mismatched line sets, or a refrigerant charge that has drifted across multiple service visits. Whether a part can still be sourced for a unit this vintage is a separate question, and one that shapes the repair bill as much as the diagnosis does.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is usually what a homeowner notices first, sitting on a pad beside the house. It holds the compressor and the outdoor coil, and either one can be the source of a problem when the system stops heating or cooling properly. The compressor is where most repair calls lead.
Inside the house, the air handler moves conditioned air through your home and contains the indoor coil and the blower motor, both of which a contractor examines when airflow is weak or temperatures are uneven. The reversing valve, which sits inside the outdoor unit, controls which direction the system runs, and a failed valve is a direct reason a heat pump blows the wrong temperature air.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components apply to your particular house and situation.
