A heat pump here carries a meaningful heating load across a stretch of calendar that accumulates real stress on the reversing valve, the refrigerant circuit, and the outdoor coil. Homes in Abbeville County, SC run heat about five months a year, from November through March. Cold air thins a heat pump's capacity before the thermostat knows it, so a system that was slightly undersized at install shows its limit first on the hardest January nights. A contractor diagnosing a repair in this county checks refrigerant charge and reversing valve function early, because those are the components that cycle hardest through a long heating season and give out before anything else does.
Ductwork installed alongside the original heating systems in Abbeville County's oldest houses was not sized or sealed for the pressure balance a heat pump expects. When a repair call comes in and the system opens up clean, that ductwork is often where the real diagnostic work begins. Half the homes in Abbeville County, South Carolina were built in 1980 or earlier (2020-2024 ACS 5-year). A contractor who finds a heat pump underperforming but mechanically sound will pull airflow readings and check for duct collapse or separation before pricing any refrigerant work, because a sealed and balanced duct run changes what those readings say.
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 set of coils. The compressor is usually where a contractor starts: it pressurizes the refrigerant that makes the whole system run, and when it fails the system stops doing anything useful. The coils wrapped around it are the next stop, since damaged or corroded coil surfaces show up clearly during a visual check.
Inside the house, the air handler holds a second coil and a blower fan that pushes conditioned air through the home. The reversing valve lives in the outdoor unit and is what lets a heat pump move heat in either direction. Refrigerant lines run between the two units, and a contractor will inspect them along with the expansion valve that controls refrigerant flow into the indoor coil.
The drawing shows a typical layout, and a licensed contractor will determine which components apply to your specific system and what work each one needs.
