A contractor diagnosing a heat pump in Pickens County starts with the compressor and the reversing valve, because those are the parts that carry the weight of a heating season this long. Homes in Pickens County, SC run heat about seven months a year, from October through April. Capacity on a heat pump falls as outdoor temperatures drop, so the compressor works hardest exactly when the season demands the most from it. Wear on the reversing valve shows up the same way: sluggish switching, a system that heats poorly but cools fine, or one that locks into the wrong mode. A contractor who skips those components and goes straight to refrigerant charge is skipping the parts the season has actually loaded.
Ductwork and wiring that have been adapted across more than one equipment generation carry the record of every repair and replacement done before this one. Half the homes in Pickens County, South Carolina were built in 1989 or earlier (2020-2024 ACS 5-year). When a technician opens a heat pump in a house from that era, the refrigerant lines, electrical connections, and drain routing often reflect work done at a previous swap rather than a clean factory install, and a failed capacitor or reversing valve does not stay a simple parts job if the surrounding assembly was already modified. The repair scope a contractor quotes depends on what the opened unit actually shows.
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 condenser coil. These are the first things a contractor looks at, because a failing compressor or a damaged coil is often what stops the system from moving heat at all. When either one misbehaves, the symptoms show up fast.
Inside the house, the air handler holds the evaporator coil and the blower fan. The refrigerant lines run between the two units, and the reversing valve inside the outdoor cabinet is what lets the system switch between heating and cooling. A fault in the valve, a leak in the lines, or a failed blower motor each points a contractor toward a different repair.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific system and home.
