A heat pump repair quote in Richland County starts with how the system has been running, and heating mode is where it runs hardest. Homes in Richland County, SC run heat about five months a year, from November through March. Capacity drops as outdoor temperatures fall, so the compressor and reversing valve cycle more aggressively in February than they do in October. A contractor checking a refrigerant fault or an intermittent heating loss looks at the reversing valve first, then the coil connections, because those are the components that carry the load when the unit is working against cold air. Coil corrosion and valve wear show up in the repair history before they show up in the thermostat reading.
Ductwork in a house this old was sized and routed for whatever ran in it originally, and the heat pump sitting there now may be two or three generations removed from that original install. Half the homes in Richland County, South Carolina were built in 1989 or earlier (2020-2024 ACS 5-year). When a contractor opens a heat pump in stock like this, the question that shapes the repair bill is whether the parts the system takes are still being made, and a unit that predates a refrigerant changeover can push that answer into special-order or unavailable territory. That is what sets the scope and the cost.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is where most repair calls begin. It sits outside the house and holds the compressor, which moves refrigerant through the system, and the condenser coil, which releases or absorbs heat depending on the season. When either fails, the whole system stops doing its job.
Inside the house, the air handler pushes conditioned air through the home. It contains the evaporator coil, which works in tandem with the outdoor unit, and the blower motor, which drives airflow. The reversing valve, also inside the refrigerant loop, is what lets the system run in both heating and cooling directions, and it is a common point of failure when a heat pump heats in one season but not the other.
The drawing shows a typical heat pump layout, and a licensed contractor determines which parts apply to your specific system and what each one needs.
