A contractor quoting a heat pump repair in Horry County starts with the compressor and the reversing valve, not the auxiliary strips. Homes in Horry County, SC run heat about five months a year, from November through March. Capacity drops as outdoor air cools, so the compressor is running at its hardest point in the cycle precisely when the homeowner needs the most from it. That repeated strain shows up in the valve seals and the compressor windings before it shows up anywhere else. A contractor who skips those components and prices a repair around the cheaper parts is pricing the wrong job.
Ductwork laid in a house of this age has already carried several generations of equipment without being replaced, and what a contractor finds when they open a heat pump here reflects coastal heat and humidity far more than the construction date on the permit. Half the homes in Horry County, South Carolina were built in 1999 or earlier (2020-2024 ACS 5-year). That means the refrigerant lines, the coil condition, and what the compressor has accumulated are the variables that shape the repair scope, while the house around them is largely settled. Parts availability for the specific system running today is a sharper question than anything the building tells you.
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 the condenser coil. The compressor is where most repair calls begin. When a heat pump stops moving heat the way it should, the contractor starts there, then moves to the coil, which can restrict airflow if it is damaged or fouled.
Inside, the air handler hangs in a closet, attic, or utility room and contains the blower motor, the evaporator coil, and the reversing valve that tells the system which direction to run. The refrigerant lines connect those two units, and the thermostat on the wall tells the whole system when to act. Any of those pieces can be the source of a fault.
The drawing shows a general layout of how these parts relate to each other, and a licensed contractor determines what applies to your specific system.
