A contractor diagnosing a heat pump repair in Georgetown County starts with the refrigerant circuit and the reversing valve, because the heating season is where a heat pump works hardest. Homes in Georgetown County, SC run heat about five months a year, from November through March. Through those months, the system runs in its less efficient direction, extracting heat from cold outdoor air, which puts steady demand on the compressor and reversing valve in ways summer cooling does not. Wear shows up there first. A repair quote that skips the reversing valve and focuses only on electrical components is leaving out the part the season actually stresses.
Ductwork in a house this old tells a contractor something useful before the heat pump itself is ever opened. Half the homes in Georgetown County, South Carolina were built in 1993 or earlier (2020-2024 ACS 5-year). Duct runs from that period were fabricated and sealed with materials and methods that do not hold up the same way under coastal South Carolina humidity, and by the time a heat pump shows a fault, the duct system has often contributed to it. A contractor doing repair work here checks static pressure, inspects accessible joints, and looks for liner breakdown, because a refrigerant charge or a failing capacitor can be the visible problem while degraded ductwork is the reason the system has been working harder than it should.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad beside the house and holds the compressor, the outdoor coil, and the fan. The compressor is the piece contractors look at early when a heat pump stops doing its job. A failed compressor, a dirty or bent coil, or a fan that has stopped moving air can each bring the whole system down.
Inside the house, the air handler hangs in a closet, attic, or mechanical room and moves conditioned air across an indoor coil. The refrigerant lines running between the two units and the reversing valve, which tells the system which direction to run, are the other pieces a contractor traces when the outdoor unit seems fine but the air handler is not performing.
The drawing shows a typical layout, and a licensed contractor determines which parts apply and what condition they are in for your specific home.

Severe Weather Events in Georgetown County
Georgetown County's climate puts real stress on heat pump systems, which run year-round against both heat and cold. Weather-driven strain shortens equipment life and pushes repair needs up, which is why local conditions shape the repair picture as much as the equipment itself.
