Takes about a minute. No obligation.
A contractor quoting a heat pump repair here has to reckon with what the system has already been through. Homes in Cherokee County, SC run heat about seven months a year, from October through April. The outdoor coil runs in heating mode through cold snaps, rains, and freeze-thaw cycles that force the defrost cycle to trigger repeatedly, and the reversing valve shifts direction every time the unit switches between heating and cooling. Those components carry the load, and by the time a heat pump shows a symptom worth calling about, a contractor checking only the obvious fault often finds secondary wear behind it that changes the scope of the repair.
Refrigerant lines corrode, capacitors weaken, and contactors pit in ways that accumulate quietly until the system stops. Half the homes in Cherokee County, South Carolina were built in 1984 or earlier (2020-2024 ACS 5-year). A contractor who opens a heat pump in a house from that part of the housing distribution is often finding components that have cycled through many heating and cooling seasons, and whether a given part is still in production matters as much as whether it has failed. Some parts for equipment of that vintage are available; others require substitutes that a contractor has to spec carefully before ordering.
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 what contractors look at early: when it fails, the system runs but moves no heat. The condenser coil surrounds it, and a damaged or fouled coil shows up as poor performance in either heating or cooling mode.
Inside the house, the air handler contains the blower motor and the evaporator coil, usually in a closet, attic, or utility room. The reversing valve, which sits inside the outdoor unit, is the part that lets a heat pump heat as well as cool, and a stuck or failed valve is why a system might work in one mode but not the other. The expansion valve and refrigerant lines connect the two units and are checked when pressure or flow readings are off.
The drawing shows a typical layout, and a licensed contractor will determine which components apply to your specific system and home.
