A heat pump in Spartanburg County earns its wear on both sides of the refrigerant cycle, not just one. Homes in Spartanburg County, SC run heat about seven months a year, from October through April. The reversing valve, the compressor, and the outdoor coil all work through the heating half of the year, then shift straight into cooling without a long rest period in between. A contractor diagnosing a refrigerant or electrical fault here checks how many cycles those components have absorbed across both modes, because the failure pattern on a year-round machine differs from one that sits off through a long summer or a long winter.
Ductwork designed around older equipment carries different static pressure, different leakage rates, and different airflow assumptions than what heat pumps now require. When a failed unit gets opened, a contractor may trace the fault to the refrigerant circuit or the reversing valve, only to find that what pushed the system past its limits was the duct runs feeding it. Half the homes in Spartanburg County, South Carolina were built in 1990 or earlier (2020-2024 ACS 5-year). That concentration of older stock means contractors here regularly work on heat pumps that have been compensating for undersized or leaking ductwork for years, and the wear pattern inside the unit reflects it.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize on sight. It sits outside the house and holds the compressor, which moves refrigerant through the system, and the coil and fan that release or draw in heat. When a heat pump stops doing its job, the compressor and that outdoor coil are where a contractor looks first.
Inside the house, the air handler contains a second coil and a blower that pushes conditioned air through the home. The refrigerant lines running between the two units and the reversing valve, which switches the system between heating and cooling, are also common sources of faults a contractor will trace.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific system and home.
