A heat pump working a long heating season puts its hardest load on the reversing valve and the refrigerant circuit, both of which cycle every time the system switches between modes. Homes in Scott County, AR run heat about seven months a year, from October through April. By late winter, a valve that was marginal in the fall has been switching under load for months, and that is where a contractor starts. Coil condition follows, because capacity loss in cold weather often shows up there first.
Ductwork in houses this old was sized and routed for whatever system ran in them first, and that system has since been replaced at least once. Half the homes in Scott County, Arkansas were built in 1981 or earlier (2020-2024 ACS 5-year). A heat pump repair here opens a unit whose internal components may have outlasted the supply chain behind them. When a contractor pulls the panels, the question is whether what failed can still be sourced, or whether the repair scope has to widen to account for discontinued parts.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is usually the first thing a homeowner notices, and it is where a contractor starts. It holds the compressor, which moves refrigerant through the system, and the outdoor coil, which transfers heat. When either of those is the problem, the whole system feels it.
Inside the house, the air handler contains the indoor coil and the blower that moves conditioned air through the home. The refrigerant lines connecting the two units and the reversing valve, which is what lets a heat pump both heat and cool, also draw attention during a repair call.
The drawing shows a general layout of these components, and a licensed contractor determines exactly what applies to your home and system.
