A heat pump doing repair work in Lee County has a specific history behind it. Homes in Lee County, MS run heat about five months a year, from November through March. The compressor cycles through heating mode across those cold months, and defrost demand runs with it every time outdoor coils ice up. What a contractor finds when they pull the unit apart reflects that load: worn reversing valves, stressed defrost boards, and refrigerant circuits that have been working through the cold rather than sitting dormant. A repair quote here starts with the heating side.
Half the homes in Lee County, Mississippi were built in 1988 or earlier (2020-2024 ACS 5-year). A heat pump running in a house that old sits on top of whatever wiring and refrigerant lines the original installation left behind, and those are what a contractor finds when the system comes apart. Parts a unit that age takes are sometimes still in production and sometimes sourced from shrinking supply. What the opened system turns out to contain decides the repair scope and the parts list, and the house itself is as much of the job as the unit.
The Parts of a Heat Pump a Contractor Checks During Repair
The outdoor unit is the piece most homeowners recognize first, sitting on a pad beside the house. Inside it are the compressor and the condenser coil, both of which a contractor goes to early in a repair call, because faults there tend to stop the system outright. The air handler lives inside, usually in a closet, basement, or attic, and pushes conditioned air through the home.
The refrigerant lines run between the two units and carry the working fluid the system depends on. A leak or a blockage in those lines shows up as a system that runs but fails to move enough heat. The reversing valve, which sits inside the outdoor unit, is what lets a heat pump heat in winter and cool in summer, and it is a common focus when a system works in one mode but not the other.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines exactly which parts need attention in your home.
