A contractor diagnosing a heat pump repair in Tate County starts with the refrigerant side and the reversing valve, because those are what the heating season loads hardest. Homes in Tate County, MS run heat about five months a year, from November through March. Cold outdoor air pulls down the heat pump's capacity as temperatures drop, so the system cycles more often and the compressor works harder to hold setpoint. A component that was already weakening rarely survives to spring. By the time a homeowner calls, the reversing valve or the refrigerant circuit usually shows exactly where the season's load concentrated.
Ductwork and refrigerant lines in houses this old have served whatever equipment was swapped in over the decades, and the parts a heat pump draws on reflect that history. Half the homes in Tate County, Mississippi were built in 1992 or earlier (2020-2024 ACS 5-year). When a contractor opens a unit here, what matters is whether the capacitors, contactors, and coil connections inside it are still in production and can be sourced, or whether the system has reached the point where parts are no longer made for it. That answer comes from what the opened unit shows, not from the year on the permit.
The Parts of a Heat Pump a Contractor Checks During Repair
The outdoor unit is the piece most homeowners can point to right away. It holds the compressor and the outdoor coil, and when either one fails the system stops moving heat altogether. The air handler sits inside, usually in a utility closet or attic, and its coil and blower are where a contractor looks when the indoor side of the problem shows up.
The refrigerant lines run between the two units and carry the working fluid that makes the whole exchange possible. A leak anywhere along those lines, or at the fittings where they connect, will pull the system down even when the compressor and coils are otherwise sound. The reversing valve sits inside the outdoor unit and is what lets a heat pump heat in winter and cool in summer.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific system and house.
