A heat pump in Covington County runs its hardest work in heating mode, and the compressor and reversing valve carry most of that load. Homes in Covington County, MS run heat about five months a year, from November through March. By the time a homeowner calls for repair, those components have been cycling through cold nights for months, and a contractor checking one failed part has reason to look at what ran alongside it. Refrigerant charge, contactor condition, and reversing valve response all degrade under sustained heating demand, and a repair scoped too narrowly often comes back.
Ductwork in housing this old carries a record of everything that has moved through it: settled debris, degraded seals, sections that have shifted at their joints. Half the homes in Covington County, Mississippi were built in 1989 or earlier (2020-2024 ACS 5-year). A contractor opening a heat pump here will check the refrigerant circuit and the electrical connections, but what determines whether the repair holds is often the condition of the duct runs feeding it. Leaks or blockages there put stress back on the unit, and a repair made without addressing them tends to come back.
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 outdoor coil. These are the pieces that take the most strain, so a contractor starts here. A failed compressor means no heat movement at all; a damaged or iced-over coil means the system runs but cannot do its job.
Inside, the air handler hangs in a closet, attic, or mechanical room and pushes conditioned air through the house. The reversing valve lives in the outdoor unit and is what lets a heat pump heat in winter and cool in summer. The refrigerant line set connects the two units, and a fault anywhere along it affects both sides.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific house and system.
