On a heat pump repair call here, a contractor works backward from the compressor and the reversing valve before looking at anything else. Homes in Humphreys County, MS run heat about five months a year, from November through March. Repeated cold-weather cycling stresses both components in ways that summer standby time does not balance out: the compressor starts against low outdoor temperatures, and the reversing valve shifts direction every time the unit switches modes. When either one degrades, the system loses heating capacity before it fails outright, which means a homeowner often calls late. A contractor who quotes a repair without pulling data from both is likely missing where the load has actually landed.
Ductwork laid down for systems that no longer exist, wiring extended or spliced across decades of repairs, refrigerant lines that have cycled through Mississippi summers far longer than their original equipment did: these are what a contractor opens up to when servicing a heat pump in a house typical of this county. Half the homes in Humphreys County, Mississippi were built in 1977 or earlier (2020-2024 ACS 5-year). That history shows up as corroded contacts, weakened line sets, and refrigerant fittings that look sound until pressure tells a different story. The repair scope a contractor quotes after opening the unit is often wider than what brought them to the house in the first place.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and condenser coil. These are where most faults show up. A failed compressor means the system moves no heat at all. A damaged coil or a refrigerant leak at this unit often shows as poor heating or cooling throughout the house.
Inside, the air handler houses the evaporator coil and the blower fan, usually in a closet, attic, or utility room. The expansion valve and refrigerant lines run between the two units. The thermostat, mounted on a wall, is the first thing a contractor checks when the system is not responding.
The drawing shows a typical heat pump layout, and a licensed contractor determines which parts apply to your specific house and situation.
