A heat pump running through a hard Missouri winter puts its reversing valve through repeated thermal cycling, and Howell County winters are long. Homes in Howell County, MO run heat about seven months a year, from October through April. By the time a system shows a fault, the reversing valve and the refrigerant line connections have already absorbed a season's worth of starts, stops, and temperature swings that drop well below the point where a heat pump's capacity begins to fall off. A contractor called out for a repair here checks those components before pricing anything else, because worn valve seals or stressed connections produce symptoms that look like compressor failure until the system is open.
Ductwork in a house carries the history of every system that has run through it, and in Howell County that history tends to be long. Half the homes in Howell County, Missouri were built in 1982 or earlier (2020-2024 ACS 5-year). A heat pump sitting in stock that old has likely outlasted at least one previous unit, and the refrigerant lines, electrical connections, and internal components a contractor opens may reflect repairs done under conditions and standards that no longer apply. Parts availability is the variable that drives scope here: if what a contractor finds inside the unit takes components that are no longer manufactured, the repair estimate changes shape entirely before a single part is ordered.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize, a metal cabinet sitting on a pad beside the house that holds the compressor and the outdoor coil. The compressor is where most repair calls begin. When it fails, the system runs but moves no heat. The outdoor coil, wrapped around the cabinet's interior, is where heat is absorbed or released, and a damaged or dirty coil can mimic a compressor problem.
Inside the house, the air handler holds the indoor coil and the blower. The indoor coil handles the other half of the heat exchange, and a refrigerant leak there often shows up first as ice or weak airflow. The blower pushes conditioned air into the home, and a failing blower motor is something a contractor checks early. The reversing valve, which sits inside the outdoor unit, switches the system between heating and cooling, and a stuck valve is a common reason a heat pump heats when it should cool or does neither.
The drawing shows a general layout of these components, and a licensed contractor determines what applies to the specific equipment and configuration in your home.
