A heat pump running a full heating season puts its refrigerant circuit through repeated pressure swings, and the defrost board cycles constantly whenever outdoor temperatures drop. Homes in Perry County, AR run heat about six months a year, from November through April. The reversing valve, the defrost controls, and the low-ambient sensors are the parts that carry that load, and they are where a contractor starts on a repair call here. A compressor that has been pulling heat from cold outdoor air across half the calendar shows wear in ways a visual inspection alone will not catch, so the contractor measures pressures and temperatures before pricing any part.
A heat pump repair here begins with what the house already holds. Half the homes in Perry County, Arkansas were built in 1989 or earlier (2020-2024 ACS 5-year). Ductwork put in for an older system carries its own wear and its own geometry, and when a contractor pulls the covers off a failing unit, what the duct connections, line sets, and internal components show is what sets the scope of the job. A part that looks straightforward on a work order can read differently once the system is open and the surrounding infrastructure is visible.
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 one of the two coils. The compressor is the piece contractors look at early: when it fails, the system runs but moves no heat. The outdoor coil works alongside it, and a damaged or iced-over coil points a contractor straight to refrigerant or airflow problems.
Inside the house, the air handler contains the second coil and the blower that moves conditioned air through the home. The reversing valve sits within the refrigerant circuit and is what lets a heat pump shift between heating and cooling. When a system does one job but not the other, that valve is where the diagnosis starts.
The drawing shows the general layout of these components, and a licensed contractor determines what applies to the specific system and setup in your home.
