A heat pump working through cold months puts its reversing valve through repeated switches between heating and cooling modes, and the defrost board cycles every time the outdoor coil ices. Those are the parts that carry the load in a genuine heating season. Homes in Little River County, AR run heat about five months a year, from November through March. A contractor quoting a repair in Little River County looks at both before pricing a compressor replacement, because a failed reversing valve presents with symptoms close enough to compressor failure that a misread costs the homeowner a full system swap they did not need.
Ductwork in stock this old was put in for systems that are no longer made, and what it has accumulated, and how it has been patched and rerouted over the decades since, shapes what a repair job actually requires once the unit is open. Half the homes in Little River County, Arkansas were built in 1980 or earlier (2020-2024 ACS 5-year). A contractor pulling panels on a heat pump here has to determine whether the parts that system takes are still in production, and whether the surrounding infrastructure will carry the repair or add to the scope of it.
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 condenser coil. These are the parts a contractor reaches first when the system stops heating or cooling properly. A failed compressor, a refrigerant leak at the coil, or a worn contactor in that cabinet are common reasons a heat pump stops doing its job.
Inside the house, the air handler contains the blower motor and the evaporator coil. The reversing valve, which tells the system whether to heat or cool, lives in the outdoor unit and gets checked when the system runs but delivers the wrong kind of air. The expansion valve and refrigerant lines connecting both units are also on the contractor's list.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which parts apply to your specific house and situation.

Severe Weather Events in Little River County
Weather puts real load on heat pump equipment. The harder a system works to hold a set temperature against what comes through, the more stress its components carry over time, and that stress is what repair work addresses.
