A heat pump in Hinds County runs its compressor through a genuine heating season, not just occasional cold snaps. Homes in Hinds County, MS run heat about five months a year, from November through March. Through those months, the reversing valve switches the refrigerant circuit into heating mode and holds it there, cycling on and off against outdoor temperatures that can drop well below the point where a heat pump starts to lose capacity. That repeated thermal stress is what a contractor looks at first: valve sluggishness, refrigerant charge, and whether the backup heat strip has been covering for a compressor that was already struggling before the season ended.
Ductwork in a house this old has had time to develop leaks, separated joints, and insulation that no longer does its job. A contractor opening a heat pump for repair is also, in effect, reading the condition of everything the refrigerant and airflow touch. Half the homes in Hinds County, Mississippi were built in 1974 or earlier (2020-2024 ACS 5-year). That depth of age means parts a contractor pulls out may be from a generation of components where sourcing a replacement takes real effort, and what looks like a straightforward fix can depend on what the supply chain still carries.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit holds the compressor and condenser coil, and it sits on a pad outside the house. This is where a contractor starts when a heat pump stops heating or cooling properly. A failed compressor, a refrigerant leak at the coil, or a burned contactor each shows up here first.
The air handler lives inside, usually in a closet, attic, or basement, and it pushes conditioned air through the house. It carries the evaporator coil and the blower motor, both of which a contractor will inspect when the system runs but does not perform. A reversing valve, which switches the system between heating and cooling, sits inside the outdoor unit and is a common focus during a diagnostic visit.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system and what work they require.

Severe Weather Events in Hinds County
Storm activity puts real strain on heat pumps, which run through temperature swings and power disruptions that wear components faster than routine seasonal cycling. How much stress a unit absorbs over its life is a local question, and the record below shows what the equipment in this area has been working against.
