On a heat pump, the refrigerant circuit works hardest when outdoor temperatures are lowest, and that is exactly when Cumberland County asks the most of it. Homes in Cumberland County, NJ run heat about seven months a year, from October through April. A contractor diagnosing a struggling system here looks at refrigerant charge, defrost board behavior, and compressor draw before anything else, because those are the components that have been cycling through the coldest months. A unit that was sized or charged slightly off spec will show the gap in its performance readings before it shows it anywhere else.
Ductwork and wiring in houses this old were sized and routed for systems that are no longer made, and what a contractor finds once a heat pump is opened often reflects that gap. Half the homes in Cumberland County, New Jersey were built in 1969 or earlier (2020-2024 ACS 5-year). Parts that have been adapted, spliced, or substituted over the decades show up as conditions the repair has to work around, and whether a replacement component for a unit of that vintage is still in production shapes how the job goes as much as the fault itself.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is usually the first thing a homeowner notices, and it is often where a contractor starts. That cabinet houses the compressor and one set of coils. When the compressor fails, the system stops moving heat altogether. When the coils are damaged or badly fouled, the unit strains and the house either stays cold or stays hot.
Inside the house, the air handler holds the second set of coils and the blower that pushes conditioned air through the home. A refrigerant line set runs between the two units, and an expansion valve sits along that path to regulate flow. The air handler and the valve are common places for a contractor to look when the outdoor unit checks out fine but the system still underperforms.
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.
