Sizing a heat pump for Assumption Parish starts with the heating load, not the cooling load. Homes in Assumption Parish, LA run heat about five months a year, from November through March. As outdoor temperatures fall, a heat pump's capacity falls with them, which means a unit that looks adequate on paper can leave the backup resistance heat carrying most of the work on the coldest nights. A contractor running a proper load calculation here sets the heat pump to cover as much of that heating demand as the equipment can handle efficiently, then specifies backup heat for the gap. Get that balance wrong on installation day and the resistance strips run far more than they were designed to.
Ductwork routed for an older system does not automatically carry a heat pump well. The layout, the sizing of the runs, and whether the returns are placed to handle the airflow a heat pump moves are questions a contractor has to answer about the specific house before the unit itself gets priced. Half the homes in Assumption Parish, Louisiana were built in 1983 or earlier (2020-2024 ACS 5-year). A house that age was ducted for whatever was running at the time, and a heat pump asks something different of that ductwork. What the contractor finds when they trace those runs decides whether the existing system carries the new one or needs changes first.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a concrete pad or bracket beside the house, and it holds the compressor and the outdoor coil that do the main work of moving heat. Inside the home, the air handler sits in a utility closet, attic, or basement and pushes conditioned air through the house.
A refrigerant line set runs between the two units, carrying refrigerant back and forth through insulated copper tubing that passes through an exterior wall. A thermostat mounts on an interior wall and gives the homeowner control over the whole system.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions of your specific home.
