Sizing a heat pump for Webster Parish starts with what happens at the cold end of the heating season, not the mild weeks on either side of it. Homes in Webster Parish, LA run heat about five months a year, from November through March. A heat pump loses capacity as outdoor temperatures drop, so the coldest nights in January and February are what the contractor has to design around. A system undersized for those nights leans on electric backup heat strips to close the gap, which works but costs more to run. The load calculation a contractor runs before quoting is how that gap gets found before the equipment goes in.
Ductwork laid out for a different generation of central heating does not automatically carry a heat pump efficiently, and in Webster Parish a large share of the housing was built when that older generation was standard. Half the homes in Webster Parish, Louisiana were built in 1973 or earlier (2020-2024 ACS 5-year). A contractor sizing a heat pump here has to assess what the existing duct system will actually deliver, not just whether ducts are present. Routing, sizing, and leakage all feed into whether the installed unit performs as rated or works against itself from the first season.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners notice first. It sits outside the house on a pad or wall bracket and holds the compressor and the outdoor coil, which do the work of pulling heat from the air. Inside the house, the air handler mounts in a utility closet, basement, or attic and circulates conditioned air through the home.
A refrigerant line set runs between the two units, connecting them through a small penetration in the wall. The thermostat goes on an interior wall and gives the homeowner control over the whole system. A condensate drain line routes moisture that the indoor coil pulls from the air to a floor drain or outdoors.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece is positioned and connected in your home.
