Sizing a heat pump for Tensas Parish starts with what the equipment has to do on the coldest nights, not on the average ones. Homes in Tensas Parish, LA run heat about five months a year, from November through March. A heat pump's capacity drops as outdoor temperatures fall, so a unit that covers the house comfortably in November can fall short by February, pulling in electric resistance backup heat to compensate. A contractor has to work out where that crossover point sits for this house before they can choose the right equipment. Get that calculation wrong and the backup heat carries a bigger share of the season than the heat pump does, which erases the efficiency the homeowner was installing for.
Ductwork in a house this old was laid out for a system that is no longer in it, and a heat pump puts different demands on that distribution network than what originally ran through it. Half the homes in Tensas Parish, Louisiana were built in 1972 or earlier (2020-2024 ACS 5-year). A contractor pricing a heat pump installation here has to assess what those ducts can actually move before the equipment selection means anything, because undersized or poorly routed runs will limit what even a correctly sized unit can deliver. The electrical service gets the same look: panels in houses of this vintage were not built for the loads a modern heat pump draws.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a pad beside the house, and it holds the compressor and the outdoor coil that do the core work of the system. Inside the house, the air handler sits in a utility closet, attic, or basement and pushes conditioned air through the home.
A refrigerant line set runs between the two units through the wall, carrying the working fluid that ties the outdoor and indoor sides together. A thermostat goes on an interior wall and gives the homeowner control over the whole system.
The drawing shows the general layout of these components, and a licensed contractor determines exactly what applies to your house.
