Sizing a heat pump for this parish starts with understanding where outdoor temperatures will push the unit past its heating capacity. Homes in East Feliciana Parish, LA run heat about five months a year, from November through March. When temperatures drop through those winter months, a heat pump's output falls, and a unit that looks adequate on paper can leave the backup heat strip carrying a load it was meant to supplement. A contractor working an installation here has to run a proper load calculation and set a realistic balance point before specifying equipment, because undersizing shows up in January, not in a test run on a mild afternoon.
Ductwork sized for a previous generation of cooling equipment is what decides whether a heat pump installation is straightforward or not. Half the homes in East Feliciana Parish, Louisiana were built in 1989 or earlier (2020-2024 ACS 5-year). A house built in that era was almost certainly ducted for a system that draws and distributes air differently from what a heat pump requires, which means the duct layout gets measured and tested before the new unit is ever ordered. If the runs are undersized or the returns are too few, that gets addressed first. The electrical service gets the same look, since panels from that period were not built to carry the load a modern heat pump draws.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner notices first. It sits on a pad outside the house and holds the compressor and the outdoor coil, which together do the heavy work of moving heat between inside and out. The indoor air handler mounts in a utility space, closet, or attic and pushes conditioned air through the home.
A refrigerant line set runs between the two units, connecting the outdoor pad to the air handler through the wall or ceiling. A thermostat goes on an interior wall where it reads the temperature and tells the system when to run.
The drawing shows a typical layout, and a licensed contractor determines what applies to this particular house.
