Sizing a heat pump for Caddo Parish means working out where the equipment loses capacity before the contractor picks a unit. Homes in Caddo Parish, LA run heat about five months a year, from November through March. Outdoor temperatures drop far enough in December and January that a unit tuned only to average winter conditions will fall behind on the hardest nights. The contractor has to set a balance point for that cold floor and specify back-up heat against it, because a system that runs undersized through a full heating season wears its compressor faster than one matched to the real load.
Ductwork laid out for a gas furnace or a window-unit era does not automatically suit a heat pump, and in Caddo Parish that mismatch is a real possibility a contractor has to measure before pricing anything. Half the homes in Caddo Parish, Louisiana were built in 1975 or earlier (2020-2024 ACS 5-year). That puts a lot of houses in a range where the ducts are doing a job they were never sized for, and whether they can carry a new system is a question answered by what a contractor finds in the attic and the crawlspace, not by the equipment spec sheet. Electrical service is the second variable. A panel that fed a smaller load may need work before a heat pump can be connected safely.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners notice first. It sits on a pad outside the house and holds the compressor and the outdoor coil, which together do the system's core work. Inside, the air handler mounts in a utility space, closet, or attic and circulates conditioned air through the home.
A refrigerant line set runs between the two units, connecting the outdoor pad to the air handler and carrying refrigerant in both directions. A thermostat goes on an interior wall and gives the homeowner control over the system. Some installations also include a supplemental electric heating element inside the air handler for the coldest stretches of the year.
