A contractor quoting a heat pump installation in Livingston Parish has to work out two things before settling on equipment: how cold the outdoor air gets at the bottom of winter, and how much capacity the heat pump loses at that point. Homes in Livingston Parish, LA run heat about five months a year, from November through March. That capacity drop is what makes sizing a local question rather than a catalog exercise. A heat pump that looks adequate on paper can fall short on the coldest nights, leaving the backup resistance elements to carry the load the compressor cannot. A contractor who skips the low-temperature performance curve leaves the homeowner paying for that gap every heating season.
Ductwork laid for a central air system built around different equipment does not automatically carry a heat pump without review. A contractor installing here has to verify that what is already behind the walls moves enough air for the new unit and that the electrical service can handle the load. Half the homes in Livingston Parish, Louisiana were built in 2002 or earlier (2020-2024 ACS 5-year). That puts the existing duct layout and the panel at the center of the quote, before the outdoor unit gets selected.
What Gets Installed With a New Heat Pump
The outdoor unit sits on a pad outside the house and holds the compressor and the condenser coil. The indoor air handler mounts inside, often in a closet, attic, or mechanical room, and pushes conditioned air through the home. Together these two cabinets form the core of the installed system.
A refrigerant line set runs between the two units through a small penetration in the wall, carrying refrigerant from outside to inside and back. A thermostat goes on an interior wall and gives the homeowner control over the whole system. Some installations also include an auxiliary electric resistance strip inside the air handler to supplement heating output in colder conditions.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house and how each piece is positioned within it.
