A contractor quoting a heat pump installation here has to work out what the system will face at the cold edge of the season, not just through the comfortable middle of it. Homes in West Baton Rouge Parish, LA run heat about five months a year, from November through March. Heat pump capacity drops as outdoor temperatures fall, so a unit that handles most of November through February without trouble can fall short on the coldest nights, when the house needs the most from it. The contractor's load calculation has to account for that gap and establish whether supplemental heat belongs in the design.
Ductwork built around a different kind of system presents the real unknown in a heat pump installation here. Half the homes in West Baton Rouge Parish, Louisiana were built in 1993 or earlier (2020-2024 ACS 5-year). That means a contractor opening a home in this parish is likely to find ducts that were sized and routed for equipment with a different airflow profile than a heat pump carries. Whether those ducts can handle the new system's delivery pattern without pressure loss or hot spots is what gets measured before anything else is priced. The electrical service is a separate check: older panels were not wired for the draw a modern heat pump puts on them.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, sitting on a pad beside the house. It holds the compressor and the outdoor coil, which do the core work of moving heat between the refrigerant and the outside air. Inside the house, 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 them through the wall or floor. A thermostat goes on an interior wall where it can read the living space accurately, and a disconnect box mounts near the outdoor unit to give the contractor a safe shutoff point for service.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions of your particular house.
