Sizing a heat pump for this parish starts with what the heating season actually demands of the outdoor unit. Homes in Iberville Parish, LA run heat about five months a year, from November through March. As temperatures drop through January and February, a heat pump's capacity falls while the house's heat loss stays constant, and a unit that tests fine on a mild December day may be leaning on its backup elements through the hardest weeks. A contractor has to establish that gap before committing to equipment, because undersizing it at installation is a decision the homeowner lives with every winter the system runs.
Ductwork laid out for older central systems carries assumptions about airflow and distribution that a heat pump does not share, and when that ductwork runs through the house a contractor is quoting, it becomes the first variable they have to resolve. Half the homes in Iberville Parish, Louisiana were built in 1986 or earlier (2020-2024 ACS 5-year). Stock built in that era was ducted around equipment with different delivery pressures and return configurations, and whether those runs can carry a modern heat pump without modification is something a contractor has to open and measure, not assume. Electrical service from the same period may also need evaluation before a panel can support the new load.
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, and it is where the system pulls heat from or releases it to the outside air. The indoor air handler mounts inside, most often in a utility closet, basement, or attic, and it moves conditioned air through the home.
A refrigerant line set runs between the two units, carrying refrigerant back and forth through insulated copper tubing. A thermostat goes on an interior wall and gives the homeowner control over temperature settings. Some installations also include a separate disconnect box mounted near the outdoor unit, which gives a technician a local shutoff point.
The drawing shows a general layout of these components, and a licensed contractor determines exactly how each one is positioned and connected in your specific home.
