Takes about a minute. No obligation.
A contractor quoting a heat pump installation in Lafayette Parish has to work out how cold the coldest nights actually get before settling on a unit and whether backup resistance heat belongs in the plan. Homes in Lafayette Parish, LA run heat about five months a year, from November through March. That heating window is short enough that the compressor spends most of the year on cooling duty, but the weeks when temperatures fall hardest are exactly when a heat pump's output drops. An undersized unit runs at full capacity through those nights with no headroom left. Sizing has to account for that floor, not for the average.
Ductwork and electrical service are what decide how a heat pump installation goes in this parish, and in stock this age the electrical side is where the real question sits. Half the homes in Lafayette Parish, Louisiana were built in 1988 or earlier (2020-2024 ACS 5-year). A service panel put in around that time was sized for the load the house carried then, and a heat pump draws more current than whatever it is replacing. A contractor has to open the panel and read what is actually there before a quote means anything, because an undersized service requires its own separate work before the heat pump goes in.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner notices first: a metal cabinet set on a concrete pad or bracket outside the house, holding the compressor and one of the two coils. Inside, an air handler mounts in a closet, utility room, or attic and moves conditioned air through the home. These two units are what a new installation puts in place.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two coils so the system works as one. A thermostat goes on an interior wall and gives the homeowner control over the whole system. A condensate drain line carries moisture from the air handler to a safe discharge point.
The drawing shows a typical layout, and a licensed contractor determines what applies to this specific house.
