Step 1 of 3: Equipment

Sizing a heat pump for Avoyelles Parish means settling two questions before the quote is written: what the compressor can deliver on the coldest nights, and where backup heat has to pick up the slack. Homes in Avoyelles Parish, LA run heat about five months a year, from November through March. A heat pump loses capacity as outdoor temperatures drop, so the heating season is where the system is most likely to be found short. A contractor who skips a proper load calculation here can leave the resistance backup carrying more than its share from day one, which shortens both elements and drives up the electric bill every cold month.

Ductwork sized and routed for an older central system does not automatically carry a heat pump's air-handling demands, and that gap is where most of the real installation work in Avoyelles Parish sits. Half the homes in Avoyelles Parish, Louisiana were built in 1980 or earlier (2020-2024 ACS 5-year). A house built to that point was ducted for equipment that drew and distributed air differently, so a contractor here measures static pressure and checks branch runs before the new unit is ever ordered. What they find in those ducts, not the equipment selection itself, is what sets the scope and the price.

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 heat gets drawn from or released to the outside air. Inside, the air handler mounts in a utility space, attic, or closet and moves conditioned air through the home.

A refrigerant line set runs between the two units, connecting the outdoor and indoor sides of the system. A thermostat goes on an interior wall where it can read the home's temperature and tell the system when to run. A condensate drain line ties into the air handler to carry away any moisture the indoor coil pulls from the air.

The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.
