Step 1 of 3: Equipment

Sizing a heat pump for Lee County means accounting for what happens at the coldest end of the heating season, not just the average of it. Homes in Lee County, AR run heat about five months a year, from November through March. A heat pump's capacity drops as outdoor temperatures fall, so a unit that covers the house comfortably in November may fall short on the hardest February nights. A contractor running a load calculation here has to establish what backup heat the system needs and how it is wired, because that gap is real and the resistance coils that fill it draw heavily on the service panel. Ductwork condition matters too, since heat delivered inefficiently through leaky runs puts extra hours on the compressor.

Ductwork in a house this age was laid out for whatever system was running when the house was new, and that system is almost certainly gone. Half the homes in Lee County, Arkansas were built in 1973 or earlier (2020-2024 ACS 5-year). A heat pump installation here turns on whether the existing duct runs move enough air for the new unit and whether the electrical service will carry the load it draws. Those are separate questions, and both have to be answered before a contractor can price the job.

What Gets Installed With a New Heat Pump

The outdoor unit is the piece a homeowner sees first, sitting on a concrete pad or wall bracket outside the house. It holds the compressor and the outdoor coil, and it is where the system does the work of moving heat between the refrigerant and the outside air. Inside, the air handler mounts in a utility closet, attic, or basement and pushes conditioned air through the home.

A refrigerant line set runs between the two units, carrying refrigerant through insulated copper tubing that passes through an exterior wall. The thermostat goes on an interior wall and gives the homeowner control over the system. A condensate drain line runs from the air handler to a floor drain or outside, carrying away the 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.
