Sizing a heat pump for Dallas County starts with what the outdoor coil faces at the hard end of winter, not at the average. Homes in Dallas County, AR run heat about five months a year, from November through March. As temperatures drop toward freezing, a heat pump's capacity falls while the house's heat loss climbs, and the gap between those two lines is where backup heat fills in. A contractor has to establish where that crossover point sits for this house before they can specify the right equipment. Get that wrong and the backup resistance elements run constantly through January and February, which a homeowner reads as high electric bills but a service tech reads as a unit that was never right for the load.
Ductwork sized for a different era of equipment is the first thing a contractor opens when quoting a heat pump installation in Dallas County. Half the homes in Dallas County, Arkansas were built in 1978 or earlier (2020-2024 ACS 5-year). That means much of the existing duct layout was designed around systems with different airflow demands, and a contractor has to check whether it moves enough air, in the right distribution, before the new unit goes in. The electrical service gets the same scrutiny. A panel that carried the original load may not carry what a heat pump draws, and finding that out early changes the scope of the job.
What a Heat Pump Installation Puts in Your Home
The outdoor unit sits on a pad beside the house and holds the compressor and the coil that exchanges heat with the outside air. The indoor air handler mounts inside, most often in a utility closet, basement, or attic, and circulates conditioned air through the living space. Together these two units are the core of what a contractor installs.
A refrigerant line set runs between the outdoor and indoor units, carrying refrigerant through insulated copper tubing that passes through an exterior wall. A thermostat mounts on an interior wall and gives the homeowner control over the system. The condensate drain line runs from the air handler to a floor drain or outside, removing moisture pulled from the indoor air.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece applies to your house.
