Sizing a heat pump in Columbia County means accounting for what happens at the cold edge of the heating season, not just the middle of it. Homes in Columbia County, AR run heat about five months a year, from November through March. A heat pump loses capacity as outdoor temperatures drop, so a system that keeps up in December can fall short in January, leaving the backup heat source to carry the load. A contractor has to know what that backup source is, whether it exists at all, and whether the service panel can support it, before the equipment is selected.
Ductwork laid out for an older heating system carries assumptions about airflow that a heat pump does not share. Half the homes in Columbia County, Arkansas were built in 1981 or earlier (2020-2024 ACS 5-year). That vintage of construction means a contractor sizing a new heat pump is pricing against what the existing duct runs will and will not carry, before the unit itself enters the conversation. Where the ductwork cannot handle the load, the electrical service gets checked next. Both have to be settled before the equipment choice matters.
What a Heat Pump Installation Puts in Your Home
The outdoor unit is the piece most homeowners notice first. It sits on a pad outside the house and holds the compressor and one set of coils. Inside, an air handler mounts in a utility space, closet, or attic and circulates conditioned air through the home.
A refrigerant line set runs between the two units, connecting the outdoor pad to the air handler. A thermostat goes on an interior wall and serves as the control point for the whole system. Some installations also include a supplemental heat strip inside the air handler for cold snaps.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the specifics of your house.
