A contractor quoting a heat pump installation in Adair County has to treat the local climate as a design input, not a footnote. 69 severe weather events were recorded in Adair County, Oklahoma between 2015 and 2024. At that rate, severe weather is a standing feature of operating here, present enough that the refrigerant line routing, the pad placement, and the unit's rated capacity all need to reflect what the equipment will actually face season after season. A system sized for a milder load will cycle harder, reach its limits sooner, and cost more to run than one the contractor sized for this county specifically.
Ductwork sized for a different era of equipment is what a contractor runs into in much of Adair County's housing stock. Half the homes in Adair County, Oklahoma were built in 1982 or earlier (2020-2024 ACS 5-year). A heat pump moves air differently than what many of these houses were originally built around, and ducts laid out for that older logic can restrict airflow, create pressure problems, or simply run in the wrong places for the new system to work as it should. The electrical panel gets checked for the same reason. Neither of those is a quick visual inspection; both require the contractor to get into the house before a quote means anything.
What a Heat Pump Installation Covers
The outdoor unit sits on a pad outside the house and holds the compressor and condenser coil, which do the core work of moving heat between inside and out. The indoor air handler mounts inside, usually in a closet, utility room, or attic, and pushes conditioned air through the home.
A refrigerant line set runs between the two units, carrying the working fluid that connects them. A thermostat goes on an interior wall where it reads the living space and tells the system when to run.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.

Severe Weather Events in Adair County
Weather stress is one of the real workload drivers for heating and cooling equipment, and Adair County's conditions shape how hard a heat pump has to work year-round. A contractor sizing or installing equipment here is working with local weather as a baseline, not a national average.
