Sizing a heat pump for Pontotoc County starts with what the climate actually demands of the equipment, and the weather record here is not a mild one. 197 severe weather events were recorded in Pontotoc County, Oklahoma between 2015 and 2024. At that rate, severe weather is a standing condition of operating in this county, not an occasional disruption. A contractor quoting an install here factors that load into equipment selection, refrigerant line placement, and how well the envelope is sealed, because a unit sized for moderate conditions will run harder than it was built to and wear its components down faster. The install has to hold against what this area routinely delivers.
Ductwork laid in for a conventional furnace was sized around that furnace's airflow, and a heat pump moves air differently. Whether the existing runs can carry what a new system needs is the question a contractor has to answer before the unit itself is even priced. Half the homes in Pontotoc County, Oklahoma were built in 1978 or earlier (2020-2024 ACS 5-year). That profile means a substantial share of the houses in this county are carrying ductwork that has never been asked to do what a heat pump asks of it, and a contractor quoting the job will open and measure those runs rather than assume they transfer.
What a Heat Pump Installation Covers
The outdoor unit sits on a pad beside the house and holds the compressor and the coil that exchange heat with the outside air. Inside, the air handler mounts in a utility space, closet, or attic and moves conditioned air through the home. Together these two units are what a new installation puts in place.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two halves of the system. A thermostat goes on an interior wall where it reads the living space and tells the system when to run. The condensate drain line carries moisture away from the air handler to a floor drain or outside.
The drawing shows a typical layout, and a licensed contractor determines what the installation requires in your specific home.
