A contractor quoting a heat pump installation in Pushmataha County has to decide how much the local weather record should shape the spec. 63 severe weather events were recorded in Pushmataha County, Oklahoma between 2015 and 2024. At that rate, severe weather here is an occasional disruption rather than a standing operating condition, so oversizing a system to absorb weather load would be the wrong response to a real but limited record. The variables that drive sizing decisions are the house itself: insulation, duct condition, and how well the original install was done. Those are what a contractor measures before any equipment gets ordered.
Ductwork laid down for a system that predates today's heat pump technology carries assumptions about airflow, sizing, and return-air placement that a modern unit was not designed around. Half the homes in Pushmataha County, Oklahoma were built in 1982 or earlier (2020-2024 ACS 5-year). A contractor scoping a heat pump installation here looks hard at what is already in the walls and ceilings before anything else, because duct runs built for older equipment often need rerouting or resizing to move conditioned air the way a heat pump expects. The electrical service is the second question: older panels frequently require an upgrade to handle the load a heat pump draws. What the house already contains sets 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 condenser coil. The indoor air handler mounts inside, usually in a closet, attic, or mechanical room, and it is the piece that moves conditioned air through the home. Together, these two units are what a contractor sets in place during a new install.
A refrigerant line set runs between the outdoor unit and the air handler, and a condensate drain line carries moisture away from the indoor side. A thermostat mounts on an interior wall and serves as the control point for the whole system.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house and its setup.
