Sizing a heat pump for Garfield County starts with understanding what the equipment will be asked to carry here, year after year. 223 severe weather events were recorded in Garfield County, Oklahoma between 2015 and 2024. At that rate, severe weather is a standing operating condition, and a contractor who quotes without accounting for it will undersize the unit or skip details in the install that protect it when conditions turn. Refrigerant line routing, electrical connections, and mounting all hold up differently on a system that runs under real load than on one that sits easy most of its life.
Ductwork sized and routed for a furnace-and-AC setup carries air at different volumes and static pressures than a heat pump expects. Half the homes in Garfield County, Oklahoma were built in 1970 or earlier (2020-2024 ACS 5-year). That gap between when these houses were built and what a contractor is now being asked to install in them is where most of the real assessment work happens. An electrician's findings matter too, since the service capacity in a house that old shapes what the outdoor unit can draw. What a contractor quotes on a heat pump job here is grounded in what they find in the walls and the panel, not in the equipment spec sheet alone.
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 heat exchange coil, the two components that do the heaviest work. Inside, an air handler mounts in a utility space, closet, or attic and moves conditioned air through the home. These are the two main pieces a homeowner buys when they buy a heat pump.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two halves of the system through the wall or floor. A thermostat mounts on an interior wall and gives the homeowner control over when and how the system runs.
The drawing shows a representative layout, and a licensed contractor determines exactly how each piece is placed and connected in your specific home.
