A heat pump install in McCurtain County has to account for what this area actually puts systems through. 207 severe weather events were recorded in McCurtain County, Oklahoma between 2015 and 2024. At that rate, severe weather is a standing condition here, and a contractor sizing and placing a heat pump treats it as a design input rather than an afterthought. Refrigerant line routing, unit placement, and the quality of the electrical connections all carry more weight in a county where the equipment faces repeated stress loads. A spec that works on paper in a moderate climate can fall short here before the warranty period is up.
The ductwork and the electrical panel in a house are not sized once and then forgotten. Half the homes in McCurtain County, Oklahoma were built in 1983 or earlier (2020-2024 ACS 5-year). A heat pump draws more current than the resistance heating or window units many of those houses were wired around, and a panel that was adequate for decades can fall short of what a new installation requires. A contractor quoting a heat pump here opens the electrical panel early, because what it contains changes the scope of the job before any equipment is selected.
What a Heat Pump Installation Covers
The outdoor unit sits on a pad beside the house and holds the compressor and the condenser coil, which are the pieces that move heat between the refrigerant and the outside air. Inside, the air handler mounts in a utility space, closet, or attic and pushes conditioned air through the home. Together these two units do the main work of the system.
A copper refrigerant line set runs between the outdoor unit and the air handler, carrying refrigerant back and forth between them. The thermostat mounts on an interior wall and tells the system when to run. A condensate drain line runs from the air handler to a drain point, clearing the moisture the indoor coil pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.
