A contractor quoting a heat pump installation in Custer County starts from what this climate actually demands, because the sizing decisions that work in quieter parts of the country do not translate here without adjustment. 183 severe weather events were recorded in Custer County, Oklahoma between 2015 and 2024. At that rate, severe weather is a regular part of the operating environment, and a system spec'd to catalog minimums will be working against the conditions it was put into from the start. Equipment selected for this county needs headroom built in, and the quality of the install itself carries more weight than it does somewhere the load is lighter.
Ductwork laid down for an older furnace or window units was never sized for the airflow a heat pump needs, and in Custer County's housing stock that gap is where an installation job either gets complicated or does not. Half the homes in Custer County, Oklahoma were built in 1978 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump here opens wall cavities and crawlspaces to find out what the existing runs can carry before the equipment conversation starts. The electrical panel is the second question, since the service a house received at construction often falls short of what a modern heat pump draws.
What a Heat Pump Installation Puts in Your Home
The outdoor unit sits on a pad beside the house and holds the compressor and one set of coils. Inside, the air handler mounts in a mechanical room, closet, or attic and moves conditioned air through the home. These two units are the core of what gets installed.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid through both. A thermostat goes on an interior wall and gives you control over the whole system. A condensate drain line runs from the air handler to a suitable discharge point.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.
