A contractor quoting a heat pump installation in Delaware County has to account for what the climate actually asks of a system here before settling on equipment size or placement. 117 severe weather events were recorded in Delaware County, Oklahoma between 2015 and 2024. At that rate, severe weather is a standing operating condition, and a unit sized or mounted for a milder load will be running against the wrong assumptions from the first season. Refrigerant line routing, unit placement, and equipment ratings all follow from what the weather here puts a system through, not from what a catalog recommends for a generic install.
Ductwork in houses this old was sized and routed for whatever heated them originally, and a heat pump moves air differently than what most of that stock started with. Half the homes in Delaware County, Oklahoma were built in 1987 or earlier (2020-2024 ACS 5-year). A contractor quoting a new heat pump here checks the existing ducts before pricing the unit, because undersized or poorly routed ductwork limits what the new system can deliver regardless of the equipment chosen. Electrical service gets the same look: the panel has to carry the load the heat pump draws, and panels from that era vary widely.
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 indoor air handler mounts inside, usually in a utility closet, basement, or attic, and moves conditioned air through the home. Together these two pieces are what a new heat pump installation places.
A refrigerant line set runs between the two units, connecting them through a small penetration in the wall. A thermostat goes on an interior wall where it can read the living space, and a condensate drain line routes moisture away from the air handler.
The drawing shows a representative layout, and a licensed contractor determines what fits the specifics of your house.

Severe Weather Events in Delaware County by Year
Local weather puts real demands on heating and cooling equipment, and those demands shape what a heat pump in this area has to handle over its working life. How hard a system runs, how long it lasts, and what capacity it needs to carry are all local questions.
