Sizing a heat pump in Sequoyah County starts with what the climate asks of the equipment, because the answer shapes every specification a contractor puts on paper. 107 severe weather events were recorded in Sequoyah County, Oklahoma between 2015 and 2024. At that rate, severe weather is a regular operating condition rather than an exception, and a contractor who ignores it will size the system for conditions that do not exist here. Refrigerant capacity, coil ratings, and the electrical supply all get set at installation and are hard to correct later, so getting those figures right against the actual local load is the whole job.
Ductwork sized for a different era of equipment shapes what a heat pump installation actually costs in Sequoyah County. Half the homes in Sequoyah County, Oklahoma were built in 1986 or earlier (2020-2024 ACS 5-year). A contractor quoting a new system has to look at what the existing duct runs can handle before the equipment selection means anything. Flex runs that were adequate for a gas furnace blower may need to be resized or rerouted to carry the airflow a heat pump delivers efficiently. The electrical service is a separate check. What a homeowner gets quoted depends heavily on what those two assessments turn up.
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. The indoor air handler mounts inside, usually in a closet, attic, or utility room, and moves conditioned air through the home. Together, these two units are what a new heat pump installation places.
A refrigerant line set runs between the outdoor and indoor units, connecting them through a small penetration in the wall. A thermostat goes on an interior wall where it reads the home's temperature and signals the system to run. Each of these pieces is part of what gets put in during a full installation.
The drawing shows a typical layout, and a licensed contractor determines what the configuration looks like in your specific home.

Severe Weather Events in Sequoyah County
Oklahoma's climate puts real demands on heating and cooling equipment, and Sequoyah County gets its share of what the sky can deliver. A heat pump sized and installed for local conditions handles those swings more reliably than one spec'd for somewhere else.
