Sizing a heat pump for Lyon County means working out what the compressor carries through a heating season that is not brief. Homes in Lyon County, KS run heat about seven months a year, from October through April. Capacity on a heat pump drops as outdoor temperatures fall, so the refrigerant circuit and the reversing valve are under their heaviest load on the coldest days of those months, when outdoor temperatures resist the heat exchange the system depends on. A contractor has to calculate that sustained cold-weather demand before committing to a unit, because an undersized system runs longer cycles, which wears the compressor faster than the manufacturer's ratings assume. Back-up heat sizing follows from the same calculation.
Ductwork sized for a furnace and central air setup carries air in a pattern heat pumps do not share. Half the homes in Lyon County, Kansas were built in 1970 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump here measures what the existing ducts can move and at what static pressure, because a system installed against undersized or poorly configured ductwork runs short of the efficiency it was rated for. The electrical service gets checked for the same reason. Both questions belong to the house before any equipment gets priced.
What a Heat Pump Installation Covers in Your Home
The outdoor unit sits on a pad beside the house and holds the compressor and the coil that exchange heat with the outside air. The indoor air handler mounts inside, most often in a utility closet, basement, or attic, and moves conditioned air through the home. Together these two units are the core of what a contractor installs.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two and carrying the working fluid that lets heat move between them. A thermostat, mounted on an interior wall, is the control point the homeowner interacts with every day. The contractor also installs a disconnect box near the outdoor unit as part of the electrical connection to the system.
The drawing shows a general layout of these components, and a licensed contractor determines exactly how each one is positioned and configured in your specific house.
