A contractor quoting a heat pump install in Monona County starts from what heating and cooling loads this climate puts on a system year after year, not from storm tallies. 54 severe weather events were recorded in Monona County, Iowa between 2015 and 2024. At that rate, severe weather is an event here, not a standing condition, which means the variables that drive installation decisions are local temperature swings, soil conditions for ground-source work, and the quality of the duct system inside the house. A unit sized wrong for this climate will underperform regardless of how many storms the county sees.
Ductwork laid down for a furnace and window units was designed around a different kind of air movement than a heat pump requires. Half the homes in Monona County, Iowa were built in 1956 or earlier (2020-2024 ACS 5-year). A contractor pricing a heat pump install in this county spends real time on what the existing duct system will actually carry, because that answer shapes the scope more than the equipment selection does. Panels from the same era sometimes need assessment too, depending on what the new unit draws. The box gets priced after the house gets read.
What a Heat Pump Installation Covers
The outdoor unit sits on a concrete pad or wall bracket beside the house and holds the compressor and coil that do the bulk of the work. Inside, the air handler mounts in a utility space, basement, or closet and circulates conditioned air through the home. Together, these two cabinets are what a contractor is placing and connecting.
A refrigerant line set runs between the two units through a small penetration in the wall, carrying the charge that links the system. A thermostat goes on an interior wall where it can read the living space accurately and give the homeowner control over the whole system.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.
