A heat pump quoted and installed for this area has to fit the actual heating and cooling demand of the house, and that demand is shaped in part by how often the system gets pushed hard. 107 severe weather events were recorded in Henry County, Iowa between 2015 and 2024. At roughly the midpoint of counties nationwide, Henry County sees enough severe weather to make it a real variable in sizing, but not so much that climate load overrides every other decision. What a contractor has to get right first is the load calculation for the specific structure, because an undersized or poorly sited unit runs harder regardless of the season.

Ductwork installed for a furnace and central air setup handles airflow differently than what a heat pump needs, and in Henry County that gap between original design and current equipment is the first thing a contractor has to resolve. Half the homes in Henry County, Iowa were built in 1968 or earlier (2020-2024 ACS 5-year). Houses built around that era were ducted for high-temperature supply air, and a heat pump moves more air at a lower temperature to achieve the same result. Ducts that are undersized, poorly sealed, or laid out for the older logic can limit what a new system delivers regardless of its rated output. The electrical service is a separate check. A contractor will look at the panel before anything else gets quoted.
What a Heat Pump Installation Covers

The outdoor unit sits on a pad beside the house and holds the compressor and coil that do the system's main work. Inside, the air handler mounts in a mechanical room, basement, or closet and moves conditioned air through the home. These two units are what a contractor sets in place.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two and carrying the working fluid between them. A thermostat goes on an interior wall where it reads the living space and signals the system to run. Both pieces are part of what a full installation puts in.
