Sizing a heat pump for Floyd County starts with what the equipment will actually run against, not what a catalog spec assumes. 146 severe weather events were recorded in Floyd County, Iowa between 2015 and 2024. A contractor who skips a proper load calculation here is quoting for a different county. The refrigerant circuit, the backup heat strip, and the coil surface area all get specified against local demand, and local demand here is not light. Undersizing costs the homeowner in efficiency and in wear from the first winter on.
Ductwork laid out for a furnace does not automatically carry a heat pump's airflow requirements, and in Floyd County that gap between original design and new equipment is where most installation work lives. Half the homes in Floyd County, Iowa were built in 1958 or earlier (2020-2024 ACS 5-year). That means a contractor pricing a heat pump here is measuring and assessing the existing duct runs before the equipment selection is final, because undersized or poorly routed ductwork limits what the new system can deliver regardless of the unit on the pad. The electrical service gets the same look, since panels from that era were not sized for the loads modern heat pumps draw.
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 refrigerant coil that do the core work of moving heat. Inside, an air handler mounts in a utility space, a closet, or an attic and pushes conditioned air through the home. These two pieces are what a new installation puts in place.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two through a wall or floor penetration. A thermostat goes on an interior wall where it reads the temperature of the living space and signals the system to run.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions in your house.

Severe Weather Events in Floyd County
Heat pump performance is shaped by what the local climate demands of it year after year. Weather stress accumulates, and equipment sized and installed for the conditions here handles that load differently than gear chosen without it in mind.
