A contractor quoting a heat pump installation in Franklin County has to size for what the equipment will actually face, not for a best-case season. 105 severe weather events were recorded in Franklin County, Iowa between 2015 and 2024. At that rate, severe weather is part of the normal workload the system carries year to year. A unit undersized or improperly staged for those demands will cycle harder and run longer than it should, putting strain on components from the start. That is why local contractors price refrigerant line routing, electrical capacity, and equipment ratings around what this area actually asks of a heat pump.
Ductwork sized and routed for a furnace does not automatically carry a heat pump's airflow requirements, and in Franklin County the gap between what the house was built for and what a contractor is being asked to install is wide. Half the homes in Franklin County, Iowa were built in 1954 or earlier (2020-2024 ACS 5-year). That means the ducts in a typical house here were designed around something different, and a contractor quoting a heat pump installation has to assess what is already in the walls and crawlspaces before the equipment choice settles anything. The electrical service matters too: older panels often need upgrading to handle what a modern heat pump draws. Those two assessments, ductwork and electrical, are where the real scope of the job lives.
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 core work. Inside, an air handler mounts in a utility space, basement, or closet and moves conditioned air through the home. Together these two units are what a contractor sets in place.
A refrigerant line set runs between the outdoor unit and the air handler, carrying the working fluid that connects both sides of the system. A thermostat goes on an interior wall where it can read the home's temperature and signal the system to run.
The drawing shows a representative layout, and a licensed contractor determines exactly what the installation involves in your house.

Severe Weather Events in Franklin County
Heat pump performance is tied directly to what the climate demands of it year after year. How often and how hard the weather pushes here shapes the load a system carries, which makes local weather history a practical input when sizing and installing equipment for this area.
