Sizing a heat pump for Warrick County means working from what the climate actually asks of a system, not from a catalog default. 108 severe weather events were recorded in Warrick County, Indiana between 2015 and 2024. At that rate, severe weather is part of the normal operating environment every system here runs against, and a contractor who ignores it when selecting equipment capacity and specifying the install will produce a system that fits the catalog and not the county. Refrigerant line lengths, mounting locations, and electrical specs all get set at installation, and those decisions carry the full load of years of local weather from that point forward.
Ductwork sized and routed for a different era of equipment shapes what a heat pump installation actually involves here. Half the homes in Warrick County, Indiana were built in 1986 or earlier (2020-2024 ACS 5-year). That vintage of construction was built around systems whose airflow demands differ from what a heat pump requires, which means a contractor has to assess what the existing ducts can carry before the equipment choice means anything. Electrical service is the second variable: the panel that served the original system may or may not support what a heat pump draws. Both get evaluated on site, and both can change the scope of the job.
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, the air handler mounts in a utility space, basement, or closet and pushes conditioned air through the home. Together these two units 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 small chase or wall penetration. A thermostat goes on an interior wall where it reads the living space and signals both units to run or stop. Each of these pieces is part of what a contractor installs when the system goes in.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.

Weather in this part of Indiana puts real demands on heating and cooling equipment, and those demands shape what a heat pump needs to handle over its working life. Sizing and installation decisions that ignore local conditions cost the homeowner more down the road.
