A contractor quoting a heat pump install in Franklin County is not working against a punishing weather history. 47 severe weather events were recorded in Franklin County, Indiana between 2015 and 2024. At that rate, severe weather is an event here rather than a standing condition, which means the variables that actually shape a good install are local load calculation, equipment sizing for the house's envelope, and the quality of the refrigerant and electrical work. A system that fails in this county almost always traces back to those factors. The install question is technical, not meteorological.
Ductwork laid down for a furnace and central air setup carries air at a pressure and volume that suits that system, not the lower static pressure a heat pump moves air through. Half the homes in Franklin County, Indiana were built in 1981 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump installation in a house from that era has to pull registers, check trunk lines, and measure what the existing runs can actually handle before the equipment price means anything. Electrical service from the same period often predates the dedicated circuits a heat pump compressor and air handler each require. The unit itself gets selected after those constraints are known.
What a Heat Pump Installation Covers, Piece by Piece
The outdoor unit sits on a pad beside the house and holds the compressor and the coil that pull heat from outside air. The indoor air handler mounts inside, often in a utility room or closet, and moves conditioned air through the home. These two units are the core of what a contractor places and connects.
A refrigerant line set runs between the outdoor unit and the air handler, carrying refrigerant back and forth through insulated copper tubing. A condensate drain line runs from the air handler to a floor drain or outdoors, clearing the moisture the system pulls from indoor air. A thermostat goes on an interior wall and gives the homeowner control over the whole system.
The drawing shows a typical layout, and a licensed contractor determines what fits the conditions in your specific house.

Heating and cooling loads in Franklin County are shaped by what the weather actually does here, not by regional averages. A heat pump sized and installed for local conditions handles that workload differently than one spec'd without it.
