A contractor quoting a heat pump installation in Jasper County has to work out what the system will actually be asked to do before settling on equipment size or configuration. 79 severe weather events were recorded in Jasper County, Indiana between 2015 and 2024. At that rate, severe weather is a recurring feature of life here, steady enough that a contractor accounts for it, but not so constant that it overrides every other sizing variable. Soil conditions, duct layout, and how well the building envelope holds temperature all shape the final spec at least as much. A heat pump installed without those local variables factored in will be undersized or oversized regardless of how many storm seasons it faces.
Ductwork laid down for a furnace and central air setup carries different dimensions, different return configurations, and different static pressure assumptions than a heat pump system runs on. Half the homes in Jasper County, Indiana were built in 1985 or earlier (2020-2024 ACS 5-year). A contractor quoting a heat pump here sizes the new unit against what the existing duct system can actually move, not against what the house looks like on paper. Where the ductwork falls short, the electrical service gets checked next, since older panels were wired for the loads of their time. Those two assessments shape the quote before the equipment is even selected.
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 core work of moving heat. Inside, an air handler is mounted in a utility space, basement, or attic and distributes conditioned air through the home. These two units are the main hardware a contractor sets in place.
A refrigerant line set connects the outdoor and indoor units, running through the wall or crawlspace to carry refrigerant between them. A thermostat goes on an interior wall where it reads the air temperature and signals the system to run. A condensate drain line also runs from the air handler to carry away any moisture the unit pulls from the air.
The drawing shows a general layout of these components, and a licensed contractor determines exactly how each one 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 here needs to handle year after year. How hard a system works, and how well it holds up, is a local question.
