A heat pump going wrong in DeKalb County is most likely going wrong for reasons that have nothing to do with storm load. 66 severe weather events were recorded in DeKalb County, Indiana between 2015 and 2024. At that rate, severe weather is an event here, not a standing condition, and a contractor sizing or installing a new system is working around a relatively mild cumulative load. What drives failure and what drives a careful install quote here are the same things they are everywhere else in low-exposure areas: equipment age, refrigerant charge, duct layout, and whether the original unit was sized to the house rather than to a price point.
Ductwork laid for a furnace and central air setup carries assumptions about airflow, return sizing, and static pressure that heat pump systems do not share. Half the homes in DeKalb County, Indiana were built in 1975 or earlier (2020-2024 ACS 5-year). A contractor sizing a heat pump here has to assess whether what is already in the walls and ceilings will move conditioned air the way the new unit expects, and whether the electrical service will carry the load. Those two questions are answered by what is actually in the house, and the answers shape the quote before the equipment selection does.
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 into the home. Together these two units are what a contractor brings in and sets in place.
A refrigerant line set runs between the two units, connecting them through a small penetration in the wall. A thermostat goes on an interior wall where it reads the home's temperature and signals the system to run. Some installations also include a supplemental electric heat strip inside the air handler for the coldest stretches.
The drawing shows the typical layout of these components, and a licensed contractor determines exactly how each one applies to your house.

Heating and cooling loads here are shaped by what the weather actually does, and heat pump sizing and selection follow from that reality. A system chosen for this county's conditions handles the work asked of it; one chosen generically may not.
