Sizing a heat pump for Wabash County means accounting for what the local climate actually demands, and the local record gives a contractor firm ground to stand on. 75 severe weather events were recorded in Wabash County, Illinois between 2015 and 2024. At that rate, severe weather is a recurring presence but not a constant one, which means installation decisions here turn on long-run load calculations and equipment placement more than on storm exposure alone. A contractor who prices the job correctly is pricing for the climate this area carries year to year, not for a worst-case season that rarely arrives. Refrigerant line routing, insulation at penetrations, and outdoor unit siting all respond to that kind of load.
Ductwork sized and routed for a furnace does not automatically suit a heat pump, and in Wabash County the age of the housing stock means a contractor runs into that mismatch often. Half the homes in Wabash County, Illinois were built in 1970 or earlier (2020-2024 ACS 5-year). A system built around a furnace moves less air and at higher temperatures than a heat pump does, so ducts that worked fine for decades may need to be rebalanced, rerouted, or replaced before the new unit can do its job. The electrical panel is a separate question, but the ductwork is usually what drives the scope.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a pad or bracket outside the house, and it holds the compressor and the outdoor coil. Inside, the air handler sits in a mechanical room, closet, or attic and moves conditioned air through the home. These two units are the core of what a contractor puts in.
A refrigerant line set runs between the outdoor unit and the air handler, connecting the two through an exterior wall. A thermostat goes on an interior wall and gives the homeowner control over the system. A condensate drain line carries moisture from the air handler to a floor drain or outdoors.
The drawing shows a general layout of these components, and a licensed contractor determines exactly how each one is positioned and connected in your house.

Licensing and Legal Requirements in Wabash County, Illinois
Illinois leaves HVAC licensing to the municipality: state law lets the corporate authorities of each city or village examine, license and regulate heating, air conditioning and refrigeration contractors, and caps the licence fee they may charge at $50 — so who licenses you depends on the town you work in.
