A contractor quoting a heat pump installation in Christian County starts with what the house actually demands, not with a weather story. 142 severe weather events were recorded in Christian County, Illinois between 2015 and 2024. At that rate, severe weather is a real but occasional presence, not a condition that grinds equipment down season after season. A system that underperforms here was more likely undersized at install or set up without attention to the local load profile. That is why a contractor checks Manual J calculations and the quality of the existing ductwork before recommending equipment, not after.
Ductwork laid down for a furnace carries air in one direction at one volume, and a heat pump asks something different of it. Half the homes in Christian County, Illinois were built in 1963 or earlier (2020-2024 ACS 5-year). That puts the existing duct system, not the outdoor unit, at the center of what a contractor has to evaluate before a heat pump job can be priced. Electrical service is the second question: a panel installed for the loads of that era often needs assessment before a new unit can be connected. The equipment gets chosen after those answers are in hand.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners recognize first. It sits outside the house on a pad or wall bracket and holds the compressor and the main coil. Inside, an air handler mounts in a mechanical room, basement, or utility closet and moves conditioned air through the home's supply system.
A refrigerant line set runs between the two units, connecting outdoor to indoor through a small penetration in the wall. A thermostat goes on an interior wall where it reads the living space and tells the system when to run.
The drawing shows a typical layout, and a licensed contractor determines what fits the specifics of your house.

Licensing and Legal Requirements in Christian 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.
Severe Weather Events in Christian County, Year by Year
Heat pump performance is tied directly to what the weather demands of it, and those demands vary by place. How hard the equipment works over its life is a local question, and the pattern of severe weather here is part of that answer.
