A heat pump going in here is sized against this area's actual heating and cooling demands, not against a weather record that strains equipment season after season. 60 severe weather events were recorded in Pope County, Illinois between 2015 and 2024. At that rate, severe weather is an occasional event in Pope County, not a standing condition every system has been grinding through. A contractor quoting an installation focuses on duct configuration, refrigerant line runs, and whether the unit is matched to the structure, because those variables drive long-term performance far more than weather load does here.
Ductwork designed for a furnace and central air setup handles air differently than a heat pump needs it to, and in a house old enough to have had that original layout in place for a long time, a contractor installing a heat pump has to assess whether the existing runs, returns, and sizing will actually carry the new system before anything else can be priced accurately. Half the homes in Pope County, Illinois were built in 1986 or earlier (2020-2024 ACS 5-year). That vintage of construction means the ductwork a contractor finds is unlikely to have been designed with heat pump airflow in mind, and whether it can be adapted or has to be replaced is what drives the real scope of the job.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners notice first. It sits on a pad outside the house and holds the compressor and the main coil, which do the work of moving heat between the refrigerant and the outside air. Inside, the air handler mounts in a utility space, basement, or closet and pushes conditioned air through the home.
A refrigerant line set runs between the two units, carrying refrigerant back and forth through insulated copper tubing. The thermostat goes on an interior wall and gives the homeowner control over the whole system. Some installations also include a supplemental electric resistance strip inside the air handler for the coldest days.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines exactly how each piece fits into your particular house.

Licensing Rules for Pope 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.
