A contractor quoting a heat pump installation in Edwards County works through the same set of local variables before any equipment gets specified: the heat and cooling load of the house, the condition of the existing ductwork, and whether the proposed location suits the unit. 71 severe weather events were recorded in Edwards County, Illinois between 2015 and 2024. At that rate, severe weather is an occasional presence rather than a standing condition, which means the installation decisions that determine how a system performs here are driven by the building itself rather than by a need to design around a punishing outdoor environment. A poorly sized or poorly sited unit will underperform regardless of what the sky does.
Ductwork laid out for a furnace and central air setup carries air in a particular pattern, at particular volumes, and a heat pump running the same routes does not always agree with what it finds. Half the homes in Edwards County, Illinois were built in 1970 or earlier (2020-2024 ACS 5-year). A contractor installing a heat pump here opens that question before anything else: whether the existing runs, returns, and register sizing will move air the way the new system needs, or whether corrections are part of the job. The electrical service is a separate check. Both have to be settled before the equipment is ordered.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, set on a pad beside the house. It holds the compressor and the outdoor coil, and it is where heat is pulled from or pushed to depending on the season. Inside, the air handler mounts in a utility space, attic, or basement and moves conditioned air through the home.
A refrigerant line set runs between the two units, carrying refrigerant through insulated copper tubing that passes through the building envelope. A thermostat goes on an interior wall and gives the homeowner control over the system. Some installations also include a supplemental electric resistance element inside the air handler for the coldest days.
The drawing shows a typical layout, and a licensed contractor determines exactly how each component fits the specifics of your house.

Licensing Rules for Edwards 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 Edwards County, Year by Year
Heat pump performance is tied directly to what the outdoor air does, and what it does here is shaped by local weather patterns that push equipment harder in some years than others. A heat pump sized and installed for this county's actual climate load does a different job than one spec'd for somewhere else.
