Sizing a heat pump for Macoupin County starts with what the area actually asks of the equipment. 89 severe weather events were recorded in Macoupin County, Illinois between 2015 and 2024. At roughly the midpoint of counties nationwide, that record puts severe weather in the background of a heat pump install rather than at the center of it. A contractor here is working out duct layout, load calculations, and equipment capacity against a climate that is real but not extreme. The installation details that determine long-run performance are the ones that always matter: proper sizing, refrigerant charge, and air sealing.
Ductwork and electrical service were put into these houses for the systems that existed when the houses were built. Half the homes in Macoupin County, Illinois were built in 1966 or earlier (2020-2024 ACS 5-year). A heat pump draws more power than what most of that original wiring was sized to carry, which means the panel gets opened and assessed before a contractor can price the equipment or schedule the install. If the service capacity is short, that work comes first. The unit itself follows.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece most homeowners notice first. It sits on a pad beside the house and holds the compressor and the outdoor coil, which together do the core work of moving heat between inside and outside. 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 the refrigerant that links the outdoor and indoor sides into one system. The thermostat goes on an interior wall and gives the homeowner control over when and how the system runs. A disconnect box mounts near the outdoor unit as a local shutoff point for the equipment.
The drawing shows a typical layout, and a licensed contractor determines exactly how each component is positioned and connected in your specific home.

Licensing Rules for HVAC Work in Macoupin 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 Macoupin County
