A contractor quoting a boiler installation in Champaign County starts from what the local climate actually demands of the equipment, because sizing and sealing decisions that work in quieter areas can fall short here. 317 severe weather events were recorded in Champaign County, Illinois between 2015 and 2024. At that rate, severe weather is part of the normal operating environment, not an edge case, and a boiler spec that ignores it leaves the system working against conditions it was never fitted for. Contractors price and size for that load from the first visit.
Existing ductwork is what a contractor prices around when installing a boiler in Champaign County. Half the homes in Champaign County, Illinois were built in 1981 or earlier (2020-2024 ACS 5-year). Houses built in that era were laid out for the equipment of that era, and the runs, clearances, and connections inside them reflect those original choices. A new boiler puts different demands on what is already there, and whether the existing layout can meet them is the first thing a contractor has to establish before any other part of the job gets priced.
What Gets Installed With a New Boiler
The boiler itself sits in the basement or a utility room and is the unit a homeowner notices first when work is done. It heats water and sends it out through the house. A contractor mounts the boiler against a wall with clearance on all sides for safe operation and future service access.
Radiators or radiant floor manifolds sit at the rooms they serve, and supply and return pipes connect them back to the boiler. An expansion tank mounts near the boiler to absorb pressure changes in the water as it heats. A circulator pump, also near the boiler, pushes water through the loop. The thermostat goes on an interior wall away from drafts and direct sun.
The drawing shows a general layout of these components, and a licensed contractor determines exactly how they apply to this house.

Licensing and Legal Requirements in Champaign 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 Champaign County
