A contractor quoting a furnace install in Kane County has to account for what the equipment will be asked to carry here, not just what the house measures on a calm day. 298 severe weather events were recorded in Kane County, Illinois between 2015 and 2024. At that rate, severe weather is a standing condition rather than a rare interruption, and a system sized or sealed for milder operating conditions will be working against its own spec every heating season. Duct connections, heat exchanger fit, and combustion air supply all get specified against local load on a job done right.
Ductwork laid into a house built around the median year for this county was sized for the equipment and standards of that time, and a modern furnace draws air differently enough that a contractor has to assess what is already in the walls before anything else gets priced. Half the homes in Kane County, Illinois were built in 1985 or earlier (2020-2024 ACS 5-year). That gap between when the duct system was designed and what a new furnace will ask of it is where most installation decisions actually get made. A contractor who skips that assessment and quotes only the unit will often find the scope changes once work begins.
What Gets Installed With a New Furnace
The furnace itself sits in a utility space, basement, or closet and is the unit that generates heat. A heat exchanger inside it warms the air that moves through your home. The flue pipe runs from the furnace to an exterior wall or up through the roof, carrying combustion gases out.
The blower motor sits inside the furnace cabinet and pushes conditioned air into the supply side of your duct system. A new installation also includes the gas line connection at the furnace, the condensate drain if the unit is high-efficiency, and the thermostat wiring that tells the furnace when to fire.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific house and equipment configuration.

Licensing and Legal Requirements in Kane 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.
