Heating in Illinois: what's different
Heating across Illinois depends on the climate (IECC climate zones 4–5). Heating is the main load in cold climates. Furnaces and boilers run for months, so ignition, venting, heat exchanger and carbon monoxide checks before winter are important.
In Illinois specifically: frozen pipes during furnace failures. Subzero cold snaps make a failed furnace an emergency. Humid summers: Humidity and heat waves strain undersized AC systems.
Illinois has no statewide HVAC license; cities such as Chicago license contractors and require permits locally. Common systems in Illinois: Gas furnace + central AC, Boilers and radiators, Ductless mini-splits, Basement equipment.
