Air Conditioning in Illinois: what's different
Air Conditioning across Illinois depends on the climate (IECC climate zones 4–5). Cooling seasons are shorter in cold climates, but summer heat waves still bring urgent AC calls, often for systems that sat unused all winter. Spring start-up checks catch failed capacitors, low refrigerant and blocked drains.
In Illinois specifically: 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.
ComEd serves northern Illinois and Ameren Illinois serves much of the rest. Nicor Gas, Peoples Gas and Ameren supply natural gas.
