Chicago housing and HVAC
Bungalows and two-flats often have boilers with radiators or gas furnaces in basements. Many older units lack central air and use window units or mini-splits. High-rises use building-wide systems or fan coils.
Cold winters with subzero cold snaps and lake-effect snow, hot humid summers, and fast temperature swings near Lake Michigan.
Permits and seasonal timing in Chicago
The Chicago Department of Buildings issues permits and licenses HVAC contractors in the city, while suburbs like Evanston and Oak Park have their own requirements. Schedule boiler and furnace service in September or October, before the first cold snap, and AC service in spring. Contractors are busiest during January cold waves and July heat waves.
Boiler service
Older buildings need annual boiler service, radiator bleeding and safety checks.
Adding AC to older homes
Ductless mini-splits and high-velocity systems avoid opening plaster walls.
Frozen pipes
A failed furnace or boiler during a cold snap can quickly freeze pipes.
Lake-effect and wind
Wind off Lake Michigan increases heat loss, so air sealing and insulation make heating systems more effective.
