What should indoor humidity be in Chicago homes?
Chicago-area homes should hold 30–40% relative humidity in winter and 40–50% in summer. Static shocks, cracked wood floors, and irritated sinuses signal winter air below 30%; sticky air above 55–60% in summer feeds dust mites, odors, and biological growth.
Whole-Home Humidity Control, Set and Forget
Whole-home humidifiers and dehumidifiers integrated with your HVAC system hold the healthy range automatically year-round — protecting your family’s comfort, your wood floors, and the home itself. A room-by-room humidity measurement shows whether your levels are where they should be.
