About indoor air quality
Chicago Air Is Too Dry in Winter and Too Damp in Summer
When frigid outdoor air is heated indoors, its relative humidity drops sharply, and many Chicago homes sit well below 30% humidity in January. That’s the static shocks, dry skin, cracked wood floors and scratchy throats. In July the problem flips to sticky, damp air.
A whole-house humidifier on the furnace adds moisture through the ductwork all winter, and a whole-house dehumidifier pulls it out in summer, especially in basements. Filtration and air purifiers deal with dust, pollen and smoke.
A smart thermostat ties it together, with schedules and humidity control, and the right staging for heat pumps and two-stage furnaces.

Practical guide
Indoor Air Quality in a Chicago Home
What humidity should my home be in winter?
Roughly 30 to 40% is comfortable for most homes, but on very cold days a lower setting keeps condensation and frost off windows. Many humidifier controls adjust automatically to the outdoor temperature for exactly that reason.
Radiator-heated homes
Homes with boilers have no ductwork, so a furnace-mounted humidifier isn’t an option. Room humidifiers or a ducted system added with high-velocity AC are the usual answers.
Smart thermostat installs
Many smart thermostats need a common (C) wire for steady power, which older Chicago thermostat wiring often lacks. A technician can add one or install an adapter, and set the thermostat up correctly for boilers, heat pumps and multi-stage systems.

Air quality FAQ
Indoor Air Quality Questions From Chicago Homeowners
Short answers to what Chicago homeowners ask most before they call.
(312) 924-7223If your home has forced-air heat and you notice static, dry skin, nosebleeds or gaps in wood floors in winter, a whole-house humidifier usually helps.
Yes, if humidity is set too high on very cold days. Controls with an outdoor sensor lower the setting automatically as temperatures drop.
For households with allergies, pets or smoke from nearby wildfires, a whole-house air cleaner captures much more than a standard filter and covers every room the ducts reach.
Yes. Many smart thermostats work with boilers; the technician checks the wiring and compatibility first.
