Chicago’s heating season drives indoor humidity below 20%, which dries skin and sinuses, cracks woodwork and makes a warm house feel cold. A whole-home Aprilaire humidifier restores comfortable 35–45% humidity automatically, while an Aprilaire air purifier captures dust, pollen and allergens the furnace filter misses.
Aprilaire 600 / 600M — bypass humidifier for most homes. Aprilaire 700 / 700M — fan-powered, up to 4,200 sq ft. Aprilaire 800 Steam — steam humidification for large or very dry homes.
Fall Specials 2026: $100 off the 600, $125 off the 700, $200 off the 800 Steam (with normal installation).
Aprilaire Model 3000 and Model 5000 media air cleaners install on your existing furnace and treat every room, every cycle. Ideal for allergies, pets and city dust.
Fall Specials 2026: $100 off the Model 3000, $150 off the Model 5000.
Our state-of-the-art air duct cleaning covers your entire single-family home with unlimited vents — supply and return ducts, registers and the main trunk lines — removing years of dust, pet hair and construction debris so your furnace and AC breathe easier and your air stays cleaner. Currently $125 off with our Fall 2026 coupon.
