Lennox Steam Humidifier
High-output steam humidifier for precise humidity control
The Lennox Steam Humidifier generates steam to add moisture to your home's air independently of the furnace — so it works even when the heating system isn't running. It's the best choice for tight, energy-efficient homes where bypass humidifiers can't keep up.

- Higher output than bypass models
- Ideal for tight, energy-efficient homes

- Best choice for homes with very dry air problems
Lennox Whole-Home Dehumidifier
Whole-home dehumidifier for basements and humid climates
The Lennox Whole-Home Dehumidifier removes excess moisture from your entire home — not just one room. It integrates with your existing HVAC ductwork and is especially effective for Chicago's humid summers and damp basements where portable dehumidifiers can't keep up.
- Removes up to 90 pints of moisture per day
- Reduces mold, mildew, and musty odors
- Integrates with existing HVAC ductwork
- Automatic dehumidistat control

Why Choose D's Air & Heating, Inc.?
Chicago's trusted HVAC company since 2009 — licensed, insured, and committed to honest workmanship on every job.
Experience Since 2009
D's Air & Heating has served Chicago homeowners and businesses since 2009. Over 15 years of local HVAC experience means we've seen every type of system, every Chicago building configuration, and every challenge the city's climate presents.
Manufacturer-Trained Technicians
Our technicians receive ongoing manufacturer training and certification. We install Lennox, Goodman, Amana, Daikin, Sinclair, Weil-McLain, Peerless, and other leading brands — and we know each system inside and out.
Licensed, Insured & Permitted
D's Air & Heating holds Illinois HVAC License #2183457 and carries full liability insurance. We pull City of Chicago permits on every installation — protecting you legally and ensuring the work meets code.
Honest Recommendations
We tell you what you need — not what generates the highest invoice. If your system can be repaired cost-effectively, we'll say so. If replacement makes more sense, we'll explain exactly why. No pressure, no upselling.
Local Chicago Expertise
We know Chicago's housing stock — two-flats, greystones, bungalows, vintage buildings with steam heat, modern construction with forced air. We size and install equipment for the specific demands of Chicago homes and Chicago winters.
Long-Term Customer Support
Our relationship doesn't end at installation. We register your equipment for warranty, remain available for follow-up questions, and provide ongoing maintenance to keep your system running at peak efficiency for years.
Indoor Air Quality in Chicago — What Homeowners Should Know
Why Indoor Air Quality Matters
The EPA estimates that indoor air is 2–5 times more polluted than outdoor air. Chicago homes — especially older buildings with limited ventilation — accumulate dust, allergens, volatile organic compounds (VOCs), combustion byproducts, and biological contaminants. Modern HVAC systems can address all of these with the right equipment.
Air Filtration — MERV Ratings Explained
MERV (Minimum Efficiency Reporting Value) rates how effectively a filter captures particles. Standard 1-inch filters are MERV 1–4 and capture only large particles. MERV 8 filters capture most dust and pollen. MERV 13 filters capture fine particles including bacteria and smoke. High-efficiency media filters (MERV 13–16) provide hospital-grade filtration without restricting airflow.
Humidity Control
Chicago winters are extremely dry — indoor relative humidity can drop below 20% when it's cold outside. Low humidity causes dry skin, static electricity, wood shrinkage, and increased susceptibility to respiratory infections. A whole-home humidifier connected to your HVAC system maintains 35–45% relative humidity automatically. In summer, a whole-home dehumidifier prevents mold growth and improves comfort.
UV Air Purification
UV-C light systems installed in the air handler kill bacteria, viruses, and mold spores as air passes through. Lennox PureAir and similar systems combine UV-C with activated carbon filtration to address both biological contaminants and chemical pollutants (VOCs, odors). These systems are particularly valuable for households with allergy or asthma sufferers.
