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.

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.
HVAC Education — What Chicago Homeowners Should Know
How Your HVAC System Works Together
A complete HVAC system includes a heating source (furnace or boiler), a cooling source (air conditioner or heat pump), air distribution (ductwork or hydronic piping), and controls (thermostat). Each component must be properly sized and matched to work efficiently. D's Air installs and services all components as a complete system.
Chicago's Climate Demands
Chicago experiences some of the most extreme temperature swings in the country — from -20°F wind chills in winter to 100°F heat indexes in summer. Your HVAC equipment must be sized and installed to handle both extremes reliably. D's Air has served Chicago since 2009 and understands what local homes require.
The Importance of Annual Maintenance
Annual tune-ups extend equipment life, maintain efficiency, and catch problems before they become failures. A well-maintained furnace lasts 20+ years. A neglected one may fail at 12–15 years. D's Air offers annual maintenance plans for both heating and cooling equipment.
Energy Efficiency and Savings
Upgrading from a 10 SEER AC to a 16 SEER unit cuts cooling costs by roughly 37%. Upgrading from an 80% AFUE furnace to a 96% AFUE unit cuts heating costs by about 17%. Over 10–15 years, these savings typically exceed the cost difference between standard and high-efficiency equipment.
