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.
Chicago's Authorized Lennox Dealer Since 2009 — What You Should Know
D's Air & Heating — Authorized Lennox Dealer Since 2009
D's Air & Heating is an Authorized Local Chicago Lennox dealer since 2009. As an authorized dealer, we receive factory training on every Lennox product line, have direct access to Lennox technical support, and can register your equipment for the full Lennox manufacturer warranty. Not every HVAC company that sells Lennox equipment is an authorized dealer — authorization matters for warranty coverage and installation quality.
The Lennox Product Lineup
Lennox manufactures three residential product tiers: Merit Series (reliable, efficient entry-level equipment), Elite Series (enhanced efficiency and comfort features), and Dave Lennox Signature Collection (the highest efficiency and most advanced comfort technology available). D's Air installs and services all three tiers and can help you choose the right level for your home and budget.
Lennox Installation Standards
Lennox requires authorized dealers to follow specific installation procedures to maintain warranty coverage. This includes proper refrigerant charging by weight, matched system combinations (condenser + coil + air handler), correct thermostat wiring for communicating systems, and equipment registration within 30 days of installation. D's Air follows every Lennox installation requirement on every job.
Lennox Warranty Coverage
Lennox offers industry-leading warranty coverage when equipment is installed by an authorized dealer and registered within 30 days: 10-year limited warranty on parts for most equipment, 20-year limited warranty on heat exchangers, and 5-year limited warranty on compressors (extended to 10 years with registration). D's Air registers every Lennox installation for the full warranty.
Lennox iComfort Smart Controls
Lennox communicating systems use the iComfort S40 or M30 smart thermostat to coordinate furnace, air conditioner, and air handler operation for maximum efficiency and comfort. The thermostat monitors system performance, alerts you to maintenance needs, and can be controlled remotely via the Lennox app. D's Air configures and programs iComfort systems on every communicating Lennox installation.
