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.
