D's Air & Heating has been serving Addison, IL homeowners and commercial properties since 2009. We're a family-owned team of EPA certified technicians — not a call center dispatching strangers — and we carry full authorization from Lennox, Carrier, and Green to sell and service the equipment we install. When your furnace goes out in January or your AC quits in August, you need someone who shows up, knows what they're doing, and stands behind the work. That's what we've built our reputation on, one referral at a time.

 

Our 4.8-star Google rating reflects the relationships we've built across the Chicago area and the suburbs we serve. Addison is part of that footprint, and we bring the same standards here that our long-term customers in the city have come to expect.

Why Addison Homeowners Choose an Authorized Lennox Dealer


Choosing an authorized Lennox dealer isn't just about brand preference — it affects your warranty coverage, your equipment eligibility, and the quality of the installation itself. Lennox requires authorized dealers to meet ongoing training and certification standards. When we install a Lennox system in your Addison home, you get the full manufacturer warranty, properly registered and in your name.

 

Beyond the credentials, we're a local business that depends on word of mouth. We don't have a national franchise to fall back on if a job goes sideways — our name is on every call we make. That accountability shows up in how we work.
