Gartner HVAC has been family-owned and operated since 1985, serving homeowners and businesses from our shop at 4550 Oakton Street in Skokie. For more than four decades, we’ve built our name the old-fashioned way: showing up, doing the job right, and treating every home like it belongs to one of our neighbors, because it usually does.
Today Gartner is led by Darren Gartner. As a family-owned company, we have a double commitment: top performance on every installation and repair, and the kind of personal service a big franchise can’t match. Customers tell us they appreciate that the owner is involved, that our crews explain things in plain language, and that we leave their homes cleaner than we found them.
Our Story
CONFIRM: Family history. Ask Darren for 4–6 sentences: who founded the business and when, how Darren came into it, any family members working in the business today, and why the shop is on Oakton Street.
What We Stand For
- Dependability: we show up when we say we will, and we answer emergencies 24 hours a day
- Honesty: you get clear options and a clear price before any work starts, and we’ll tell you when a repair makes more sense than a replacement
- Craftsmanship: factory-trained installation to Bryant standards, and careful repairs on every make and model
- Respect for your home: shoe covers, drop cloths, and a clean workspace
Factory Authorized Bryant Dealer
Gartner is a Factory Authorized Bryant Dealer and has earned Bryant’s Circle of Champions award three years in a row. Bryant reserves that recognition for dealers who meet its standards for customer satisfaction and quality. It means our installations are done the way the manufacturer intends, with genuine parts and full warranty support.
