Furnace Repair & Installation in Skokie & the North Shore

When Your Furnace Stops, We Start

In a Chicago-area winter, a furnace isn’t a convenience. It’s what keeps your family safe and your pipes from freezing. Gartner HVAC has been repairing and installing furnaces in Skokie and the surrounding suburbs since 1985. Whether your furnace won’t ignite, is blowing cold air, keeps shutting off, or is simply getting old, our technicians find the real cause and give you honest options.

We work on every major brand, and we’re a Factory Authorized Bryant Dealer for new installations. That means factory training, genuine parts, and installation done the way the manufacturer intends.

New Furnace Installation & Replacement

When a repair no longer makes sense, Gartner sizes a new furnace to your home, not just to the old unit’s label. We look at square footage, insulation, windows, ductwork and how your family uses each room. Then we explain your choices: standard, high-efficiency, two-stage and variable-speed Bryant furnaces. Every installation includes proper venting, gas connections, condensate drainage, thermostat setup and a full safety test.

Signs It’s Time to Replace Your Furnace

• The furnace is 15–20 years old or older
• Repairs are getting more frequent and more expensive
• Heating bills keep climbing
• Some rooms are always too cold
• The heat exchanger is cracked (a safety issue)
