Besco Air Inc. has been Chicago’s own heating and cooling contractor since 1986, growing from a single office into a family-owned company with locations in Chicago and Northbrook, IL. The company does all of its installation and repair work with its own staff rather than subcontracting, and many of its technicians have logged more than a decade on the job.

As a Trane Comfort Specialist, Besco Air earned a full slate of manufacturer recognition in 2025, including the Highest Growth Award for ranking #1 in Trane growth in its market, the High Efficiency Award, the Mitsubishi Award, the Wells Fargo Financing Award, and the Distinguished Dealer Award. That builds on an Angie’s List Super Service Award the company picked up back in 2019 and its A+ accreditation with the Better Business Bureau.

Homeowners across the northern suburbs count on Besco Air for more than routine repairs. The company’s NATE-certified technicians run fully stocked service vehicles with mobile dispatching, hold a three-hour appointment window standard, and back every job with 24/7 emergency coverage. Free in-home estimates and 0% APR financing for 18 months on qualifying systems make it easier to plan a system replacement rather than nurse an aging unit through another season.

Beyond equipment repair, Besco Air carries and installs Trane, Lennox, Mitsubishi, and Aprilaire products, and its service list stretches into moisture control and boiler work alongside its core heating and air conditioning offerings. That range lets the same crew that tunes up a furnace in the fall also handle indoor air quality upgrades or a boiler swap without bringing in a second contractor.

Beyond the city of Chicago itself, Besco Air’s service area stretches through Evanston, Highland Park, Lincoln Park, Logan Square, Lakeview, Wilmette, Winnetka, and Schaumburg, among other North Shore and northwest suburb communities. Whatever the neighborhood, the company’s stated approach is the same: be large enough to handle serious HVAC challenges, but small enough that customers still get treated like neighbors.
