About Besco Air Inc.
Besco Air Inc. works from Northwest Highway in Norwood Park, close to the edge of the city and the northwest suburbs. The company says it was founded in 1986, and its service area stretches from Chicago out to Park Ridge, Des Plaines, Skokie, Northbrook, Arlington Heights, Palatine, Barrington and Buffalo Grove.
Besco handles heating and cooling repair, maintenance and replacement, and it installs Trane, Lennox and Mitsubishi equipment along with Aprilaire indoor air quality products. The website says the company is a designated Trane Comfort Specialist. Two policies stand out. First, Besco says all of its work is done by its own employees, with no subcontractors, which matters when you want accountability on a new system. Second, it provides a written warranty on its workmanship, on top of the manufacturer warranties on the equipment. It also offers free in-home estimates, flexible financing and 24/7 emergency service.
The reviews reflect that approach. One homeowner praised a salesperson named Bob McCarthy for detailed advice before and after the sale, and a four-person install crew led by Aldo Gil for careful work. Another has had a technician named Jim maintain their air conditioner for two years and describes every visit as professional and thorough. Mike, Luis, Angel and Giovanni also come up in reviews, which suggests a steady team.
The Google profile lists the business as open 24 hours. License numbers are not published on the pages we reviewed, so ask for them before work begins.
Who it suits: homeowners on the Northwest Side and in the northwest suburbs who want a Trane or Mitsubishi system installed by a company's own staff, with a written workmanship warranty. Who it suits less well: anyone looking for plumbing or electrical work alongside HVAC.
Before signing, ask how long the written workmanship warranty lasts, whether the install includes permits and haul-away, and which rebates apply to the equipment you choose.
