The NFL held the Super Bowl in Minneapolis recently, and 67,612 people were in attendance. Of course, that came in second to the HVACR Super Bowl, otherwise known as the AHR Expo, which saw a total attendance of more than 72,000.
Total attendance was just one of many records broken by the AHR Expo in 2018. It also set the highs in number of exhibitors, square feet of exhibit space, registered visitors, total visitor attendance, and countries represented.
