According to figures released by the International Exposition Co., which manages the annual event, there were 36,891 visitors and 20,782 exhibitor employees at this year's event. That was about 2,000 less than the all-time attendance record, which was more than 59,000. That record was set at the 2003 AHR Expo, which was also held in Chicago.
However, this year's Expo did set records for exhibitors (1,981), square feet of exhibits (411,175) and international exhibitors (400).
"We are delighted with this year's record-breaking event, as it reflects the growth of various industry segments within the AHR Expo and our ongoing efforts to add several show enhancements," Clay Stevens, president of the International Exposition Co., said.
Many exhibitors were also happy.
"This is our first time back since the 1990s and we are impressed with the traffic," said Terry Hoffman, director of marketing at Johnson Controls. "It proves that even when trade shows are declining, the AHR Expo has been sustainable."
"Our experience has been fantastic," Hirsch said. "We will absolutely be back."
As always, the show offered almost too many products to see in the three days the exhibit floor was open. But Snips managed to see most of the products important to HVAC and sheet metal contractors (or so we hope). Here's a list of some of the thousands of products on display.
