Record square footage at the AHR Expo -- 530,000 sq. ft. -- most likely resulted in record mileage walked by show attendees. But that's what you sign up for when you come to the AHR Exposition.
The total number of exhibitors reported by International Exposition Co. came in at 2,155. There are 37 more exhibitors at McCormick Place, which beats last year's Las Vegas event by 29,851 square feet.
We were there for the second day, and here are some of the people and products we encountered.
The AHR Expo continues through today.
