Ahr Expo 2024 Chicago Tickets. We are looking forward to exhibiting our innovative hvacr solutions to the expected 50,000+ attendees from 112 countries. Advance travel planning and early visa application are important since visa applications are subject to a greater degree of scrutiny than in the past.

As an international attendee or exhibitor, it may be necessary for you to receive an official invitation to obtain your travel visa. More than 1,800 exhibits are planned, and attendance is expected to be healthy.
