AHR Expo Preview: Coming to Chicago?

Jan. 9, 2024
The new year is here and the big show is just around the corner. Are you ready?


The 2024 Air Conditioning, Heating and Refrigeration Exposition (AHR Expo) returns to Chicago January 22-24. The show is the premiere event for the HVAC/R industry, and, due to its size and scope, attracts attendees from across a broad spectrum of the built environment—contractors, manufacturers, engineers, wholesalers, distributors—including a large contingent of plumbing and hydronic heating professionals.

There have been 75 AHR Expos since the launch of the event in 1930 in Philadelphia as a spin-off of The National Exposition of Power and Mechanical Engineering. Since its inception, the show has been produced by the International Exhibition Company (IEC).

In 1947, IEC brought in the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) as a show co-sponsor and in the early 1970s the Air-Conditioning, Heating and Refrigeration Institute (AHRI) joined the co-sponsorship. Both esteemed organizations continue this partnership, with ASHRAE co-locating its Annual Winter Meeting with AHR to this day.

The 2024 Expo is expected to attract more than 50,000 attendees, include more than 1,600 exhibitors from around the world and offer more than 370 speakers. Following are just a few of the more highly anticipated show offerings. For a full list of features, exhibitors, and education offerings, visit the AHR Expo site at

Tips for the Show

Plan your visit to get the most out of the experience. The show is simply too big to just wander around visiting random booths. Ask yourself what you hope to get out of the show and make some keyword searches on the web site. Download the AHR Expo app from the Google Play Store or by visiting Build your show schedule (and be sure to book time to eat and relax). The app will synch automatically with your MyShow planner account on the AHR Expo online directory.

If something you see or hear at a booth catches your interest, get your badge scanned. This will usually get you on the company’s email list for updates on their latest product and service offerings. You can always unsubscribe at any time.

Bring snacks. Food at convention centers is notoriously expensive. Lines are often long and if you have a busy schedule getting a bite to eat may be too time-consuming. Remember to stay hydrated.

Wear comfortable shoes—a million square feet is a lot of space to cover.

If you’re feeling sick, stay at your hotel. If you think you might be sick social distance and wear a mask. However you may be feeling wash your hands frequently and thoroughly. The pandemic may be over, but the endemic is here to stay and 50,000 people in one building means someone is going to catch something.

Safe travels, and we’ll see you at the show.
