The Epicenter of Comfort: Venue, Time, and Cost

The ASHRAE AHR Expo consistently chooses North America’s largest and most accessible convention centers to accommodate its immense scale and global appeal. Chicago, with its central location and world-class facilities, is a frequent and favored host.

Chicago: A City Built for Big Events When the AHR Expo is in Chicago, it leverages the colossal capacity of one of the world’s premier convention venues:

• McCormick Place: Located at 2301 S King Dr, Chicago, IL 60616, USA, McCormick Place is the largest convention center in North America. Its sheer size and state-of-the-art facilities—including multiple exhibition halls (North, South, East/Lakeside Center, West), expansive meeting rooms, advanced technology infrastructure, and numerous dining options—make it the perfect host for an event of the AHR Expo’s magnitude. Its location just south of downtown Chicago also offers excellent accessibility via public transport, taxis, and ride-shares.

The Annual Industry Kick-Off: Time and Duration The ASHRAE AHR Expo is an annual event, strategically timed at the beginning of the year to allow professionals to gather, assess the latest innovations, and plan their strategies for the year ahead.

• When It Happens: The Expo typically takes place in late January or early February. For example, the 2024 AHR Expo was held in Chicago from January 22-24, 2024. The 2025 AHR Expo is scheduled for February 10-12, 2025 in Orlando, and the 2026 Expo will return to Chicago. So, the location rotates, but the time of year remains consistent.
• Duration: The exhibition hall is generally open for three intensive days, typically Monday through Wednesday. Show hours are usually from 10:00 AM to 6:00 PM on the first two days and 10:00 AM to 4:00 PM on the final day. These core exhibition hours are often complemented by educational sessions, professional development courses, and special events hosted by ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) concurrently, often starting a day or two before the Expo floor opens.

Cost of Admission: An Investment in Your Future The AHR Expo strives to be accessible to a wide range of industry professionals, with a generally reasonable registration fee structure.

• Attendees: For pre-registration, general attendee admission to the Expo floor is often free of charge if you register in advance (typically by a deadline in early January). On-site registration, however, usually incurs a fee, which can be around $30 – $50 USD. This allows attendees to access hundreds of exhibitors and see the latest products.
• Educational Sessions: While access to the exhibit floor is often free for early registrants, specialized educational seminars, ASHRAE Winter Conference sessions (which run concurrently with AHR Expo), and professional development courses typically have separate fees. These can range from $200 – $600+ USD depending on the number of sessions or full conference pass chosen.
• Exhibitors: The cost to exhibit varies significantly based on booth size, location, and amenities desired. It’s a substantial investment, reflecting the immense lead generation and brand exposure opportunities available at the largest event of its kind.

The accessible entry fee, especially for early registration, makes the AHR Expo an incredibly cost-effective way to gain unparalleled market insight and network with industry leaders.
