AHR Expo 2027 in Chicago: where the HVACR industry meets

Every January the AHR Expo turns Chicago into the global capital of HVACR. Manufacturers, engineers, contractors and facility managers from more than 100 countries come together to see what's next in heating, ventilation, air conditioning, refrigeration and plumbing — from next-generation refrigerants and heat pumps to smart building controls and indoor air quality systems. Across three days on the McCormick Place show floor, more than 1,900 exhibitors display their newest products and technologies, while free industry seminars, panel discussions, for-credit courses and live podcast sessions give attendees practical takeaways they can put to work right away. The ASHRAE Winter Conference runs concurrently, adding 100+ technical sessions for those who want a deeper dive. Whether you're specifying equipment for a major project, sourcing components for distribution, or tracking where the industry is heading on decarbonization and refrigerant transitions, the AHR Expo is where the HVACR community meets face to face.
