Chicago, USA · North America · Jan 25-27, 2027 · Free
AHR Expo is the HVACR industry's largest annual trade show, pairing a show floor of more than 1,900 manufacturers and suppliers with a free education program covering decarbonization, refrigerants, and building automation. It draws engineers, contractors, facility managers, and distributors who specify or buy HVAC and building-systems equipment, so energy-efficiency sellers with a hardware or controls product have buyers here. The 2027 edition runs at McCormick Place in Chicago.
- Who’s there
- Organizer figures describe engineers, architects, facility managers, contractors, wholesalers, distributors, manufacturer's representatives, OEMs, and design/build professionals across residential, commercial, industrial, and institutional HVACR markets, plus 8,000 international visitors from more than 100 countries and 500-plus international exhibitors among 1,900-plus manufacturers and suppliers exhibiting. No seniority percentage breakdown or total attendee headcount is published on the official site.
- Go if
- You sell a physical HVAC, refrigerant, or building-automation product. The show runs a decarbonization track, a large facility-manager and contractor buyer floor, and a free advance badge that makes the trip cost travel-only.
- Skip if
- You have no hardware, controls, or engineering-services product for buildings, such as a carbon-market trader or pure ESG reporting software. This is an equipment trade show, not a sustainability strategy conference.
- Scale
- The organizer publishes 1,900-plus exhibiting manufacturers and suppliers, 500-plus international exhibitors, and 8,000 international visitors from more than 100 countries. The homepage also shows 50,000 attendees and 350 speakers, without saying which edition.
- Tickets
- Advance attendee badge registration is free through January 23, 2027. After that date online registrations cost $30, and any attendee badge taken out onsite also costs $30; onsite exhibitor badges cost $10. All prices are in USD; VAT or tax status is not stated. The AHR Education Program, covering industry seminars, panel discussions, rapid-fire new product presentations, for-credit courses, and live podcasts, is free with a show badge. ASHRAE Learning Institute sessions and the concurrent ASHRAE Winter Conference are not included and require separate paid registration.
- Access & notes
- Register by January 23, 2027 to get in free; badges bought later or picked up onsite cost $30. Show hours are 10am to 6pm on January 25 and 26 and 10am to 4pm on January 27. The co-located ASHRAE Winter Conference is a separate paid event, so budget for it if the technical program matters.
