AHR Expo is the HVAC industry’s essential opportunity to see everyone and everything in HVAC. The International Air-Conditioning, Heating, Refrigerating Exposition (AHR Expo), which started in 1930 as a heating and ventilation show, has grown into the largest event in the world exclusively focused on the HVACR industry. The 2026 Show will be held in Las Vegas, hosting industry professionals from all across the United States and worldwide. If you’re a contractor, engineer, architect, OEM, distributor, utility operator, facility manager, or other HVACR professional – the AHR Expo is designed for you. The Show is co-sponsored by ASHRAE and AHRI, and is held concurrently with ASHRAE’s Winter Conference.
