The world’s largest HVACR marketplace — 1,800+ exhibitors and 50,000+ attendees. Every major cooling equipment manufacturer shows up here.

This is where you walk the floor and compare cooling hardware side by side: direct-to-chip liquid cooling systems, rear-door heat exchangers, precision air handlers, CDUs, and everything in between. If you’re specifying or evaluating cooling equipment, AHR gives you more options in one venue than months of vendor meetings.
