Winter 2026 brings a focused stretch of HVAC conferences worth paying attention to, with six events running from late January through early February across the U.S. This page covers the ones most relevant to contractors, distributors, and industry professionals planning their Q1 calendar.
The ASHRAE Winter Conference in Las Vegas anchors the stretch, running January 31 through February 4 and overlapping directly with the AHR Expo at the same location. That back-to-back setup means one trip can cover both. Beyond Las Vegas, the list includes regional events like the PHCC San Diego Trades Expo and manufacturer-specific gatherings like the Trane-American Standard Dealer Meeting in Bellevue. If you're timing business development activity, scoping out new supplier relationships, or just trying to stay current on codes and standards, this window is one of the more efficient on the HVAC calendar.
