HVAC professionals working on the West Coast have nine conferences worth tracking in 2026, spanning dealer meetings, indoor air quality research, and decarbonization policy.
This page covers events from Bellevue to San Diego, selected because they draw the contractors, engineers, and facility managers most active in Western markets. The ASHRAE Building Decarbonization Conference in Seattle this September sits at the center of the region's push toward electrification and building performance standards. Earlier in the year, the Women in ASHRAE Leadership Symposium in Los Angeles brings together a smaller, focused group of decision-makers often overlooked by broader trade show circuits. For operators building pipeline on the West Coast, the mix here reflects real buying cycles. Several events cluster in Southern California through June, which makes back-to-back attendance practical without cross-country travel.
