The list spans technical education, trade floor networking, and contractor business, so it works whether you're planning around product launches or hiring cycles. The AHR Expo Las Vegas 2026 anchors the year in early February, running alongside the ASHRAE Winter Conference at the same time in the same city. That overlap makes the first week of February a concentrated window for equipment manufacturers, contractors, and engineers to cover serious ground without multiple trips. Later in the year, events like ACCA Conference & Expo add a contractor-focused angle. If you're building a conference calendar around HVAC pipeline, this page gives you dates, locations, and enough context to decide which events are actually worth the trip.
