Indianapolis pulls in a solid mix of trade and industry conferences across 2026, spanning construction, fleet, HVAC, and contractor networks.
This page covers ten events worth tracking if you're building a presence in the Midwest or targeting buyers who cluster around Indianapolis each spring. Work Truck Week brings commercial fleet and upfitting professionals to the Indiana Convention Center in March, making it one of the earlier high-traffic stops of the year. The AD PHCP Spring Network Meeting in April draws HVAC, plumbing, and industrial distribution professionals into focused dealer and supplier conversations. Some events on this list are regional, some national, and one runs virtually. That range matters if you're managing a lean events calendar and need to decide which in-person commitments are worth the budget. Each listing includes dates, location, and context to help you plan around the conferences that actually fit your pipeline.
