This page covers eight events worth knowing about, selected because they span a useful range of formats and audiences, from single-day regional expos to multi-day national conventions. The MCAA Annual Convention in Phoenix runs five days and draws mechanical contractors from across the country, making it one of the heavier networking commitments on this list. On the smaller end, events like the Illinois PHCC Expo and Educational Day offer a lower time investment with a tighter regional focus. If you're trying to map out where to show up this spring, whether to generate leads, meet subcontractors, or stay visible in a specific market, the dates here are close enough together that a few of them can be planned as a short run rather than separate trips.
