This page covers seven conferences worth knowing about, weighted toward HVAC, plumbing, and water management. The High-Performance HVAC Summit kicks things off in early September in Pigeon Forge, drawing contractors focused on system efficiency and field performance. Later in the month, the Nexstar Network Super Meeting in Aurora brings together service business owners working through growth and operations challenges. A few events run into early October, so the planning window is tighter than it looks. If you're building a fall trade show calendar, sizing up sponsorship slots, or trying to place a sales rep at the right regional event, this list gives you enough detail to make a quick call on which ones are worth the trip.
