The Biggest HVAC Trade Shows to Attend in 2026

AHR Expo 2026

AHR Expo 2026

The AHR Expo runs bigger than anything else on the calendar. This HVAC show puts hundreds of manufacturers under one roof, with live air conditioner system demos and refrigerant-ready equipment you can actually handle and review before it hits distributor shelves. Plus, you can talk directly with the engineers who designed them

ACCA Annual Conference

ACCA Annual Conference

The ACCA Annual Conference isn't about product demos. This HVAC convention is built for business owners: sessions run deep on financial management, leadership, and scaling a company that holds up in a tough labor market.

PHCC Connect

PHCC Connect

Running both Plumbing and HVAC means double the complexity. PHCC Connect is the HVAC tradeshow built with dual-trade contractors in mind, offering targeted sessions, structured roundtables, and supplier access that addresses both sides of the operation.

ServiceTitan Pantheon

ServiceTitan Pantheon

Pantheon pulls in contractors who want their software working harder. One of the more operationally focused HVAC expos on the calendar, it covers dispatching systems, automated workflows, and reporting tools that cut the admin overhead most shops quietly absorb every day.

Why You Need to Attend HVAC Conferences This Year

The ROI case isn’t complicated. One direct conversation with a manufacturer rep can save thousands on an equipment decision. Seminars cover technician recruiting, heating system updates, and financial planning built specifically for contractors. Then there’s floor time: validating new heat pumps and air conditioner systems hands-on before you commit any budget. That combination is hard to replicate from a desk.

BenefitWhat You Get
NetworkingFace time with manufacturers, distributors, and peers you'd never otherwise reach
EducationSessions on recruiting, financial management, and compliance you actually have to worry about
GearTry new heating equipment and air conditioner systems before the purchase order goes out

Frequently Asked Questions

What is the largest HVAC convention in the US?

The AHR Expo is the largest by far. It pulls 50,000-plus attendees and more than 2,000 exhibitors annually. No other HVAC convention is close.

Are HVAC trade shows open to the public?

Most require proof of trade affiliation at registration. National events are built for licensed contractors, business owners, and industry professionals, not general consumers.
