Top HVAC Trade Shows to Attend in 2026

Your competitors are already booking their flights. They’re blocking off dates on their calendars, arranging coverage for their service teams, and preparing to invest thousands of dollars in registration fees, travel, and hotel rooms. They know something that many HVAC companies often miss: attending the right HVAC trade shows can transform your business in ways that years of grinding away in your market never will.

Smart HVAC business owners attend HVAC conventions to discover technologies that slash their operating costs, meet manufacturers who become their preferred suppliers, and build relationships with other contractors who become their most valuable advisors. Trade shows also expose you to new revenue strategies—from proven techniques for selling maintenance contracts to innovative service offerings that increase customer lifetime value.

This guide shows you which HVAC trade shows deserve your time and money—and exactly how to turn every event into measurable business growth.

Major HVAC Conferences and Expos in 2026

AHR Expo 2026

Dates: February 2-4, 2026
Location: Las Vegas Convention Center, Las Vegas, Nevada
Cost: Free registration

The International Air-Conditioning, Heating, Refrigerating Exposition (AHR Expo) is North America’s largest HVACR marketplace. With over 1,800 exhibitors, more than 50,000 attendees and 350 speakers, AHR Expo 2026 represents the single most comprehensive showcase of HVAC products, technologies, and innovations available anywhere.

What especially sets AHR Expo apart is the hands-on access to equipment before it hits the market. You’re operating controls, examining heat exchangers, and asking manufacturers the tough questions about warranties, lead times, and dealer support that determine whether new technology actually works in the real world.

ASHRAE Winter Conference 2026

Dates: January 31-February 4, 2026
Location: Las Vegas, Nevada
Cost: $885 – $1,440

The American Society of Heating, Refrigerating and Air-Conditioning Engineers Winter Conference, or ASHRAE Winter Conference,runs concurrently with AHR Expo, creating an unmatched opportunity for professional development. While the expo focuses on products, conferences dive deep into the engineering principles and technical knowledge that separate great HVAC companies from mediocre ones.

The half-day seminars and full-day courses offer intensive training that’s immediately applicable to complex installations and service challenges. For HVAC business owners serious about technical excellence, ASHRAE events provide access to the engineers who write the standards your work must meet.

ACCA 2026 Conference & Expo

Dates: March 15-18, 2026
Location: Las Vegas, Nevada
Cost: $445+ (member pricing varies)

Air Conditioning Contractors of America (ACCA) hosts the industry’s premier business-focused conference. While other events emphasize technical knowledge, ACCA 2026 Conference & Expo centers on the business strategies that determine whether your company thrives or barely survives.

The education sessions tackle hiring and retaining quality technicians, improving cash flow, and scaling operations without sacrificing service quality. The speakers are successful contractors who’ve built multi-million-dollar companies.

National HVACR Education Conference 2026

Dates: March 23-25, 2026
Location: South Point Hotel, Las Vegas, Nevada
Cost: $435

This HVAC conference focuses exclusively on technical education and hands-on training. The sessions cover emerging technologies like cold climate heat pumps, inverter-driven systems, and variable refrigerant flow systems that represent significant revenue opportunities for contractors who master them early.

Attendees are using diagnostic equipment, analyzing refrigerant circuits, and troubleshooting live systems under the guidance of master technicians. The HVAC conference also awards Continuing Education Units (CEUs) that maintain your certifications and licenses.

ASHRAE Annual Conference 2026 (ASHRAE Expo)

Dates: June 27-July 1, 2026
Location: Austin, Texas
Cost: TBD

ASHRAE’s Annual Conference, aka the ASHRAE Expo,covers building automation, energy management, sustainability, and integration with electrical and plumbing systems. The June timing works well for contractors looking to attend after the spring installation rush but before the peak summer service season.

The technical program includes forward-looking content about regulations and industry trends that affect your business two to three years out.

Service World Expo 2026

Dates: October 2026 (specific dates TBA)
Location: TBD
Cost: TBD

Service World Expo, hosted by Service Nation, brings together contractors from multiple trades—HVAC, plumbing, electrical, and other field service businesses. The conference emphasizes practical business growth strategies: marketing that generates qualified leads, sales processes that close at higher rates, and operational systems that scale profitably.

NOTE: Service Fusion will be exhibiting at the 2025 Service World Expo (October 28-29, 2025).

RYNOx Home Services Summit 2026 (RNOx HVAC Event)

Dates: February 18-19
Location: Phoenix, AZ
Cost: TBD

The RYNOx HVAC event is the home service industry’s most exclusive gathering, organized by RYNO Strategic Solutions. Unlike massive HVAC trade shows with thousands of attendees, RYNOx intentionally limits attendance to create an intimate environment where HVAC business owners can build meaningful relationships with industry legends.

The RYNOx HVAC event focuses on high-level business strategy: navigating acquisitions, implementing digital marketing that generates revenue, and building company culture that attracts and retains top talent. If you’re ready to move beyond operational tactics and start thinking about legacy-building and exit strategies, RYNOx delivers conversations you won’t find at other industry events.

Regional and Specialty HVAC Trade Shows

National HVAC conferences get the headlines, but regional HVAC trade shows often deliver better ROI for contractors serving specific geographic markets. These smaller events provide intimate networking opportunities, region-specific education on local codes and climate challenges, and facetime with the local distributors.

Build Expo USA hosts regional shows across major markets throughout 2026. While not HVAC-specific, these events attract the builders, developers, and property managers who hire HVAC companies for new construction and major renovation projects.

State and local HVAC association events rarely match the scale of national conferences, but they provide critical connections with local regulators, code officials, and industry leaders who influence your market.

Why HVAC Trade Shows Matter for Business Owners

The most successful HVAC companies in your market attend trade shows consistently.

• Technology adoption advantage: HVAC technology evolves rapidly. Contractors who attend HVAC conventions see new technologies 12-18 months before they become mainstream, giving you time to train technicians and establish relationships with manufacturers before your competitors even know these solutions exist.
• Vendor relationship building: At HVAC trade shows, you meet manufacturer executives who can negotiate better pricing, expedite orders during supply shortages, and provide co-op advertising funds—advantages you’ll never get from regional sales reps.
• Technical problem-solving: Trade show technical sessions and informal conversations with engineers provide solutions to installations that stump your entire team. The networking creates an informal advisory board of contractors who’ve solved the problems you’re currently facing.

How to Choose the Right HVAC Trade Show for Your Business

Not every HVAC convention deserves your time and money.
Smart selection requires evaluating each opportunity against your specific business situation and goals.

Match the HVAC conference to your business size.
If you’re running a 2-truck residential HVAC company, start with business-focused events like ACCA 2026 Conference & Expo that address operational challenges at your current stage. If you’re managing 50 technicians across multiple branches, consider exclusive events like the RYNOx HVAC event that focus on acquisitions and scaling strategies.

If you’re running a 2-truck residential HVAC company, start with business-focused events like ACCA 2026 Conference & Expo that address operational challenges at your current stage. If you’re managing 50 technicians across multiple branches, regional shows won’t offer enough substance to justify executive time.

Evaluate the exhibitor list carefully.
Review who’s exhibiting before registering—if it’s dominated by companies irrelevant to your business model, the networking value drops dramatically.

Calculate the true cost honestly.
Factor in airfare, hotels, meals, rental cars, and opportunity cost of time away from the business. A “cheap” local show that delivers limited value could cost more than an expensive national conference that transforms your business.

Start with one major and one regional show.
Most successful contractors build their strategy around one major national conference (like AHR Expo or ASHRAE Expo) plus their state association annual event. This provides comprehensive exposure to industry trends while maintaining local market connections.

4 Tips to Maximize ROI from Attending an HVAC Conference

Set specific goals before you register. Are you researching equipment? Looking for solutions to technical problems? Your objectives determine which sessions to attend and which exhibitors to visit.

1. Pre-schedule key meetings. Contact manufacturers and distributors you want to meet 3-4 weeks before the show. Request specific meeting times and come prepared with questions.
2. Attend with your team. Bringing your service manager or lead technician multiplies the value. You can divide responsibilities and create shared understanding when implementing changes after returning home.
3. Schedule follow-up before leaving. Put demo calls, proposal requests, and facility tours on your calendar with deadlines. Most trade show ROI comes from what you do after the event, not during it.
4. Implement quickly. Choose 2-3 specific changes to implement immediately after returning. Quick wins build momentum for larger initiatives later.
