HVAC Conferences and Trade Shows in 2020

Check out our comprehensive list of the biggest HVAC trade shows and conferences in 2020.

Every year, dozens of HVAC conferences and events go down in the US and Canada. These expos offer chances for continued training, professional networking, and technology scouting/vendor research. While you probably can’t make it to every show every year, attending a big event in your area or going out of your way to hit AHR every couple years could prove beneficial in a lot of ways.

HVAC represents a huge, ~100 billion dollar industry, so many conferences and events have sprang up for it over the years. We’ve compiled a list of the most notable 2020 shows below. Find one in your neck of the woods (or one happening in a place you wouldn’t mind visiting), and start making plans to attend!

AHR Expo

Number of Attendees: up to 72,000

2020 Dates: February 3-5, 2020

Location: Orlando, FL

The AHR Expo bills itself as the “largest HVACR event” and moves to a different city every year. In 2019, Atlanta played host, attracting more than 27,000 attendees and 18,000 exhibitors (including us!). The year before, Chicago hosted the expo and smashed attendance records for the event. Visitors and exhibitors together totaled over 72,000. At AHR you can find practically every HVAC company in the world (from HVAC system manufacturers to software providers to supermarket refrigeration specialists) and get lost in one of the convention’s sprawling exhibit halls.

Eastern Energy Expo

Number of Attendees: 4,300

2020 Dates: May 17-20, 2020

The Eastern Energy Expo will go down at the Mohegan Sun in 2020.

2020 Dates: April 21-22, 2020

ASHRAE Annual Conference

Number of Attendees: 1,600

2020 Dates: June 27-July 1, 2020

ACCA Conference & Expo

Number of Attendees: 1,000

2020 Dates: March 16-18, 2020

The Air Conditioning Contractors of America (ACCA) Conference and Expo is a popular event. Nearly 1,000 people attended the ACCA Conference in 2019. Subjects covered included: employee retention, recruitment, digital marketing, and legalized marijuana as well as substance abuse. The 2019 Conference was held in San Antonio, but the event moves. The ACCA 2020 Annual Conference will take place March 16-18 in St Louis.


Number of Attendees: 1,000

2020 Dates: February 10-14, 2020

More than 1,000 people attend CampusEnergy every year. This event focuses on the design and maintenance of the HVAC systems used in colleges as well as those in airports, hospitals, and medical campuses. While this event may not be a great fit for residential HVAC companies—unless you are looking to implement green solutions in your service area—it is a good event for commercial HVAC companies to attend, even smaller firms.

PHCC Connect 2020

Number of Attendees: 800

2019 Dates: October 2-4, 2019

Location: Indianapolis, IN

This is a good conference for you to attend if you want a variety of workshops and training. Around 800 people attend the event, so hands-on sessions are a little smaller than they are at some other conferences. PHCC Connect offers over 20 education sessions as well as a product showcase so you can preview all the new technology coming on the horizon. You will find speakers as diverse as economists who can talk about trends to expect and Richard Trethewey of “This Old House.” For race car fans, the closing event is at the Indy 500 Speedway.

PHCC Connect 2019 is co-located with the 2019 RSES Conference & HVACR Technology Expo. Dates for 2020 have not been announced yet.
