The International Air-Conditioning, Heating, Refrigerating Exposition (AHR Expo) is a leading heating, ventilation, air conditioning and refrigeration (HVACR) event. Each year, the event consists of more than 2,100 exhibitors and attracts more than 60,000 attendees. 

The 2019 AHR Expo, co-sponsored by the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) and the Air Conditioning, Heating and Refrigeration Institute (AHRI), is January 14-16, 2019, at the Georgia World Congress Center in Atlanta, Georgia.

Since 1930, the show has provided a forum for the HVACR industry where OEMs, engineers, contractors, manufacturers, distributors and educators in commercial, industrial and institutional facilities come together to discover the latest products, learn about new technologies and develop mutually beneficial business relationships.

What to expect

Exhibitors display new solutions that serve HVACR functions ranging from highly efficient equipment and components to whole-building management systems, such as building automation and control technologies that connect and communicate via the Internet of Things (IoT), and time-saving tools and instruments that require less time at the job site and many additional products and solutions that support efficiency.


AHR Expo 2018

The show features thousands of products in more than 770 categories, such as heating systems, air conditioning units, refrigerating equipment, ventilators, ducts, and fans, indoor air quality (IAQ)-related products, including filters, building automation, controls, networking and energy management systems, radiant heating, hydronic systems and plumbing products, tools and instruments, software for HVAC design, estimating and service/business management, and solar, geothermal and other renewable-energy-related products.

Show floor sections

There are three product sections within the show floor: the Building Automation and Control (BAC) showcase, which will focus on building automation, climate control and IoT technology; the Software Center, designated for HVACR-related software, project and field service management and systems design; and the Indoor Air Quality Association Pavilion, which will showcase products related to IAQ to member companies. 


AHR Expo 2018

HVACR products on display include:

  • IAQ diagnostic instruments that guide HVAC professionals through the entire measurement process for more accurate reads and more timely detection of air quality issues
  • Evacuation hose delivering a conductance speed of 16 CFM at 1,000 microns, resulting in vacuum speeds up to 80 times faster than standard ¼-inch I.D. hoses and up to six times faster than other vacuum-rated hoses
  • Software application that supports HVAC professionals via a downloadable iOS and Android mobile app that can be used to create on-site customer reports and is inclusive of graphical data and airflow “grades” based on the simple input of nameplate information and two static pressure values
  • Water-cooled centrifugal chiller that supports low global warming potential (GWP) via improvements in compression and integration of variable speed technologies, specifically designed to meet customer demand, lower energy costs and reduce environmental impact
  • Fabric air duct system that improves end air dispersion, designed to replace traditional ductwork, insulation, diffusers and air valves with more even airflow that results in better energy efficiency and lowered operation costs, as well as easy installation and product maintenance
  • Internet-enabled wireless thermometer that uploads and stores temperature readings on the cloud and has the ability to send automatic alerts for extreme low or high readings directly to the user’s phone or tablet, and it can store up to 12 months of data for efficiency evaluations throughout the year
