AHR, Around the Web, Training opportunities
This year the Show floor exhibited 1,824 companies from across the entire industry, including 497 international exhibitors.

Best of AHR 2019

The show’s return to Atlanta featured innovative products, a wide array of educational sessions, and network opportunities galore.

The 2019 Air-Conditioning, Heating and Refrigeration Exposition returned to Atlanta for the first time since 2001 and was a big success by almost any measure. This year the Show floor exhibited 1,824 companies from across the entire industry, including 497 international exhibitors. 

And this year for the first time the AHR Expo used radio-frequency identification (RFID) technology to verify attendance. This allows for the scanning in of each person without stalling the crowd and creating long wait times. (In previous years the Show relied on pre-registration and on-site registration to quantify attendance.) 

All of which means that the Show was able to generate a true capture of every attendee that walked through the door, and well as track data from time spent on the exhibit floor and time spent in sessions. The 2019 numbers are strong, with a total verified attendance of 45,078. 

“The HVACR industry is in a very exciting position at the moment and that energy was evident on the Show floor this year,” said Mark Stevens, show manager of AHR Expo. “Attendees came from all over the globe and from every corner of the industry to make this Show a success. We’ve received great feedback on the quality of networking from both attendees and exhibitors and look forward to seeing many of these connections come to life in the products and technologies on the Show floor in Orlando next year.” The 2020 AHR Expo is scheduled for February 3-5 at the Orlando Convention Center. 

The Expo is co-sponsored by ASHRAE and AHRI, endorsed by a host of industry leading organizations, and is held concurrently with ASHRAE’s Winter Conference (see our cover story, ASHRAE Wraps Successful 2019 AHR Expo).

Educational Sessions 

Smart home: Best opportunities research
Presenter: Continental Automated Buildings Association 

Research unveiled at AHR Expo pinpointed the best course forward for smart home technology deployments. The upshot: multi-dwelling units (MDUs) remain underserved due to the varieties of end-user requirements. At the same time, they sit at the intersection of the single family—who benefits most from smart home innovation—and commercial buildings, sharing characteristics of each. Importantly, MDUs have the size to invest in new technology, a stronger connection to resident satisfaction and more direct involvement of senior management for investment decisions. This makes MDUs the sweet spot where smart home innovation and experimentation can take root. 

Low Cost Leads are Hurting Your Business
Presenter: Women in HVACR 

The opening slide from Erik Wytrwal’s AHR presentation.

Erik Wytrwal, a consultant with Stochastic Marketing, a data analytics company designed specifically with HVACR and plumbing contractors in mind, discussed low cost/low value leads versus higher cost/higher value leads. All leads are not created equal, and rather than generating more business, low-value leads can end up driving your business into the ground.

Buildings and employees: How better buildings improve productivity and job satisfaction

New research presented at AHR Expo showed that building quality ranked second in contributing to employee satisfaction and productivity when benchmarked against other traditional employee perks such as bonuses, fitness benefits and flexible work hours. Only private work offices topped building quality by a slim margin. Since 80% of most organizations budget is spent on staff and 10% on buildings, spending more on providing a quality work building environment to get more loyalty and productivity from staff makes sense. (Presenter: Continental Automated Buildings Association.)

Distribution Efficiency: The Often Overlooked Advantage of Hydronics Technology
Presenter: The Radiant Professionals Alliance

This session, conducted by John Siegenthaler, first defined the concept of distribution efficiency, then compared the distribution efficiency of properly designed and poorly designed hydronic systems to that of forced air and VRF systems.
