An estimated 52,000 attendees, including 35,000 visitors, came to the Dallas Convention Center Jan. 28-30 for the country’s largest industry event.
They saw 1,951 companies taking up 397,000 square feet of trade show floor space.
“We were very pleased with the attendance and the enthusiasm on the show floor,” said Clay Stevens, president of the International Exposition Co., producer and manager of the AHR Expo. “The aisles were packed for almost all three days of the show.”
Many exhibitors said the show’s first two days were especially busy, noting that the final day typically sees a drop-off as people who came in for the expo start to head home.
Nevertheless, it was a good event, said Kevin Stamets, strategic marketing director for Trane.
“The show has been incredible — standing room only for us,” he said. “I had no idea we would be packed in our booth the way we were for two days.”
Brendan Sullivan of software company FieldAware agreed.
“AHR Expo has been a tremendous success for us,” he said. “We gained a wealth of new business leads.”
Foot traffic Jan. 28 especially impressed John Coakley, national sales manager with fabric ductwork manufacturer DuctSox Corp.
“The turnout on Monday was tremendous,” Coakley said. “We’ve had nice feedback from many engineers on DuctSox’s new SkeleCore line, which prevents textile duct sagging and wrinkling.”
Day two was no slouch either, according to officials with sheet metal contractor Semco and hydronics manufacturer Taco Inc.
“Traffic has been strong all day, mainly with consulting engineers,” said Semco President Nick Agopian. “Interest has been very high in our new eQ energy recovery ventilator for applications under 15,000 cfm (cubic feet per minute).”
Taco brand marketing director Mark Chaffee said his company’s booth display continued to be a crowd pleaser.
“It’s great to be back in Dallas,” he said. “Through day two, Taco is experiencing a great response at the show. Once more pushing the technology envelope in what we can bring to our booth, our giant video screen and iPad stands allow us to showcase our new innovation and development center and the range of products, software and educational opportunities Taco provides the industry.”
Officials with the American Society of Heating, Refrigeration and Air-Conditioning Engineers were also pleased with the attendance at its winter meeting, which was held in conjunction with the expo. ASHRAE said 2,840 people came to its meeting, representing countries as far as India, Latvia, Romania, Uganda and Thailand. Society sessions included presentations on energy consumption, maintenance and efficiency.
Overall, the success of this year’s show makes Stevens look forward to next year.
“We believe the enthusiasm on the show floor bodes well for the economic outlook of the HVACR industry overall, and AHR Expo 2014 next January in New York,” Stevens said.
Of course the AHR Expo included dozens of products of interest to sheet metal and HVAC contractors. Here is SNIPS’ list of many of the products that may be of greatest interest to readers.

Trane environmental affairs director Eugene “Smitty” Smithart led a Jan. 29 session for the Spiral Duct Manufacturers Association on the green benefits of using spiral duct.
Spiral is sustainable, group says
The AHR Expo offered several free education sessions to attendees, many of them focusing on a common theme — going green.
Whether the topic was using building automation to increase efficiency or retro-commissioning to monitor energy usage, the expo was definitely pushing sustainability.
The Spiral Duct Manufacturers Association sponsored one of these sessions to show how their members’ product can go a long way to make a building more energy efficient.
The Jan. 29 session, called “Green HVAC Ductwork Done Right,” was led by Eugene “Smitty” Smithart, a 35-year veteran of the HVAC industry and director of environmental affairs for Trane.
Smithart told attendees why spiral ductwork is an excellent choice for contractors and building owners looking to save on installation and utility costs.
First, Smithart said that spiral duct has a lower installation cost over rectangular duct because there is less material used.
“Isn’t that what green is all about?” he asked the audience.
Next, Smithart talked about duct leakage. He pointed out that with rectangular duct, there is a greater possibility of leaks to occur.
“Have you ever looked at it (rectangular duct)?” he asked. “Every few feet you have connections.”
Smithart said that if these connections are not carefully sealed or caulked, air will seep out.
So why is duct leakage so important? Smithart cited a study from the U.S. Department of Energy that looked at where existing buildings waste energy. At the top of the list was duct leakage. Leaky ducts, according to the report, account for a loss of $3 billion worth of energy a year.
Rectangular ductwork is still the primary choice when it comes to most sheet metal projects. Smithart believes this has to do with misconceptions and a lack of education. One of those is that spiral duct will cost too much or won’t fit in a certain space. Some spaces require multiple runs of round duct. But Smithart said that money can still be saved because spiral duct uses less metal. It also cuts down on the amount of sealant that is sometimes required for rectangular duct and the labor needed to apply that sealant.
He also said that for some veterans in the industry, “You will not touch their Trane Ductulator.”
Smithart said that the mission is to educate these contractors and show them that sizing spiral can be just as simple.
