Registration is now open for the Air Conditioning Contractors of America’s 2012 convention.

The 44th annual event, which includes the Indoor Air Expo trade show, will take place March 5-8 at the Paris hotel-casino in Las Vegas.

This year, the convention’s educational sessions will be either 45 or 90 minutes long, allowing members to get an overview or more intense education on some subjects. All sessions will be video recorded for members’ use.

“It’s impossible to remember everything you learn at an event like our conference, so as we have done in the past, we are offering a free DVD of all the sessions to attendees who register early,” said Paul T. Stalknecht, association president and CEO. “It’s a great way for us to thank them for attending and it helps them refresh their learning experiences, and share valuable information with the top leaders in their companies that may not have been able to attend. We will mail out the DVDs as soon as production is complete, to all attendees who either registered early to earn it for free or purchased a copy on-site.”
