The Institute of Heating and Air Conditioning Industries’ 31st annual trade show will take place next month in Pasadena, Calif.

The show, which organizers say is the largest annual HVAC event in Southern California, will be held from 11 a.m. to 8 p.m. Nov. 17 at the city’s main convention center.

“If you want to know what’s going on in the industry, you need to be at this show,” said Lyman Lockwood of Calif.-based George Haney & Son, and the association’s president. “It gives contractors a great opportunity to network with other industry leaders, as well as a chance to check on the latest innovative ideas.”

Besides dozens of new products on display, free business seminars will be available to attendees.

“Attendance at the trade show is a necessity for anyone engaged in the heating, air conditioning, refrigeration and sheet metal industries,” said Jim Miyao of the Southern California Gas Co. and IHAC’s trade show chairman. “There is so much to see and so much to learn about. It’s an important day for individual businesses, and for the industry at large.”
