More than 300 HARDI (Heating, Air-conditioning, and Refrigeration Distributors International) members and guests attended the organization’s annual Icebreaker pre-party event Sunday from 4-6 p.m. at the Hilton Chicago. The event featured food, drinks, an open bar, and ample opportunities for members to mix, mingle, and network.

Unlike previous Icebreaker events, HARDI deliberately shifted the event time this year in order to give HARDI members the chance to attend the Icebreaker as well as the other numerous evening events being held around the city in conjunction with the 2015 AHR Expo, which officially begins Monday.
