CHICAGO — With the AHR Expo kicking off in Chicago today, Sunday was a time for hospitality suites and parties. Perhaps none rocked as loud as the Danfoss Customer Appreciation Event at the House of Blues.

Hundreds of Danfoss customers filled the venue to listen to Forget Hannah, a cover rock band from the suburbs of Chicago. The band provided a little something for everyone playing classic rock, blues, and even country. Food, drinks, and laughter flowed as this event went deep into the night.
