The AHR Expo featured heat pumps in nearly every booth
It was my first time back to the AHR Expo after a four-year hiatus, and it was just as exciting as I remembered it. But, still, a lot has changed too. For instance, last time I attended the show, in 2019, IAQ was just starting to become a focus. The COVID-19 pandemic put IAQ in the spotlight, though, and now, there are several AHR exhibitors solely focused on improving the quality of indoor air.
