Tony Mormino is joined by Louie and Peter from ABB to break down Variable Frequency Drives—what they are, how they save energy, and why they’re essential in today’s HVAC systems. From fan laws to harmonics to ABB’s new smart factory, this episode blends technical insight with real-world perspective (and a few laughs along the way).
