I’m Michael Russo, creator of the YouTube channel Jersey Mike HVAC. For over three decades I’ve worked as an HVAC technician installing and servicing residential systems, and as an industrial Stationary Engineer operating coal, oil, and natural gas–fired power plants—managing up to 2,000 megawatts on the power grid in the NYC area.

  Today, I spend much of my time sharing that experience, helping anyone eager to truly understand HVAC.

  My teaching always focuses on the why, not just the what. By breaking HVAC concepts into clear, real-world examples, I help make complicated systems finally make sense.

  This website extends that mission—providing simple explanations, practical tips, and resources like schematics and guides you can actually use in the field.
