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

  Today, I spend much of my spare time sharing my experience to help anyone eager to truly understand HVAC.  This website extends that mission—providing diagnostic training, calculators, lessons and resources you may need when out in the field.
