HVAC 2025

HVAC course starts, as many other courses, with discussion about Ohm Law as some AC issues are electrically based.  Ohms Law also serves as an analog for how HVAC systems work and meshing the two together here helps techs understand both.

The AC machine (i.e. Robinair, etc) is also a major topic covered as it is often abused and only partially functional – making it impossible for a positive diagnostic outcome.
