I had a look at the furnace blower fan motor in my 2023 construction home. It has some very cheap looking digital controller system with a ridiculous amount of complexity around it. There are 2 separate computers involved somehow. Just for spinning the blower. I was operating under the impression that an induction motor could be powered directly from the AC mains. The complexity is certainly not adding to any sort of comfort, etc. The overall system is unbelievably noisy. This is all so clearly engineered to require as much maintenance as possible on purpose. It would take me months of figuring to determine how to take 2 wires and turn them into 40. The easy part is throwing it into the plenum in such a way that the wires hang within millimeters of the rotating assembly.
