The Requisition Technician visited this furnace.

That is all.

Visiting really was all Req Tech could do. That furnace has a variable speed blower motor. The licensed, bonded and five star rated RT said he isn’t trained to work on them and left. That’s like a plumber saying he isn’t trained to work on those newfangled low-flow toilets. Both the toilet and the motor came to widespread use in the 1990s. Every furnace manufacturer sells variable speed motors. Every real repairman works on them. And by “work” I mean we plug this tester in and flip a few switches. That’s really is all there is to it.
