I think I persuaded my HVAC dude to try this one last time, because he's about to punch me from just hearing the word 'Nest'. His argument is "yes, but that piece of crap will control the relay!"...

So, the Nest's signal controls the switch between the red and white wire, correct?

Yeah, pretty much what my HVAC guy said right from the moment I wanted to install Nest. Not in those exact words, and with rich use of expletives, but the gist is what you said.

It IS a packaged furnace/AC unit, yes. Overall, my conversation with their support (level 1 and senior tech) was not useful, including how they went about asking me to swap the wires. Leaving the C...

I honestly didn't realize what it was she suggested, because I am not so clear on which wire does what, except C. If anything got damaged, it's on them now.

In my infinite stupidity per Nest tech's suggestion I swapped W1 and Y1 and tested heat, which I think turned the AC on in 20F temperature (the unit is in a cabinet on the patio). I turned it right...
