I finally had an AC guy get out here (today).... sounds as though it was
a damper issue (not Nest-related). Which is unfortunate, as replacement
+ time = $1,500.
I’m having a similar problem - but I know it can’t be the HVAC guy. We
have two zones/two nests. But it’s been working fine for several years.
all of a sudden today, the upstairs zone won’t work. I turn on
Downstairs, and air pumps out the downstairs...
