compatibility check

[AaronSantiago]

Hi I recently got this nest thermostat but it seems unclear if its compatible with my house's system. The Sku for the nest is GA01334-US. Here is also a photo of my current wiring

You need to give access to the link.

I updated the link access so it should be visible now

That's some interesting wiring you have there.

Do you have access to the furnace/air handler?

The two wires on the Y terminal are of interest to me. We need to figure out what each is connected to.

Take a clear picture of the wiring in the furnace/air handler and post it here.
