I’m replacing a nest with a nest I wired the new one the same as the old one but now the ac turns on in heat and the heat turns on for ac

Feel free to send images of the old wiring and the new to have another pair of eyes verify. On the surface it sounds like W1 and Y1 could be reversed. Also double check on the thermostat to make sure fuel source and system type are matching your HVAC system.
