Nest Thermostat Gen3 won't work with York furnace/thermostat that has A-wire.

Nest Thermostat Gen3 won't work with York furnace/thermostat that has A-wire. Called Johnson Controls & was told there is an adapter that makes my thermostat compatible with most 3rd party thermostats.   Anyone know about this or how to obtain adapter?

Hey Patsyk9, 

Sorry for the delayed response but thanks for posting. 

If you're pertaining to a Nest Power Connector that acts as a substitute for a C wire, you can check this out: https://bit.ly/3z34z2e Otherwise, you need to contact OnTech Smart Services to check your HVAC system what specific adapter is necessary to have it work with our Nest Learning Thermostat. 

Best,
