Are Carrier AC / Furnace "Performance" systems compatible with Nest Learning thermostat 4th gen?

[TallJeff]

I received a Nest Learning Thermostat 4th gen as a gift and I love it! Sadly, the 21-year old Luxaire AC and furnace that came with our house need replaced. I'm looking at purchasing Carrier performance series AC and furnace to replace them, but the installer says I'll have to use an ecobee thermostat because Nest isn't compatible with Carrier performance. I tried to verify that online but everything assumes you already have the system and can look at the wiring. I haven't bought the system yet, so I can't look at the wiring to confirm compatibility. Can someone please tell me if the Nest Learning Thermostat 4th gen is compatible with Carrier performance series AC and furnace? 

If Carrier performance isn't compatible, is Carrier comfort series compatible? Or do I need to look at a different HVAC line?

Hi @TallJeff,

Thanks for reaching out to the Nest Community. I understand you're planning to purchase a new Carrier Performance AC series and want to ensure it will be compatible with your Nest Learning Thermostat (4th gen). I'd be glad to share more details with you.

To get the most accurate compatibility information before you buy, here's what I recommend: Get the exact model number of the Carrier Performance AC series unit you are considering. Then you can consult a Carrier installer or HVAC professional; they can provide definitive compatibility information based on the specific model and your existing Nest Thermostat. Once you have the basic information about the type of wiring and model, you can use the Nest Compatibility Checker.

Feel free to keep us posted if you have more questions.

Best regards,

Gabriela
