Hi Lucilarg84,

Thanks for reaching out. I understand you're wondering if your HVAC system is compatible with a Google Nest thermostat. I'm happy to help!

Before I can assist further, I'll need some more information about your HVAC system. Please let me know:

• Do you have a heat pump?
• Does your system have emergency heat?
• Is there a C terminal connection on your current thermostat?

I look forward to your response.

Regards, 

Manuel
