Hi @lrgranger3!

Thanks for posting in the community.
I’m sorry for the inconvenience that you are experiencing whit your new Nest Learning Thermostat 3rd Gen. I can see that you just installed and you set it for cool but it is blowing hot air. Let’s solve this together. 

To better assist you, I need some extra information. Here are some questions for you:

• What kind of HVAC system do you have?
• Do you have a common ground wire or C wire?
• Do you have a picture of the wiring of the old and the new thermostat?
• What troubleshooting steps have you taken?

Check the next articles for further information: Troubleshoot strange heating or cooling behavior.

I’ll be waiting for your response.

Regards,

Daniel.
