Nest heat blowing while on cold - worked fine six months ago and switching B/O doesn't fix it

[circles13]

Hello, just tried starting the cooling function for the first time this spring and hot air is blowing. Same Nest, same install, and it worked fine at the end of last summer. I tried switching the B/O configuration, but neither configuration results in cool air. Help!

Hi circles13,

Thanks for reaching out. I understand that when you activated the cooling, it blew heat. I am happy to assist you! Before continuing, I need to ask some questions to better understand your situation.

• What type of Nest thermostat do you have?
• What type of system do you have? (Heat pump or conventional type)
• Could you please send me a picture of your wire labels connected to your Google Nest thermostat?

I will be awaiting your response.

Regards,

Manuel
