Thermostat set to heat & blowing cold air

Set to heat, but the nest thermostat is blowing cold air.

Is this a new install or one that stopped working?

Post a picture of the original thermostat's wiring here if you have it

I'm having the same issue. It worked fine switching from cooling to heat this past winter, but when I tried switching it back to cooling it kept blowing heat. had a tech come out and they said they reset the nest and it was working correctly. Now when trying to switch it back to heating it's still blowing cold air

Hey folks, 

Thanks for responding here, Patrick_Caezza. 

To everyone, in order to dig deeper into this, please let us know if you encountered this concern right after installing your Nest thermostat or has it worked previously? Also, we need you to provide photos of your original thermostats wiring and your current Nest thermostat one. 

If you could provide a rundown of the steps that you've tried, we'd appreciate them as well. 

Best,

Hey Bottohome, 

Sorry if you feel that way. Please provide a photo of your old thermostat wiring as well as your current Nest thermostat wires so we could have a look. 

Best,

Hey there, 

It's me again — have you had the chance to take the photos being requested above? If yes, please post it here so we could keep the ball rolling.

Hi, 

Since it's been a while since this thread was last updated, we'll be locking it if we won't hear back from you again within a day. Should that happen, feel free to create a new one if you have more questions or have other concerns in the future. 

Best,
