I can’t seem to find the air conditioning lable

[Rickeyg]

I have a heat pump furnace . I have green red blue and white wires. I can’t seem to find how I hook up for air conditioning. 
my wires are connected as such

green is on yellow

red is on red

blue is on green

white is on white

it turns heat on but I can’t find air conditioning

what am I doing wrong?

Hello Rickeyg,

Thanks for reaching out here in the Google Nest Community. I'd be happy to take a look at this for you.
 

It seems like there might be a wiring mismatch causing the issue with your air conditioning. Generally, the standard color-coding for thermostat wires is:

• Green wire: G (fan)
• Red wire: R (power)
• Blue wire: C (common)
• White wire: W (heat)
• Yellow wire: Y (cooling)

In your case, it appears there might be some confusion in the wiring. To troubleshoot, ensure the correct wires are connected to the corresponding terminals on both the thermostat and the furnace. You can share with us your old thermostat and Nest Thermostat's wiring setup.

I'll look forward to your response.

Regards,
Mark
