My nest is reading 2+ hours

[Bribri2]

My nest was working great and my apt started getting hot fast. I went to the thermostat and noticed when I place it lower from 75 to 73 (doesn't matter which number), it says 2+ hours. I didn't update nor do anything to it.

Hi Bribri2,

Thanks for reaching out. I'd like to help. When you manually change the temperature on your thermostat or with the app, you'll see approximately how long it will take for your home to reach the temperature you've chosen.

Your Nest thermostat will estimate the Time-to-Temperature in increments of five minutes. If it's less than ten minutes until the temperature you've selected is reached, the display will read, "less than ten minutes." If it's more than two hours, Nest will read "IN 2+ HR."

Once the target temperature is reached, the Time-to-Temperature will disappear, and the screen background will turn from orange (heating) or blue (cooling) to black.

The Time-to-Temperature estimate will get more accurate as your thermostat continues to learn how your home warms up and cools down.

Please let me know if you have further questions, as I'll be willing to assist you.

Best,

Jenelyn

I’ve had my nest thermostats for a couple years but one of them is taking forever - as in hours - to cool one or two degrees. It doesn’t matter what time of day, what temperature, etc - but as an example moving it to cool from 80 to 79 or 78 takes forever whereas my other thermostat does it within 10-15 mins.  The display on the “faulty” one always says 2+ hours.  

I’ve had the ac techs come and my ac is servicing regularly. They said it’s not the ac units but the thermostat creating issues.   

help!!!

Hi folks,

Thanks for letting us know. Could you please provide your Nest Thermostat power readings? Also, check your thermostat energy history. It might help you see what your thermostat was doing previously. You can visit this support article on how to check Energy History in the thermostat or in the Nest app.

You can follow the guide below to check your thermostat power readout:

Nest Learning Thermostat and Nest Thermostat E:

1. Go to your thermostat Quick View menu.
2. Go to Settings.
3. Look for Technical Info.
4. Select Power.

Nest Thermostat 2020:

1. Open the Google Home app tap the thermostat tap Settings .
2. Select the Device Information.
3. Choose Technical Information.

Regards,

Jenelyn
