Google Nest is a unique device that makes your life easier by allowing you to remotely access and manage media, tasks and control items in your home: speakers, smoke detectors, thermostats and even your air conditioner.

So when the days get a little cooler and the need to have the air conditioning running lessens, using your Nest app on your phone, PC, or through your Amazon Echo to control the air conditioning can be great.



But things get a little tricky when it comes to turning off the air conditioning using Nest. This article will show you step by step how to turn off your air conditioning with Nest using different devices. Let's dive.

How to Directly Turn Off the Air Conditioning on the Nest Thermostat

There are several ways to turn off your Nest Thermostat. One of them interacts with the device itself. This method is relatively simple and involves using your Nest device screen. Here's how to go about it:

  1. Press your Nest thermostat until the main menu appears on the screen.
  2. Turn the silver dial to scroll through the menu until you reach "Thermostat". Once 'Thermostat' is highlighted, tap the device to select it.
  3. Using the wheel again, scroll through the options to select "Disabled".

The Google Nest Thermostat also offers the option to turn the heating on or off or use a feature called "Heat-Cool", which regulates the temperature in the room based on outside weather conditions.

How to turn off the air conditioning on a nest from the iPhone app

Another way to manage your Nest thermostat or air conditioning is to use the Nest app. This application can be downloaded from the Google Play Store or the Mac App Store and will allow you to control your Nest device remotely. For example, to turn off your Nest AC using your iPhone, you'll need to follow these steps:



  1. Open the Nest app.
  2. Locate your "Nest Thermostat" and select it.
  3. At the bottom left of this screen, tap the icon labeled “Cool”.
  4. In the new list of options, click "Turn off" to turn off your Nest AC.

If you want to turn off your air conditioning and heat the room instead, you can always choose the “Heat” option instead of turning off the device. Selecting "Heating" will allow you to set the Nest Thermostat to a higher temperature.

How to turn off the air conditioning on a Nest from the Android app

Maybe you have an Android device instead of an iPhone. You can still use the Nest app because Google makes it compatible with iOS and Android devices. Simply download it from the Google Playstore and install it on your Android smartphone. Once the app is installed, you can use it to turn off your Nest AC using this method:

  1. Open the “Nest” app.
  2. On the main screen of your “Nest” app, tap on the “Thermostat” option.
  3. At the bottom left, tap on the option labeled “Cool”. (If you have the heater on, it will say "Heat" instead of Cool.)
  4. In the new list of options, find "Disabled" and tap it.

How to turn off the AC on a Nest from a PC

If you prefer to control your Nest app from your PC, you have that option too. Here's how to turn off your Nest AC using your PC:


  1. Sign in to your Nest account at home.nest.com.
  2. Locate the "Thermostat" and click on it.
  3. Navigate to the “Mode” option and click on it. If your thermostat is set to AC, then the "Mode" is usually specified as "Cool".
  4. In the new set of options, click "Disabled".

How to turn off the air conditioning on a nest from an echo

Another way to control your Google Nest Thermostat is by using your Amazon Echo and Alexa. You will need to ensure that these two devices are properly configured and linked. But once they are, there's a range of Nest devices you can control when you're out or at home. Here are the steps to turn off the air conditioning on a Nest from an Echo:


  1. Once your Nest device is on and connected to Alexa, say loud and clear, “Alexa, turn [thermostat name] to off mode.
  2. Alexa will repeat the command to you to clarify, and it will sound something like "Turn [thermostat name] to off mode."
  3. Confirm your selection to deactivate the air conditioning.

Additional FAQs

Why doesn't my AC turn off immediately when I turn it off on my Nest?

If you turn off your air conditioning on your Nest and it doesn't turn off immediately, this could be happening for a number of reasons.

External conditions

The most common cause is that the outside temperature is high and your air conditioner is trying to keep the inside temperature at what you have set on your thermostat. Try turning your thermostat up 5-10 degrees and see if your air conditioning turns off after that.


Here's how to set the air conditioning on your Nest Thermostat:

1. Open the Nest app on your phone.

2. Press the "Thermostat". On the screen that opens, you will see the “Thermostat circle”.

3. Press it, then press the “Up” or “Down” arrows to adjust the temperature.

If you want to adjust the temperature of your Nest Thermostat using the device itself, just turn the outer silver dial left or right to raise or lower the temperature. The display on the screen will show the new temperature you have set.

Safety temperatures

Another reason why your air conditioning might not turn off is that Nest uses a unique feature called "Safety Temperatures". This application is designed to protect your home in the event of extreme outdoor temperatures.


So while you may have turned off your Nest thermostat, if outdoor conditions reach a particular temperature, Nest will activate "safety temperatures" to keep your air conditioning on or your heating to maintain a comfortable indoor environment.

Here's how to disable this feature in the Nest app:

1. Open the Nest app.

2. Locate the “Settings” app. (the gear icon.)

3. Tap on the “Equipment” option.

4. Choose “Safe Temperatures”.

5. Drag the two sliders to disable the settings.

Here's how to turn off "safe temperatures" on the Nest device:

1. Tap the screen to call up the “Quick Menu”.

2. Rotate the outer dial to highlight the 'Settings' option and press the screen to select it.

3. Select "Equipment". An “Equipment Detected” screen will appear.

4. Press "Continue".

5. Choose "Continue" again on the "Your System" screen.

6. Select "Safe temperature".

7. Use the wheel to select "Disabled".

8. Press "Done" to exit.

Now that you've turned this feature off, Nest won't automatically turn on your air conditioning or heating systems.
