Nest Thermostat – Frequently Asked Questions

thermostat installation

While the Nest thermostat may look like a regular programmable model, it is very different. The Nest thermostat was designed by Tony Fadell and his team of engineers at Nest Labs. Tony Fadell founded Nest Labs with the mission “to create a conscious home.”

The Nest Thermostat has been described as the iPod of home heating and cooling products. Nest is an intelligent thermostat that Nest Labs claims is 30% more energy-efficient than a standard programmable model heating and cooling system.

Can I Install a Nest Thermostat Myself, or Do I Need a Professional Nest Thermostat Installer?

For those who have Nest Thermostats, you should know that Nest thermostats are very easy to install. Nest provides the users with a complete installation guide for Nest Thermostat installation. People aware of the Nest Thermostat features and who have experience installing Nest thermostats can save on installation charges.

Nest Thermostat Installation Service Providers are available via some online websites that offer Nest thermostat installation services at actual Nest Professional Program rates and even much more affordable prices. However, you can contact Nest thermostat installers to perform Nest thermostat installation since they charge a reasonable amount for a standard Nest Thermostat Installation.

Do You Need an Electrician to Install a Nest Thermostat?

The Nest Learning Thermostat™ Installation is easier than you think. It’s easy to install Nest if you have experience doing basic home repairs and projects. The Nest thermostat may be installed on any wall in your home. Nest is tool-free, so you don’t need to mess with wires or a power drill. Nest has an integrated magnet for easy, secure mounting. Nest’s built-in sensors detect level and flush against the wall, so installation is simple and accurate.

You can do it yourself, but Nest recommends that a Nest-Trained Pro installs Nest. Nest-Certified Professionals are the only people with specialized training and access to technical support from Nest experts.

Does the Nest Thermostat Have to be Hardwired?

Nest thermostat can be installed either hardwired or wirelessly, and Nest is also available in a battery-powered model. Nest Thermostat can be powered by AC power (through an AC outlet) or Nest Power Adapter (a rechargeable Lithium-Ion battery). Nest thermostats are designed to run on any voltage from 110V to 240V. Nest thermostat installations are easy for both hardwired and wirelessly Nest thermostats. Nest thermostat has a built-in Nest Pro installer tool kit, which comes with a step-by-step Nest Thermostat installation guide.

Does the Nest Thermostat Require C Wire?

The Nest thermostat comes with built-in Wi-Fi connectivity to communicate with the Nest app on your phone. It also supports Power Extender Kit to connect Nest Thermostat to C-wire. Nest thermostat is designed with a series of sensors that can detect temperature and other conditions in the room. Nest does not require a C wire, which means it will still work effectively even if you use a Nest without a C wire. Nest Pro installer Tool kit comes with Nest Thermostat installation guide and Nest Learning Thermostat Nest install tool kit to make Nest thermostat Nest installation as easy as possible.

How Many Zones Can a Nest Thermostat Control?

Nest Thermostats can control up to 32 Zones if Nest is wired in through a 24-48VAC transformer. They should be wired together, and Nest’s C wire should be connected to the same circuit as the other Nest devices.

If you are using Nest Thermostat with a Heat Pump or Gas Furnace, Nest Thermostat will only control Nest in Heat settings. Nest will not control Nest in Cooling, Auto, or Off modes.

Where Does Blue Wire Go on Nest Thermostat?

There are two wires that Nest does not use with the Nest thermostats that may be confusing to installers. The Blue and White wire pair are not utilized in Nest thermostat installations because Nest has no contact closure on the unit itself, so there is no way for it to communicate with the HVAC system outside of Wi-Fi. Nest thermostats only use the Red wire to control power in the Nest unit, and all other cables are not used.

Can Nest Thermostat Work Without Wifi?

Nest thermostat can work without wifi. It does not require an active internet connection to operate correctly. Nest thermostat connects to your smartphone and the Nest server via Bluetooth technology. So, you don’t need a working internet connection for Nest thermostat installation. Nest thermostat will still work typically if the Nest server and the Nest smartphone app are not working.

How Do I Use My Nest Thermostat Without Power?

You can still use Nest if your power goes out or you’re working on a rewire. Just set Nest to its C° mode (the little sun icon). Nest will remember the temp you’ve chosen and then apply it when power is back on. Nest will run down its battery a little faster in this mode, and you won’t get weather updates. Several Nest owners have even suggested using Nest for emergency heating if your power goes out.

Does a Nest Thermostat Have a Battery?

Yes, Nest thermostats have a rechargeable lithium-ion battery. The Nest thermostat only works if it’s connected to power, but the Nest has five days worth of built-in backup power so that you don’t lose your programming or Nest Leaf settings in case of a power outage. Nest stops drawing on this backup power after five days. Nest’s backup power is supported by both a wall plug and an internal rechargeable battery.

Does a Nest Thermostat Save Money?

Nest Thermostat will help you save on your Nest installation cost by using less energy to heat or cool your home. Nest Learning Thermostat also calculates how much energy it has saved and shares this information with you in the Nest app.

If you have Nest installed on a 5-year old AC unit, Nest will do all the work of automating your HVAC (Heating, Ventilation, and Air Conditioning) unit. Nest will control the fan speed (if your AC has a variable-speed compressor). Nest will also preheat or cool your home before Nest predicts you’ll arrive on a Nest app. If Nest registers that you and the family are away for long periods, it won’t use any energy to heat or cool your house. Nest has full support for entirely 8-stage systems, including gas furnaces and air-to-air heat pumps. If you own a Nest Learning Thermostat, get used to saving money on your electricity bill!

How Long Do Nest Thermostat Batteries Last?

Nest Thermostat batteries typically last between 2 and 3 years. Nest thermostats usually don’t use a lot of energy. This is why Nest thermostats are a good choice for people who want to lower their home’s energy consumption but don’t want to sacrifice the convenience of remote control heating and cooling. The Nest thermostat also uses power to control your air conditioner, fan, humidifier, dehumidifier, and furnace.

How Does Nest Know You Are Not Home?

Nest Thermostat uses several methods to identify when you are not in your home; this ensures Nest only operates at times when the thermostat should be active. Nest can detect movement through its built-in occupancy sensor and external weather sources like wind speed, humidity, and precipitation levels.

Nest also knows whether or not you’re home based on the Nest App. If Nest has been linked to your Nest Account, and Nest confirms that you are not home when Nest should be active, Nest will go into a “Home/Away Assist” mode in which Nest takes over for your regular thermostat until it sees you’re home again.

Nest’s Home/Away Assist mode is not just about saving energy either; the Nest thermostat can bypass preheat or dehumidify (depending on whether Nest is set to heat or cool) when Nest senses that you’re not home. Undeniably, it is one of Nest’s best features. Nest will take over for your regular thermostat until it sees you’re home again and resumes its normal schedule. Nest will then bring the temperature to your desired settings when it sees you are back, saving energy and keeping Nest comfortable.

According to Nest research, Nest’s Home/Away Assist mode reduces Nest’s energy consumption by an average of 10% compared to a typical thermostat (when used with Nest Protect). Nest can continue to run in Home/Away Assist mode until Nest is removed from its base or Nest’s batteries are replaced. Nest will also turn itself off if Nest senses an extended period without homeowner activity, which Nest researchers say Nest Thermostat does 500 times per year on average.

Does The Nest Thermostat Have a Camera?

No, Nest does not have a built-in camera or any way to connect to one. The Nest app has an optional Nest Aware service that allows the Nest thermostat to interact with Nest Cam for hands-free temperature monitoring and controlling your Nest Thermostat without having to look at it. Nest Cam is Nest Labs’ indoor/outdoor security camera with audio and video recording capability. Nest Cam is available in Nest’s retail stores, online at, or on Amazon.

Does the Nest Thermostat Detect Pets?

The thermostat doesn’t detect any motion other than human movement. That doesn’t mean that it can’t tell the difference between a flashing laser pointer and your pet, though. The difference is made during setup, where you can choose whether or not to tag pets as family members. Suppose Nest works with most pets. Nest works on several levels – motion, sound, and heat to detect whether or not there’s somebody in the house. Nest will learn your schedule over time and understands when you’re home and when you’re not there so it can save energy while you’re away.

Can 2 Nest Thermostats Work Together?

Yes, Nest Thermostat can work with other Nest products. Nest has a series of Nest Products that can work together to make life better and more accessible for the users: Nest Protect, Nest Cam, and Nest Learning Thermostat. All of these devices are compatible with each other.
