How Do Smart Thermostats Work to Cool and Heat Your Home?

Smart thermostats are a step up from programmable thermostats. In recent years, people have been increasingly turning to them to gain more control over their indoor environment. Read on to learn more about how these smart devices work.

The Basics

A smart thermostat connects to your Wi-Fi network for advanced functionality. You can control it remotely using devices like phones, tablets, and smart speakers via a companion app.

When you use the app to enter a temperature setting, it transmits the setting to the thermostat through the Wi-Fi network. The thermostat, in turn, sends the signal to your HVAC system.

If you adjust the thermostat using a smart speaker, the smart speaker’s app communicates your voice command to the smart thermostat’s companion app. The command then travels through your Wi-Fi to the thermostat.

Depending on the model, a smart thermostat can offer a variety of other impressive features.

Learning Algorithms

Some smart thermostats have learning algorithms. While you can input your schedule with these thermostats, they can also learn your schedule, as well as your heating and cooling habits, over time. They then adjust themselves automatically based on your preferences.


Thermostats with geofencing capabilities use your phone to recognize whether you’re home or away. You can set the range of geofence, for example, to seven miles or 500 feet. Whenever you enter the set location, your thermostat switches to “Home” mode. When you go out of that range, it switches to “Away” mode to help you save money on heating and air-conditioning costs.

Diagnostic Features

A number of smart thermostats can detect when your HVAC system or ductwork has a problem. They may also provide you with your energy-consumption details and remind you when you need to perform maintenance, such as filter changes.

A smart thermostat gives you greater control over your HVAC system, which can lead to significant energy savings.
