Emerson Sensi Smart Thermostat is one of the most-loved smart thermostats on the market today. The thermostat features a responsive touchscreen and a user-friendly interface and intuitive app that require no special experience to use.

The Sensi app lets you adjust your home’s temperature on-the-go and it provides you with usage reports and energy saving tips. Installation of the Sensi could not be easier.

Most installs of the Sensi thermostat take 30 minutes or less, even if you have never installed a thermostat before.

Google, T3007ES, Nest Learning Thermostat

Google’s Nest Learning Thermostat is a remarkably intelligent device packed full of useful features.  This smart thermostat actually learns your temperature preferences and will automatically adjust itself based upon those preferences.

The thermostat also connects to your phone and adjusts the temperature after you leave, so you don’t end up heating or cooling an empty home.  This learning ability can result in you saving a good chunk of cash on your monthly energy bill. In fact, according to Nest, Independent studies have proven that the Nest Learning Thermostat saved an average of 10% to 12% on heating bills and 15% on cooling bills. Therefore, this smart thermostat has been shown to end up paying for itself – who could hate on that?

Nest comes equipped with a ton of other useful skills and features. Your temperature can be controlled by any internet-connected device, whether it is your phone, tablet, computer, and even your smart assistant such as Alexa. When Nest spots you across the room, its “Farsight” feature causes the thermostat to light up and show you the time, temperature, or weather. Nest also provides you with reports on your energy history and provides insights on way to save energy.

Honeywell TH9320WF5003 Wi-Fi Touch Screen Programmable Thermostat

Honeywell has been a major producer of thermostats for many years – and they are still making them today for good reason. Over the years, Honeywell has consistently produced top-quality thermostats, so it is no surprise that their Wi-Fi Thermostat is so popular.

This smart thermostat is one of the few that gives users the ability to change the color of the screen, making it that much easier to incorporate a thermostat into your home’s décor. The display is larger than most smart thermostats on the market today so it is especially good for people who have a hard time reading small print. Because the touchscreen is so large, it also incorporates a good bit of information aside from internal temperature, such as the time, date, outdoor temperature and humidity levels. It even offers a trilingual display and supports both metric and customary temperature readouts.

As for accessibility, the Total Connect Comfort app allows you to remotely manage your home’s energy use from your phone. The thermostat requires professional installation but it also comes with a 5-year warranty. 

What to look for in a smart thermostat

When shopping for a smart thermostat, assess the following features:

  • Installation (professional versus DIY)
  • Ease of set-up and programming
  • Programming type (geofencing or manual scheduling)
  • Learning capabilities
  • Easy-to-use mobile app
  • Compatibility with a smart assistant (i.e. Alexa)
  • Warranty length
  • Does it require a C-wire?


Q: Are smart thermostats worth the money?

A: If you purchase a smart thermostat, it will likely pay for itself over time and possibly in as little as one heating and cooling season. On average, most people recoup the money spent on their thermostat in under 2 years. 

Q: Are smart thermostats hard to install?

A: Most smart thermostats take less than 30 minutes to install and you can install them by yourself with no experience required. However, some do call for professional installation. Make sure you read about the smart thermostat’s install before purchasing.

Q: What is a C-wire?

A: The C-wire supplies your smart thermostat with 24V of electricity. Smart thermostats use more power than regular thermostats, so most WiFi thermostats will require a C-wire. Read the install requirements to identify whether a smart thermostat requires a C-wire before purchasing.


If you are ready to start saving money on your energy bills, then it’s time to upgrade to a smart thermostat. Just make sure you determine all the features you want to have in your thermostat and make use of our tips.
