If you're interested in upgrading to a smart thermostat, you're either probably tired of manually setting a basic analog model or want to improve upon the features of your digital or programmable thermostat. 

A unique feature of a smart thermostat is the ability for you to remotely control your HVAC system through any Internet-connected device, including mobile. This gives you total control of your heating and cooling, resulting in greater energy savings. Like a programmable thermostat, a smart model can help you realize a savings of between 10 and 20 percent in energy costs. It's also a great choice for the homeowner who doesn't feel comfortable with their ability to correctly program their thermostat. In addition, the setup time for a smart model is quick and easy.

Depending on your needs and budget, there's sure to be a smart thermostat right for you. Priced at $119 on Amazon, the Honeywell Lyric T5 Wi-Fi model features a user-friendly touchscreen. Also easy to use, the Emerson Sensi Touch Wi-Fi thermostat is available for $133 on Amazon. Another great buy is the Nest Thermostat E that sells for $169 at Best Buy. One drawback of this model is it might not be compatible with some high-end HVAC systems. Priced at $229 on Amazon, the Ecobee4 Alexa-enabled thermostat with sensor lets you place sensors in whichever rooms you need the most comfort and is compatible with most other home smart devices.
