If you’ve already hauled out the extra blankets and pulled sweaters from storage, you’re probably thinking carefully about how much you use your home heating system. Smart thermostats can help keep indoor temperatures comfortable while reducing energy waste. Models from brands such as ecobee, Sensi, and Google use accurate sensors to adjust furnaces, boilers, heat pumps, and other HVAC systems for better efficiency. They are generally simple to set up and can begin lowering energy use as soon as they are installed.
PCMag has evaluated every major smart thermostat with its standard testing process, including hands-on use with home HVAC systems. Each product is scored on efficiency, installation simplicity, and notable features. If you are looking to save on your first energy bill, these current discounts on five well-regarded smart thermostats are worth a look.
