Heating and cooling make up the bulk of residential energy expenditures, so why not invest in a smart thermostat? It’s is an easy, cost-effective way to reduce the carbon footprint of any home.

ecobee smart thermostats are Wi-Fi compatible, meaning they think so you don’t have to—sensing if anyone is home, locating hot and cold spots, even making micro-adjustments to account for changing weather.

All of this means targeted technology, so an ecobee thermostat provides heat where needed and doesn’t waste energy by heating unused or empty parts of the house.

And the newer ecobee models are voice-activated. They can be controlled via Wi-Fi voice interfaces like Alexa. They’re also slim and sleek and a good bit better looking than your current thermostat. And at a cost of $249 for the latest iteration (ecobee 4), they pay for themselves in about a year. Certain models may also qualify for energy-savings rebates. See ecobee to find out more.
