Heating and cooling adds up to about half of your home’s energy expenses. More and more homeowners across Southern New Hampshire and parts of Massachusetts are upgrading to WiFi thermostats. These attractive, user-friendly devices offer superior control over temperature and climate as well as automation. According to the EPA’s Energy Star program, an internet-connected thermostat saves up to $180 annually, paying for itself very quickly.
