Programmable thermostats can save you an estimated 10-20% on your heating and cooling bills. When you aren’t home, or are sleeping, you can set your programmable thermostat to a lower/higher temperature. It will then heat/cool up your home just before you wake up or get home.
We love the house to be cooler when we are sleeping but waking up to a cold house isn't fun. The same goes in the summer when were out why waste the A/C when no one is around to enjoy it.
A programmable thermostat can also help you be green all the way around. Did you know that heating and cooling alone take up about 49% of all household energy use. That’s almost half your energy bill! Compared to a fixed thermostat, programmable thermostats changes the temperature on a set schedule. This helps to reduce how much money and energy you use. Using a programmable thermostat the average person can stop about 22,000 pounds of CO2 emissions per year! That’s like taking 2 cars off the road.
