Since they are electronic, programmable thermostats are more accurate and efficient than thermostats that contain mercury. With programmable thermostats you can control the temperature in your home at different times of day without ever touching your thermostat. Because everything is automatic, you will never forget to change the setting on your own.
We added on to our home and I upgraded my entire heating and air system and ductwork as recommended by the comfort specialist and our power bill went down! We have never been this comfortable in our home since we bought this house! Thanks Jimmy and the whole Wilson's crew.
