Green Tip: Go digital—thermostats, that is.
How many times have you left the house for the day and forgotten to turn down the heat or AC before you left, letting it run you financially amok? By swapping out your old school thermostat for a digital thermostat, you can program your system to automatically regulate to the temperature you set for different times of the day and each day of the week. You can pick one up at Home Depot or Lowe’s for about $35. Money well spent, and saved.
