Have you ever forgotten to turn off your HVAC system when you're the last one to leave the house? Julianna from St Cyril & Methodius made sure her home's thermostat was properly programmed so that's never an issue. Why heat (or cool) your home when no one's home? Additionally, programmable thermostats can pre-heat or pre-cool a home in the hour before you get out of bed, or come home from work saving additional dollars. She knows that raising your thermostat five degrees in the summer can save one percent overall on your annual electric bill! Way to go!
