Smart and programmable thermostats can save money by raising the air conditioning temperature when you’re away and overnight. Whether you want a different setting for weekdays and weekends, or to schedule each day of the week, there’s a model for every lifestyle. Set your thermostat to 78 F, then program it to raise the temperature 8 degrees when you’re away from home and 4 degrees overnight. Check outdoor temperatures and open windows overnight to cool your home for free. The only difference you’ll notice is lower cooling bills.
