The HVAC system of Charlotte area homes run pretty much year-round, so add-ons that can increase their energy efficiency are welcome. Once such upgrade is a programmable thermostat, but they can only contribute to savings if used correctly.

How They Work

Programmable thermostats allow you to set the parameters of your central HVAC system’s operation according to usage patterns. You’ll need the house warmer when you wake up, for instance, than when you’re asleep or out all day at work or school. A programmable thermostat allows you to save money during the low-traffic times, without constantly adjusting the settings manually.


Correct use begins with an optimal installation location. Choose an interior wall, at a site remote from drafts, direct sunlight and bright lamps, heating and cooling vents and other sources of non-typical temperature readings.

Proper Usage

To maximize the savings possible with programmable thermostats, consider the following:

  • The temperature set points should be calibrated for at least eight hours. For most of us, that conveniently divides the day into the period when no one’s home, when the house is being actively used and when most residents are asleep.
  • Don’t use the override function to ramp up temperatures more than necessary.
  • Remember to use the “vacation” feature when going away, even for a long weekend. This keeps the temperature safe without reaching the comfortable norms you set for occupation.
  • Wild swings in temperature increase energy usage. Don’t set the unit to it’s extremes when overriding. It won’t heat or cool your house any faster.
