How a Programmable Thermostat Helps You Save


With the price of a programmable thermostat not much more than a conventional dial thermostat, there’s no good reason not to upgrade. But when it comes to deciding which programmable thermostat to buy, as well as using the device correctly, there are a few things to keep in mind:

  • Programmable thermostats come in several different programming varieties. The most common options are 7-day models, 5+2 day models, and 5+1+1 models. The 7-day model allows you to set a different schedule for each day, which is nice if your home-and-away schedule changes daily. The 5+2 model is perfect if your Saturday and Sunday schedule is the same. The 5+1+1 model allows you to set a constant weekday schedule, but have a different schedule for Saturday and another for Sunday (or whatever days are your “weekend.”
  • Whichever model you choose, be sure to set the schedule and stick to it. This means that when you are home and awake, your setpoint for cooling should be no lower than 78 degrees, and when you are away from home or asleep, increase the temperature between four and 10 degrees. This will keep your home energy efficient and comfortable when you need it to be.
  • Use the “HOLD” option only when you will be away from the home for an extended period. Set the thermostat at your highest setpoint during the day, and hold it there.
  •  Avoid the temptation of overriding your settings and lowering the set temperature. Instead, use ceiling fans to create a wind-chill effect for room occupants, which will use much less energy and allow you to program the thermostat temperature a few degrees higher without any loss of comfort.
  • The ideal location for your thermostat is away from air vents and out of direct sunlight. This will avoid false readings and allow for consistent temperatures.

Jermaine did a fantastic job--he called to let me know he was on his way, was awfully nice, fixed the problem efficiently, and took the time to explain and show me how, where, and how often to replace the filters. Thank you!
