If you have unused rooms in your house, how can you save money on central air conditioning?

  1. Close the air conditioner registers in the unused rooms and close the doors
  2. Open the windows in unused rooms to increase air circulation
  3. Add window air conditioners to the unused rooms, and run them only when the room is occupied
  4. Keep registers open in the unused room, and use a programmable thermostat to set back air conditioning at night or when no one is in the house

The best way to save energy is to use less air conditioning throughout the home.

If you didn't get the correct answer, don't feel like you are all alone. Most people commonly close the register and close the door on unused rooms thinking they will save money by not cooling that particular room. However, it's not the best idea. When you seal off a room's AC register(s), it creates extra pressure on your air conditioning system. This can lead to air leak through your duck work which is actually worse in the long run. 

A study by the Lawrence Berkeley National Laboratory proved that closing registers in unused rooms actually increased energy use throughout the home. Plus rooms that stay warm with no air flow is a breeding ground for mold and mildew.[/expand]
