I wouldnt think it would save energy, or not enough to make it worth doing. It just seems like it increases the pressure to the open vents.

Well I try to keep vents closed that are not being used. I think in the long run this can help you save energy and money.
I have always thought that closing the vents would re-direct that cool or warm air to other rooms with vents open myself. My whole family has always done this. I hope its not an old wives tale.
This topic/question sounds like a good question to be answered by the MythBusters! Have you ever seen that show? Maybe we should submit this topic to them =D
Till then,

I may have to see if they have already one an episode on this one or if I should submit it as a show idea. Thanks for the suggestion. 🙂
You’re welcome! I am curious to see this myself, hehe =D If you don’t find it, be sure to plug you’re blog on your entry submission 😉

I think it such nice suggestion have given by used tires. You must consider on it.
Very very interesting! I too was raised with the idea that closing vents would help save some money and energy, but this actually opens a whole new can of worms to say the least!
I’ll be looking back here to see if you get any more info!
Usually, yes, but you must use common sense in selecting which registers to shut off. Rooms that have exposed plumbing or may have plumbing in the walls should be heated. You must also be careful about shutting doors.
In a 2003 study done by Lawrence Berkley Laboratory their findings were that if you close off registers closest to the air handler the loss is that you are using more energy than you would leaving them open. The study showed that if you close the registers farthest from the air handler you could save a minimal amonunt of energy. The study also warns that there is a fine line there because this can easily damage your equipment (crack the heat exchanger or freezing your evaporator coils) and from a safety stand point a crack in the heat exchange can kill an entire family. . .
