10. I hate to have to disagree with some of the advice you are getting. There is no simple answer.

In the end, it depends on your home, its age, the system, ductwork, etc.

It could very well be a bad thing to close ducts. In my town the utility company gives classes to contractors and educational tours to customers.

I was told not to shut off rooms because it can mess with the balance of pressures and have negative impacts. They had a plexiglass model house to with fans and smoke to illustrated the concepts.

You might check with your utility company to see if they'll come out to visit your house.

If you have central air conditioning, do not close vents in unused rooms. This could increase pressure and cause leaks in your ducts. This does not apply to homes or apartments with window units, where closing off unused rooms will reduce cooling costs and increase comfort.
