Dampers are valves or plates which stop or regulate the air flow inside a chimney, duct, air handler, VAV box or other similar equipment. They could be used in cutting off central heating or cooling to the unused room or in regulating the temperature in each area. Its operation may be automatic or manual which is turned using a handle outside of it.
Automatic ones are controlled based on different factors which include temperature so they can be closed or opened as necessary.

Installing it yourself is possible as long as you know the necessary steps in doing so.
