More About Backdraft Dampers

A damper, or backdraft damper is an absolutely essential yet often overlooked piece of HVAC equipment that seriously helps to keep your home at the temperature it is supposed to be at. Without going into too many details, the job and function of a backdraft damper is to keep air flowing in a single direction, typically out of your house. They allow for your HVAC system to vent air to the outside without letting hot air in in the summer and cold air in during the winter which would wreak havoc on your HVAC system and on your energy bills. These dampers are built tough and will last a long time as an integral and energy efficient part of your total HVAC system. If you think that your energy bills are too high, especially in the winter, then you may want to look into adding a new set of backdraft dampers to your home system.
