I didn’t grow up around HVAC professionals, nor was I one of them. As a child, I remember a common practice was people closing air vents in unused rooms to save money on their electric bill (or gas bill). This always seemed to make sense to me from a common sense perspective. But, does closing off the vents in unused rooms actually help save energy and money? Can closing the vents actually cause problems with the HVAC unit?
In this post I will be answering these questions along with other related questions!
Let’s get to the first question….
Does Closing Vents in Unused Rooms Save Money?
In short, no. Closing air vents in unused rooms actually does not save energy or money. Yes, by closing a vent, air is no longer distributed to that specific area, but that’s likely not what your installed system was designed to do.
