Let’s Settle This: Open or Closed? Part 1

My husband keeps closing the vents of the rooms we aren't using. Is this helping keep our main living rooms warm? I mean, really all it's doing is kind of causing damage to the system itself. Trying to force more air to a specific area that you're using more commonly, that could help a little, but ultimately it's just going to cause issues down the road. You're really not making a difference to any of those areas. It actually slows down because that pressure has built up against it. I can wear down on the motor, the compressor outside, expansion valve. Those things can only withstand so much.
