I have a quick question. I am in the process of building a new home and the house is going to be sprayed with spray foam and they are going to do the garage for me. I was thinking of maybe having 2 vents run there, keeping them closed except if I had some work to do in the garage I could have the AC or heat blowing in.
My question is if I have 2 vents and close them obviously they still leak but does the rest of the first floor suffer because of having the vents there. Thanks for help.
