so by opening the HOT air in the basement it will lower the temp rise ? How does that work ?
I will open it I usually have it closed in the summer for the AC but I open it in the winter for the extra heat. It is in the celeing so I dont get alot but I do get some heat from it.
Thanks beenthere for yor help just explain how it will lower it and how bad it is to run my furnace at the higher rise number.
Is it an easy fix for the installers to lower the temp rise or do YOU feel its unnessasary ?
