My house has just gable vents.I installed soffit vents to improve ventalation but then at night when I open doors the house gets warmer like the attic air is coming down in the house.I then was told to install roof vents and close off the gable vents.
I have had times where outside it is 65 degrees and if I open doors/windows house temp will rise instead of fall.
This makes no sense to me.
