My wife and I moved into a new house last summer. When we first saw the house in the spring, we did not notice that the third floor master suite had only one vent and had poor ventilation. It is very hot in the summer and cold in the winter. This is the only room in the house that has this issue. We have been using supplemental heating and cooling apparatuses to keep us comfortable and installed an attic fan to help, but nothing seems to really work all that well. Looking for a more permanent solution to this problem, but on a budget.
