My house has a bedroom and bathroom in the finished attic. We had our first rather warm day here since I bought the place and I can tell that it's going to be HOT up there. There is one vent for the HVAC system in the bedroom, and it's not a huge space. What steps can I take to make it as cool as possible up there in the warmer months? There is a small unfinished space in the attic, with a single vent at the front of the house.
