We live in the top two floors of an old brownstone in NYC. It gets CRAZY hot on our top floor, which is really the attic of the house, but where we have our three bedrooms and one bath. It's also poorly insulated. The front two rooms have dormer windows and the back bedroom and bathroom have only skylights. There is also one window on one side of the house (the wall on the other side is against neighboring building's wall).
We are very low on cash or I would install a mini-split system. Researching whole house fans, they seem like a great option for us, but I can't figure out how we could do this if we live in our attic. Also our stairwells from 2nd to 3rd and 3rd to 4th floors are pretty open.
The ground floor and 2nd floor of the building have separate studio apartments; we have our door on the 2nd floor landing, so the landing is also part of our living space.
I hope someone has an idea, I can't find anything about this on the web!
