My husband and I are buying a home which was originally a basement home and then two floors were added on. The top floor has two very large bedrooms with a bath in between. We have learned that the top floor bedrooms get very hot in the summer and very cold in the winter. The insulation seems to be in good shape. What can we do to make the temperatures more even throughout the home?
P.S. The house has a new roof, furnace, siding and windows.
