David writes from Kaneohe, Hawaii: "I own a condo in Hawaii that is not insulated. I have to run the A/C constantly to keep it cool. The ceiling is enclosed without any means to access the 24 inches of dead air space between my ceiling and the floor of the unit above me. Can holes be drilled in the ceiling and insulation blown into the dead air space? I have tried to find a contractor in Hawaii that could do this but I have hit a brick wall, no one here blows in insulation. Home Depot doesn't have the equipment to rent to do it as a weekend project. Do you know of anyone in Hawaii that blows in insulation?"

Answer: If there is a unit above your condo you probably won't experience a noticeable thermal benefit from ceiling insulation. Depending on the structure, there may be some acoustic or sound control benefits. If the exterior walls are not insulated, you could expect some thermal benefit if you can insulate them.

You may be doing this already but you should make sure you are following good thermal management practices, such as blocking direct sunlight with curtains, blinds or draperies; turning off unneeded lights; and making sure the doors and windows are closed as the outside air begins to warm up.
