Cool air could escape from your home this summer through two spaces you probably don’t pay much attention to: the attic and the crawl space under the home.
If your attic doesn’t have enough insulation it could let cool air out and hot, summer air in. Even though your home was probably built with plenty of insulation, it can thin out and fall away as time passes. Poke your head into the attic and look: Do you see bare spots on the attic ceiling or floor? If so, consider having some more insulation installed.
The same goes for spaces below grade, like a crawl space or a basement. When that space is poorly insulated, it can make the floors on your main living level feel cold and can cause uneven temperatures in your rooms.
Have a contractor take a look. You could need more insulation in rim joists, the basement or the crawl space.
