Attics need R30 insulation (at least) to keep heat out in summer and heat indoors in winter. In the long run, you can save money in both seasons by insulating your attic. Just make sure you get the right insulation; if it is not rated high enough or not thick enough it can allow the summer heat down into the house. If you have an attic, buy half inch plywood and lay it in between the trusses over the insulation. It will give you a walking/storage surface as well as enhancing your ability to block heat transfer. Insulation alone doesn't stop the heat from going into your house; it only delays the transfer until the attic cools at night when the heat flow slows down. Leaking windows and single pane glass let cold out and heat in. Consider Low E glass for window replacements and double or even triple-paned windows.. This will keep you cooler in summer by not letting the cold air warm up and warmer in the summer by not letting the hot air "leak" out. If there are any cracks or space between the windows and the walls, that's hot and cool air escaping like sands through an hourglass. Even if you don't upgrade your glass, make sure to cover any structural spots that need taken care of. There are a number of things you can do to your house that can keep it cool. Consider painting walls white or another really light color as light doesn't absorb a lot of heat like darker colors do. This goes for your roof, too – though a white roof may seem a little less than fashionable. You could also consider adding awnings or even extending the roof line so that the sun, in the summer, is blocked by the roof and is prevented from entering the windows. If the air conditioner is big enough to cool the whole house then air circulation is most likely the trouble. Hot air rises and cold air sinks. By replacing the register covers with register/fan units more cold air is forced out of the upstairs ducts. These units can be purchased at large hardware stores or home-centers. Try adding a couple of ceiling fans in the upstairs rooms or over a large open 2 story room such as a loft. Many fans have a switch that controls how it works – one blows air down and the other sucks air up. You want the fan to suck the cold air up and spread it over the house again.
