One of the best ways to quickly cool down a room is to install a window A/C unit. This will effectively cool down the room by working to condition the air in that space only.

You can pick up a dehumidifier at any home improvement store.  Dehumidifiers aren’t cheap, but they are usually portable, so you can bring it from room to room to maximize its usage.

If you are using window curtains or drapes, get medium-colored ones with white plastic backing to efficiently block heat. Be sure to hang them as close to the window as possible. Shades are also very effective at keeping heat out – be sure to mount these as close to the window glass as you can to create a sealed space to trap heat.
