How to cool attic -in cape code home-we have two rooms and no central airconditioning?

You dont need an air conditioner for the attic. If you go to HD or Lowes you can get an attic fan which costs $90 and would be much cheaper to run. Putting an air conditioner in the attic would cause problems any way. Central air does not get directed into the attic, just the house, so that wont help your situation. Also dont forget if you air condition the attic then you are looking at some major moisture problems in the summer which is probably what you are trying to avoid. This in turn would warp the flooring and possibly ceiling below. Also it would cause mold problems from drastic temperature change.

Mine does. It has a thermostat that automatically turns the fan on when the temp in the attic reaches 90 degrees. Since my AC is set to go on when the temp in the house goes over 80 degrees you would think that the attic fan would be of no help. Wrong! The attic sometimes reaches 90 degrees by 11 AM and the house doesn't get up the 80 degrees until 1-2 PM. The attic fan moves the hot air out of the attic and keeps the AC from turning on until 3-4 PM. The attic fan costs 2 cents an hour to operate in my area and the AC is 80 cents. My neighbor has exactly the same model home that I do without an attic fan. Her AC is set to exactly the same temp and turns on around noon. She is running her air a 4-5 hours longer a day than I do. The fan in the attic is not only a great savings on the electric bill, but also really does keep the house cooler in my experience.

you can get an attic exhaust fan from Home Depot for less than $30 with a built in thermostat for hands free operation.

The least expensive way to cool it down is by buying some of those big window fans. It takes waaaaaaaay less electricity to run them and it will still cool it down nicely.

Those are all good ideas, but more insulation will also help. And on hot days, keep all the blinds closed, also reflecting window tinting works well.
