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

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.
you can get an attic exhaust fan from Home Depot for less than $30 with a built in thermostat for hands free operation.
Attic fans with thermostat , the will cool the attic, you need two one on each side,
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.
