How do you get to the air conditioner on Game Show Island?

You don't. You have to go to the factory and use the crane to get to the middle platform. Go to the left, click on the computer. Then go to the top platform, and on the right is the main power. Use your toolkit to unscrew the screws, and click on the very top left switch. You have started the conveyor belt, and in return you will get a fan. Use the fan to cool off the club owner. He will give you a nickel. Go back to the factory area and give the man on the far left your nickel. He will give you heat detection goggles. Use them at the club. Once you detect something (the inventor going up the A.C. shaft) go outside and use the fan to get up to the window, and use the toolkit to unbolt the window. Then you chase the inventor down.
