make sure you don't cover the condenser coils or cover the area of a skin condenser if the coils aren't readily visible.
Oh yeah, I meant condenser coils not evaporitive coils. Would a fan blowing across these coils help remove the heat and so reduce the overall power equation of the system? Maybe coulped with some cooling fins made of old aluminum scraps. Man, now I wish I had one of the kill-o-watt thingies and a fridge on which to experiment.
