Clean the coils, inside and out. I can usually get at least a one amp drop by cleaning the outside coils, often two or three amps.
Chris warned me about something else when our Coleman Mach 15 was drawing high amps and shutting compressor off from its internal overload cutoff. The "outdoor" coil (at the rear of the unit, properly called Condenser) will overheat if the hot air it's trying to get rid of, is "short cycled" back into the coil. The edges of the Condenser should have foam rubber baffles to keep this from happening. Ours were missing. I improvised with pieces of foam "swim noodles" and it's been OK since.
So when you're up there cleaning, be sure there are seals in place. Cheap to make if they aren't.
