Have a shop pump out the freon, then just remove everything related to the a/c. Compressor, hoses, brackets. You'll probably have to get a shorter belt to replace the one you take out. The evaporator coil is in the heater box under the dash and would probably be a pain in the butt to remove, so just take out the hoses to the firewall. Your biggest gain will be the weight loss. The pulley uses nothing unless the a/c is actually on.
