This compressor is not an inefficient compressor by design as it is used on nearly all ford models, Your compressor may be inefficient due to an internal problem with the compressor or an inaccurate charge, where as you have a low amount of refrigerant as a result of a previous repair and/or a leak in the system. Also some a/c charging machines will actually charge the system in your car with too much condensed vapors because the charge machine that was being used was too low on refrigerant to accurately charge with liquid refrigerant. I would need to have pressure hoses connected to the system while it is operating to monitor what the high and low sides are in relation to each other and the ambient air temperature and humidity play a huge roll in a/c performance, especially when it is not properly charged! I would advise that you locate a certified air conditioning specialist, who if trained properly will be able to pinpoint your problem upon evaluation of the system pressures!
