ABSTRACT:
A device for use in lifting an air conditioning compressor from an air conditioning unit for servicing or replacement of the compressor. The lifting device is also useful for setting a replacement compressor back into place in an air conditioning unit. It simplifies the task of lifting the compressor by allowing the lifting to be performed at a height that reduces risk of bodily injury and thereby allows the task to be more easily performed. The device is usable by either a single person or by two people if the weight of the particular compressor calls for two people.
