Abstract: The invention relates to a method of cleaning the condenser coil subassembly of an air conditioning apparatus and a bag apparatus for achieving that result. The invention envisions placing a flexible bag construction over and generally around such subassembly, but not over or around the subassembly containing the other components of the air conditioner. This bag has an adjustable mouth portion that will fit over the condenser coil subassembly and also has respective hole means to allow the entry of compressed air and exit of vacuum air, respectively, to and from the enclosed area surrounding the condenser coil subassembly. When the bag is appropriately in place over the subassembly to be cleaned, compressed air is supplied to the enclosed area to loosen and remove debris from the coils while vacuum air is also supplied to remove the debris from the enclosed area to thereby resulting in a cleaning of the condenser coil subassembly without contaminating the area outside the bag.
