I picked up an old window unit off a 'free pile' on the curb last year that had a bb gun hole in the condensor, was able to hack it into a HP only unit using propane vs R22 (added a TXV off ebay vs the capillary tube), and works OK as a 1/2T equivalent unit out in the barn to just keep the chill off. Total cost about 50 cents worth of propane and $15 worth of brazing rod and Cu tubing.
