I have two Kenmore window AC units that I was always wondering why the design was made such that some of the condensed water was always left in the bottom, so that the fan blades hit the water and splash it to the condenser coil. Now I know the reason! It does provide the same effect than cool-n-save does for the central AC compressor...
The AC unit has a drain hole on the back which is plugged with a rubber plug. I thought it was stupid to keep water in there and removed the plugs... Now I'm putting them back.
I measured the input power of the AC unit by using Kill-a-watt power meter. I can see about 10% power decrease after plugging the hole.
With this in place now the AC can maybe live up to its 10.8 EER rating...
