If your window unit AC unit is working hard and not dripping outside, adding a little water to the condenser pan will help cool the high-pressure liquid line that collects refrigerant and holds it until the metering device opens and turns it into a low-pressure low-temperature gas. The colder the gas in the evaporator the more heat it can absorb. If you are in a dry climate your unit may not have any humidity to help it out. The evaporator wrings out your living space air and trickles that moisture through a tiny hole in the styrofoam jacket that separates the inside air from the outside. If that hole blocks up, your fan spits water into the room and then that water can't get outside to collect at the bottom of the condenser pan. Squirting a little water on the condenser surface (don't force water into the fan!!) will cool it down and water will cover the copper line under the coil, adding efficiency. This is called sub-cooling. I've never seen a modern AC window unit low on refrigerant. They don't usually have a receiver to collect the cooled high-pressure refrigerant liquid, just a precise amount of "freon". If the condenser or evaporator is dirty or the fins are blocked, clean it and straighten the fins. It will make a difference. Then adding water to the pan outside just ensures the tiny amount of refrigerant isn't flashing into a gas after it leaves the condenser. If that is happening it won't cool well. So try the steps I have in my Playlist called "Air Conditioning" and get a little extra cooling on these 100-degree days. Thanks for watching, and reading this.
