When you make ice in the freezer you do it by transferring heat from the water through the condenser in back of the fridge to the ambient air. You are paying the electricity to freeze the water, then paying the electricity to melt the ice by removing the heat from the air that you paid the electricity to put in the air in the first place. Absolutely zero delta heat in the home. At least a window air conditioner sends the heat outdoors and you actually get net cooling in the home.
