Not too sure what the question is. If your weather is very dry, you may not get very much water out of the air, and what little comes out could evaporate, but under most conditions there should be some water (condensate) coming from the unit when it is on. Is there a visible drain hose from it on the outside? You may need to see if it is plugged up. If you can get it open to inspect it, push a wire or something up through the drain to see if you can open up anything that is clogging it. If it is plugged and water builds up in it, you are going to have problems.
