My AC emits a unfamiliar smell, AC drain tube is leaking, and making noises

Hello! Sounds like you have a couple of different things occurring. I would guess that your drain tube is plugged, causing the evaporator to overflow inside the interior. This could be causing noise from the system if there is water built up inside. The smell could be because of bacteria in the system from moisture build up. However, it could also be something else!
