Today I arrived on site to perform a visual inspection. **AC System Inspection:**Identified uninsulated ductwork. Upon arriving at the property, the client directed me and explained to me about some samples of organic growth inside a stop in one of the rooms on the 2nd floor. I proceeded to make a visual inspection of the situation. I found that behind that wall that the client mentions there is a duct without insulation. I explained to the client that it is very possible that in summer when they run the Ac system this duct cools and begins to sweat, causing a wet space inside the wall. The client mentioned that she would like to insulate this duct to improve the humidity situation inside the wall. Office to follow the client for a consultation to isolate a duct that is sweating. Notes: I suggested the client to make an appointment with John S. To verify and provide an estimate to the client to insulate this duct. The client also mentioned that she would like to know any suggestions
