came out because the customer was concerned about his unit having issues because water had gotten into his air ducts. After diagnosing the system. I found that that two ducts were compromised. One in the main floors bathroom and one in the room that shares the wall with the bathroom. We will meet to replace one 8” duct and one 6” duct. I would also like to add UV protection to prevent any biological growth building up in the system and i’d also like to get the customers signed up on a regular maintenance plan. The system itself is running according to specifications. The customer was also concerned about a loud noise coming from a the return in his guest bedroom. Ii took a look in the attic and found that the 10” duct run was way to short causing that loud noise as the air is moving through that duct to quickly. We will need to replace that duct as well.
