I arrived for a new customer airflow problem in a double wide trailer home. I spoke with the homeowner and found that the front of the home is not getting airflow like the back of the house is. I inspected the system and found the system to be a 4 ton set up with a 10” bypass duct to the other side of the house. The system is running well but the small transition duct is not allowing airflow to the other side of the home. We discussed the system and how to properly maintain the system and we decided to sign up on our red club membership plan. We also decided to purchase a video inspection on the duct work to confirm that the duct work is cleanable for the red club maintenance plan and to see if there are any other issues with the interior duct work. If the scoping comes back good we can go through with increasing the transition duct from a 10” to a 16” metal duct. This is as far as we can go before we will recommend to have a noble home company come out to repair or replace the duct wo
