In this instructional video, Derek Cole explains why one side of a mobile or manufactured home may experience a complete loss of airflow. He outlines several potential causes—clogged air filters, blower issues, and especially problems with the ductwork. The focus is on the crossover duct that connects the two parallel duct tracks common in double‑wide homes. Cole describes how the crossover can become blocked, fall, or be damaged (often by animals), leading to one side not receiving conditioned air while the other side functions normally. He notes that the duct system is prefabricated and generally inaccessible, but the crossover is reachable for inspection. He advises homeowners to first check the crossover for damage or blockage, replace dirty filters, and consider blower problems, but ultimately recommends calling a professional due to the complexity and his extensive experience with mobile homes.

One side of the mobile home, my mobile home, is not getting any air. So what's going on? Um, believe it or not, we've gotten these calls, calls fairly common. Um, so you know, it could be a number of issues. It could be a clogged air filter. My notes say issues with the blower, like your ductwork. Blocked or fallen ductwork is the one I want to focus on because that is the biggest problem I've seen over the years. Um, so if you have a mobile home— and it's more common in, in double wides or, or, or bigger mobile homes than a single wide— but the double wide has, if you're kind of looking at it from, from Google If you look down on the mobile home, you know, it's kind of a rectangle shape. You have two tracks of ductwork. You have one on one side, one on the other side. Well, they're connected by what's called a crossover duct. We have seen so many situations in which that crossover duct has been either down, damaged, It could be damaged by an animal under house, um, but usually the culprit is that crossover duct. Not— it's connecting those two tracks to the air, so that's how you get one side not cooling and the other side is cooling. So blocked or fallen ductwork or crossover duct, uh, is usually the main culprit. Now Uh, with the mobile home, any manufactured home, the duct system is manufactured as a part of the house. So you have, like I said, what, again, two tracks of ductwork which are already prefabbed, pre-made. We can't get to it, but we can get to the crossover that connects both tracks. So that's something to look at. Uh, first is to make sure the crossover is not a problem. Um, you might have had an animal or a raccoon or a, you know, a cat, uh, get under there and then might tore it up and, uh, caused some damage there. So a damaged or fallen duct is usually the problem, but it can also be a blower problem. Um, the air filter just needs to be changed. Airflow is not good. Uh, it could be those couple things, but the most common one I've seen is the crossover duct being the problem. So double-check that. If you have any questions, call a professional. Please get a pro out there, uh, to see what's going on with this system. We have done so many mobile homes and do so many mobile homes. Uh, we have a lot of experience with mobile homes. And we've seen a lot of situations in which things are not attacked correctly or even explained correctly. So if you have any questions, we would love to help.
