Mobile Home re-duct-low airflow
Hello fellow HVACer's,
I think I'm in over my head on this one. I re-ducted a mobile home with flex duct to get better air flow to each room. It is much better, but not good enough. We installed a new Intertherm downflow unit and paid for the optional 5 ton fan set up. Static pressure went to .4 iwc!! Called Nordyne, they told us to lower the fan speed, basically back to 4 ton volume. Now it is .15 iwc, which is great but the air in the mobile is weak. We added booster fans to the trunk lines and it improved marginally. The owner is on the verge of demanding his money back. I have never failed a re-duct. How can I improve this situation? Who knows the most about mobile home systems? Any web-sites on the topic? I'm never touching a mobile home again
I posted this under GD and have had some good responses, but I am hoping to hear from someone that has had more experience with a M/H than myself.
