    Trane.

    I don't think cool has seen any of these mobil units. Weather by coleman, or miller(nordyne).

    I just hope he can get access to the website to find out what it is he's not familiar with.

    Your making it hard to be nice. Maybe you need a model number but some don't.

    okay if it is a mobile home unit and it is designed with a 12" supply and return how is it that he said that he was going to change it to 14" supply and return. i was under the impression that there was a supply and return plentum on the unit and coleman does make residential split systems.I have one in my house.just because it has a 12" supply and return does not mean that it is a mobile home unit.

    This is most certainly a package unit and the Original Posters thoughts are right on target.

    When you move the taps to the center,and a "sea gull wing" shaped diverter to the 10X5 duct to help turn the air.


    Adding the second return is smart, be sure the grille is large ,as well as the filters.If it's a floor return with a very open style "grille" size can be smaller.The box can extend down a couple of feet to allow a larger than grille sized return filter, at an angle in the deep box.

    The supply grilles should be changed to a larger size,like 10X6 ,that allow the air to blow stright up.Like a http://www.hartandcooley.com style # 210.


    The Coleman package unit is "higher" static,so if ducts are sized based on that ,it will be fine.

    Split systems for mobils use higher static blowers then regular residencials units. They are designed like that because of the ducts.

    ok now i understand the mobilehome unit with the 4 tn coil in it you can set the blower to the high speed and get 1190 cfms out of it with a static pressure of 0.5 and that is eough for the duct system with the 14 " supply and return.My bad i didnt know that but i do now thanks for pounding that into my head.I was under the impresion that it was a normal split system.
