Hi all,
I wil be installing a 3.5 ton evaporator airhandler in a ranch home and am curious on how far I can run thr the main trunk. The house is rather long at 90 ft. I thought the best way would be to use a pair of pants off the supply and split the main trunk in two directions with the trunks instead of one long run. I am not sure if the blower at meduim speed(factory preset 1640 cfm) will be sufficient for such a long run or if I should change it to high. It would be roughly a 50 ft run if I ran it straight. I would reduce the trunk as it went naturally to accomadate the required cfm. Does anyone have an opinion on a run that long or is spliting it better.
Thanks in advance.
