is this for real? if so might have to try during winter...
our duct runs 9' to the ceiling then through the floor cavity for like 30 F-ing feet.... takes 3 cycles to get dry
Plus during winter we would have some nice fresh smelling heat lol
Based on the original post, Id guess the vent at the end is clogged with lint at the screen like others said... Im sure mine is as well, but cant figure out which one is mine at the apartment without a ladder (maintainance is useless)
