My dryer vent dischare is right beside my AC Unit. I can't move the AC and the dryer is against an outside wall and the only other direction I can run it is into the garage. Is my only alterntive to run a a pipe from the existing vent exiting my house to get the discaharge lint away form the AC coils? I'm reallytrying not to run a 4 inche pipe on the outside of the house to get the lint away from the AC, but what else can I do?
