I have a bathroom that is roughly 5' by 5'. I have a vent w/light unit, which I beleive it quite big enough to vent this samll space. However, I have drip lines on my walls as if you threw water on them! Also some paint bubbling effects on the ceiling near vent are, and drywall tape coming loose. UGH...
Every know and then I get a rooster sound effect from it. I then go up and clean the vent/fan and spray with wd-40 and it ceases the noise.
The vent has a dryer hose secured to it, which goes into attic and up very near the attic fan to vent out. Should I buy a new vent? HELP!!
