Also the hole you make for the housing should be completely covered by the grill when completed so there should be no need for sheetrock repair. The bad news is you may run into a problem removing the old fan if you do not have access from above. Usually the fans are nailed to the joist before the ceiling goes up. You will not have easy access to the nails from below it.
Your best bet may be to push up on the old housing so that the edge of the housing away from the joist is above the sheetrock and then try prying it off the joist. Just guessing though since I'm not there. And make sure you vent it to the outside! Last edited: May 5, Does the trim ring mount in such a way that it would "cover" the part of the flange below the ceiling. If that is the case, just use an inbetween dimension and put it flush with the sheetrock.

If so, did the old fan system have a damper somewhere else in the air duct, like at the vent hood at the very end where it comes out of the outside wall? If so, then your poor little fan has to open TWO dampers.
In that case, get rid of one of them. Is the vent pipe too long or has too many bends in it? If not then you again may have to just live with it. Is there a proper vent pipe at all? Some unscrupulous types will just dump the air into the attic area and there may be an obstruction or insulation blocking the air flow.
Do you have proper "make up" air flow coming into the bathroom? A common mistake is that people have no grill on the door and then have thick carpet coming right up to the door, so that air cannot get through the crack in the bottom.
When a vent fan pulls air OUT of the room, air from the rest of the house must be able to get back IN to make up for it, those little fans can't pull a vacuum. So if there is no way for the air to get into that bathroom, or even in extreme cases the house is sealed up so tight that NO air gets in ANYWHERE, the fan has to struggle to get anything moving. Improve this answer. JRaef JRaef I tried starting the fan with the cover off, and the fan mechanism doesn't move at all for a couple of seconds after the power is applied.
After a few seconds it starts to spin slowly and ramp up. To answer your other questions, this was a retrofit, and when I looked in the attic, the flexible vent pipe seemed too long. There's a couple feet laying on the attic insulation and at least one bend before it goes up to the vent. I don't know if there's another damper on the exterior vent hood since it's on the roof , but the original ones on the side of my house seem to have dampers. There's plenty of make up air, since it does this when the door is totally open.
I just installed one of these. With the cover off I watched the fan after flipping the switch. There is no movement at all for about 10 seconds, and then it starts to ramp up.
