My husband remodeled our bathroom and did not vent the ceiling fan outside , he left it just hanging out in the attic. Now the fan will not take moisture out of the bathroom. It has to be vented outside in order to work properly right?? Thanks

It needs to be vented outside to meet building codes and prevent moisture and rot in your attic.

The problem is more than likely the adapter on the fan. Every exhaust fan includes an adapter that converts a square opening to the round exhaust duct. This adapter attaches directly to the exhaust fan and then the round duct attaches to it. This is probably installed upside down.

In this adapter, there is a flapper that prevents air from coming back into the bathroom. When the exhaust fan runs, the airflow pushes the flapper open and allows the air to exhaust. If installed upside down, the air will not be removed.

Yes it does. If you vent it into the attic you are asking for moisture problems, potentially causing rot, mold, damage to your insulation and ceilings. He can vent it to an outside wall if he doesn't want to deal with the roof. As far as the fan not moving air, there is probably an obstruction in what little duct work he put in.

If the fan is determined to be working, you should consider the following. Building codes require fans to vent to the exterior. If you live in a warm climate where it rarely drops below freezing you may be OK with venting to the attic if the attic is properly vented. In a very cold climate your are inviting major problems.

bathroom fans are required to be vented outside, they get vented to attics by do it yourselfers who have no idea. (no offense) If you want to determine if the fan is exhausting air, use smoke. A cigarette, a smoking piece of paper. It will not recycle all the air in the bathroom, foggy mirrors after a shower are still possible. Especially if the installed fan is not big enough. The more cfm's the fan is, the more air it will move.

Seek the advice of someone at home depot or some other home improvement store. Send an email to hgtv.com and diy.net for more info. You may need to send a digital photo but as long as you describe the problem in enough detail, you should be able to get advice.

If does sound like you need to vent it to the outside since the moisture could create mold, etc.

Not at all. Most fans are vented directly into the attic. Odds are good the flap may have been installed upside down as it "seems" that's the way they should attach or it's stuck in the closed position. Odd design. Remove the motor and poke the flap with your finger. Hopefully it's just stuck and this will take care of it. Otherwise, you'll have to go into the attic to fix it.

Annabelle Annabelle take it easy on your man darling. I can't believe he installed a fan without bracing it securely...From what you presented, I am a little stumped. The humidity from steam in your bathroom is being drawn into your attic. Right so far?..This is what the bathroom exhaust fan is supposed to do. Draw the humidity out of the room. No, the bathroom exhaust fan does not have to be vented outside to work. Go into your bathroom and close the door. Turn on the hot water and let the shower run so that your bathroom mirror steams up. Shut off the water and turn on the new exhaust fan. Let it run for 5 minutes or so and see if it removes the steam. Now go and apologize to your man for doubting his carpentry skills, but do ask him to double check the way the fan is braced. A loose installation will develop a rattle over time.

Your fan imight be out of balance, most fans come with small round weights that are sticky on one side. You attach these to the unseen side of a fan blade. This should fix the problem, if not the blades might be loose, just tighten them up.

not all fans need to be vented but they need to be installed right , perhaps you have the wroung fan you mite have a blower fan that really just pushes the air around, ?
you need an extractor fan one that pull the air out of the room . and most attics can take the air, not a problem .

at least he tryed eh? good for him

Not it will vent into the attic. Must be a kink in the ventelation hose, or it came loose from the bathroom vent, not sucking the fumes and moisture from the bathroom.
