The problem might be the condensation in the cold duct. In most of the dripping water from the bathroom fan cases, this is the main culprit that you have to consider first. You may notice water dripping during or shortly after taking a shower. There is a good chance that there is condensation inside the duct.

The warm and moist air from your bathroom goes up and meets the cold air from the attic or outside your home. This meetup leads to condensation and will drip water back to your bathroom. This can also happen during the warmer months. The hot and humid summer air will condense when it hits the pipe made cold by the air conditioning system.

Many people notice the issue when the bathroom exhaust fan starts dripping on their head as they step out after a shower. The usual cause is condensation inside the duct. In winter, when the warm moist air from the bathroom hits cool air in the attic or outdoors, it condenses, sending drips back down the ductwork. In summer, humid outside air condensed on a pipe cooled with air conditioning will drip when humid bathroom air adds to the moisture level.

Here is another video of the dripping water sound coming from the bathroom vent: This could be any number of things but based on the A/C inspection report that came back indicating a lot of water intrusion and mold issues, and issues suspected with the ducts, I believe this might be related to another issue with the defective Lennar A/C systems.

The bathroom fan starts dripping when warm moist air condensates in an uninsulated or poorly insulated ventilation duct. As the condensation forms on the wall of the ventilation duct, it begins to drip back down into the bathroom. A leaking bathroom fan can stain ceilings and even cause moisture damage.

Bathroom exhaust fans are installed to remove the high levels of moisture from the bathroom to the exterior of the home. Water can be deleterious to the homes condition, so it is no wonder we install exhaust fans in the bathroom. The problem: The bathroom exhaust fan is terminating in the attic. The fan pulls warm moist air from the bathroom, and distributes the air to the attic. On a cold day, the moisture in the air will condense on anything below the dew point.

Similarly one may ask, why is my bathroom vent leaking when it rains? If the bathroom fan is dripping water when it rains, it means that the flashing or some part of the vent cover is allowing in water. It may also be the flap that is loose or missing and is allowing in water. In short, you will have to get someone onto the roof to fix it.

Why Is My AC Vent Leaking Water? Let’s start with the basics: An air conditioner works by absorbing the warm air and moisture from your home and changing it to cool air. When the air is pulled in, condensation drips from the AC coils to what’s called a drip pan. From there, the water is flushed out of your home through a drain pipe/line.
