Remove Vent Clog & Improve Airflow One reason you may be getting condensation in your fan is that the bathroom vent hose is clogged. Many homeowners don't realize that birds love nesting in bathroom and dryer vent hoses. As a home inspector (and an air duct cleaning company owner), I have probably seen over a hundred birds nests in air vents.
Change The Position Of The Fan We often do this mistake by installing the fan right over the shower or the tub. If you do so, it will get the air at its warmest point. This will ultimately lead to the condensation of the air quickly in the ventilation pipe.
Sometimes, particularly when a bathroom exhaust vent extends through an unheated section of your home, the possibility of condensation buildup can occur. When this is the case, warm, moist air from the bathroom can condense on the inside of the cold duct and can run back down into the bathroom.
Mold on the bathroom ceiling is caused by high levels of humidity from baths and showers. Poor ventilation does not allow the moisture to escape from the bathroom. Therefore, this causes condensation and water droplets settle on the bathroom ceiling day after day and makes it damp and moist.
The hot and humid summer air will condense when it hits the pipe made cold by the air conditioning system. The bathroom air will add more moisture and this will lead to condensation. Condensation can also happen in the vapor barrier that you had installed in your roof. If it’s poorly insulated, the water may end up pooling.
Also asked, how do I stop condensation in my bathroom fan? How To Prevent Ceiling Stains Around Your Bathroom Exhaust Fan. Use an insulated duct inside the attic. This is a no-brainer.

Bathroom exhaust has a very high dew point. As soon as it hits a surface colder than dew point, condensation happens. With insulation, condensation will occur much higher up, but it will happen. Then it runs back down the duct to drip out of the fan into the room.
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.
The cause of condensation Moist indoor air condenses inside a cold, uninsulated duct and water runs down into the fan. Water stains on the ceiling around your bath fan may indicate a leak coming from the vent cap on your roof, but condensation is the more likely culprit.
When a fan is ducted out the side of the house (or through a soffit), cold air from outside can migrate back through the ducting and chill the fan can. Then internal humidity aerosolized by warm inside air can condense on the inside of the chilled fan can. This built-up condensation then drips back through the grill and onto the floor.
