The duct work probably runs through an area that is hot and humid, i.e. attic space, and it isn't insulated.
is your fan running in the correct direction? are any of your ducts blocked?
The purpose of the plumbing vent on the side of the house is to allow air to enter the plumbing system, preventing air pressure buildup and ensuring proper drainage and flow of water through the pipes.
When warm, moist air from the clothes dryer exhaust vent meets the colder air outside, it can cause condensation to occur. This condensation forms water vapor, which can appear as clouds or steam coming out of the vent.
Heat would flow from the air coming out of the floor vent to the cooler air in the room. The warmer air is at a higher temperature and naturally moves towards the cooler air to create thermal equilibrium in the room.
The air conditioner is low on refrigerant.
The A/C extracts water from the air.
There may be too much air coming out of the vent due to a blockage in the air ducts, a malfunctioning blower motor, or an issue with the thermostat settings. It is important to check these components to determine the cause of the excessive airflow.
the air coming from the vent is warm
It's somewhat cold. It's just very little cold air coming out. Can't hear the vent blow the air as well.
The dryer vent should be located outside the house to safely expel hot air and moisture.
A rotten egg odor may indicate a dead rodent or animal in or near the ventilation system, whether in a house or car.
