Ventilation Fan Importance

Ventilation Fan Importance
Ventilation Ventilation fans, also known as exhaust fans, help circulate air inside the house, which generally keeps the house warmer in the winter and cooler in the summer. Fans that move air in an enclosed space, such as a small attic, can also help prevent mold and mildew from growing by dissipating moisture. There are several different types of ventilation fans. Some common types include in-line, wall-mount, ceiling-mount, outdoor-mount and combination fans. In addition to these types, fans can be designed for whole house ventilation or serve a specific purpose in a room, such as a stove exhaust fan.
Outdoor-mounted ventilation fans are typically mounted on the roof or outside of the house to draw air from a part of the house.

Why Are Ventilation Fans Important?
In-line ventilation fans are often best for homes where a fan cannot be easily mounted to the ceiling. These fans are placed inside the main duct of the house and are used to suck air through the heating and cooling vents. The air is pushed out of the house by passing through the ducts. Wall-mount and ceiling-mount fans mount directly to the wall or ceiling of a room. These suck air from the room and push it into the ductwork in the same general fashion as inline fans.
Ventilation fans can help prevent mold and mildew from growing in a confined space.

Outdoor-mounted ventilation fans, sometimes called outdoor remote fans, are installed outside the home. They are usually mounted on the roof or outside of the house to draw air from a part of the house. These types of outdoor fans are often used to ventilate attics and crawl spaces to prevent harmful moisture from being trapped inside.

Combined ventilation fans are ceiling or wall models that are installed inside the house. Combination varieties typically offer both light and ventilation. These are often found in bathrooms where the fan can be easily turned on with a wall switch or pull cord along with the light. Some three-way models also have a small heater in the same fixture.
