What is an attic fan and how does it work?

An attic fan is a mechanical ventilation device installed in the attic of a house to provide ventilation and reduce heat buildup during the summer months. It works by drawing hot air out of the attic space and allowing cooler air to enter through soffit vents or other openings.

The fan is usually controlled by a thermostat that turns it on when the attic temperature reaches a certain level, typically around 100°F to 110°F. When the fan is on, it creates a negative pressure in the attic, drawing hot air out and allowing cooler air to enter. This process helps to reduce the temperature in the attic and can also help to reduce the load on air conditioning systems.

Why is it necessary to cover the attic fan in winter?

It is necessary to cover the attic fan in winter because it can allow cold air to enter the attic space if left uncovered. During the winter months, the fan is not in use, and the opening can act as a pathway for cold air to enter the attic, reducing the energy efficiency of the home. Cold air can also cause moisture to form in the attic, leading to condensation and potential damage to the roof and insulation.

Covering the attic fan helps to prevent heat from escaping through the opening, reducing the load on heating systems and keeping the home warmer. Additionally, covering the fan helps to prevent cold air from entering the attic, reducing the risk of condensation and moisture damage.

How do I cover my attic fan?
