Install an Attic Ventilator Fan

05/03/2023

Why do they matter?

Attic ventilator fans are an important component of a home’s cooling system during extreme heat situations, providing several benefits, such as reducing heat buildup, preventing moisture damage, extending roof life, and lowering energy costs.

What do I need to know?

Attic ventilator fans are installed in the attic of your home to help regulate the temperature and humidity levels in the space. The fan works by drawing hot and humid air out of the attic and replacing it with cooler, drier air from outside.

Attic ventilator fans come in different shapes and sizes, typically consisting of a motorized fan blade housed within a frame or housing. The fan is usually mounted on the roof or in a gable vent and is connected to a thermostat that automatically turns it on and off based on the temperature in the attic.

Some types of attic ventilator fans are powered by electricity, while others are powered by solar panels. They can be useful in reducing cooling costs by preventing the buildup of hot air in the attic, which can transfer heat into the living spaces below.

Extreme heat can cause damage to roofing materials, such as shingles, by causing them to expand and contract, leading to cracking and other damage. Attic ventilator fans help to reduce heat buildup, which can prolong the life of roofing materials and prevent premature deterioration.

Lowering Energy Costs: When attic temperatures rise, it can cause the air conditioning system to work harder to keep the living space cool, leading to higher energy costs. Attic ventilator fans help to reduce the temperature in the attic, which can reduce the load on the air conditioning system and lower energy costs.
