How Does an Attic Fan Work?

post img

When the scorching summer heat is upon us, finding ways to keep our homes cool becomes a top priority. As an energy-efficient and cost-effective solution, attic fans have gained popularity in recent years. These nifty devices help regulate indoor temperatures, making our living spaces more comfortable during hot days. But have you ever wondered how an attic fan works? Today, we’ll delve into the mechanics behind these cooling wonders and explore why My Buddy the Plumber is your go-to expert for all things related to attic fan installation and maintenance.

Understanding the Basics: What is an Attic Fan?

Before we explore the inner workings of an attic fan, let’s briefly discuss what it is. An attic fan is a ventilation system installed in the attic of a house. Its primary purpose is to expel hot air from the attic, preventing it from seeping into the living spaces below. By doing so, it helps reduce indoor temperatures, lighten the load on air conditioning systems, and potentially cut energy bills.

Types of Attic Fans:

There are mainly two types of attic fans:

Roof-Mounted Attic Fans: As the name suggests, these fans are installed on the roof of the house. They are often connected to a thermostat or a humidistat that activates the fan when the attic temperature rises above a set threshold or when humidity levels are too high.

Gable-Mounted Attic Fans: These fans are installed in the gable, which is the triangular portion of the wall between the two sloping sides of the roof. They work similarly to roof-mounted fans, but their installation location may vary depending on the house’s design.

The Mechanics Behind Attic Fans:

An attic fan operates on a simple principle: hot air rises. During sunny days, the temperature inside the attic can soar, reaching well above the outdoor temperature. Without proper ventilation, this trapped heat can transfer down into the living spaces, making the interior uncomfortably warm.

Here’s how the attic fan comes to the rescue:

Exhaust Ventilation: The attic fan works as an exhaust system. It is positioned in such a way that it draws air from the attic and expels it outside. As the hot air is removed, it creates a negative pressure environment inside the attic, which causes cooler outdoor air to be drawn in through the soffit vents or other openings.

Thermostat/Humidistat Control: Most modern attic fans are equipped with a thermostat or a humidistat control. The thermostat allows the fan to turn on automatically when the attic temperature exceeds a predetermined level. Similarly, the humidistat control activates the fan when humidity levels rise to a certain point. These controls ensure that the fan operates efficiently and only when necessary.

Energy Efficiency: Attic fans are designed to be energy-efficient. By actively removing hot air from the attic, they reduce the workload on air conditioners, resulting in potential energy savings and a more sustainable approach to cooling our homes.
