Attic Fans: Benefits, Types & Installation

#Home Tips #Uncategorized

Attic fans, also known as attic ventilators, are installed in the attic space of a house to improve ventilation and prevent the buildup of heat and moisture. They draw in cooler air from outside and expel hot, moist air from the inside of the attic. This helps regulate the temperature and humidity levels in the house. In this blog, we explore the benefits of fans in your attic, the types available, and steps needed for installation.

Benefits of Attic Fans

  1. Improved Energy Efficiency: These fans help to reduce the load on your air conditioning system by lowering the temperature in the attic space. This results in lower energy bills and extend the life of your HVAC system.
  2. Increased Comfort: By removing hot, humid air from the attic, fans improve the overall comfort level in your home. This is especially beneficial during the hot summer months. In fact, attics can reach temperatures of up to 150 degrees Fahrenheit.
  3. Prevention of Moisture Buildup: Fans help prevent the buildup of moisture in your attic, which can lead to mold and mildew growth. They also help you avoid costly water damage and improve indoor air quality.
  4. Extended Roof Life: By reducing the temperature in the attic, fans help prevent shingles from deteriorating due to excessive heat.


There are two main types: roof-mounted and gable-mounted.

  1. Roof-Mounted: These fans are installed on the roof of your house. They are designed to remove hot air from the attic space. You can choose an electric or solar attic fan.
  2. Gable-Mounted: These fans are installed on the gable of your house. They are designed to draw in cooler air from the outside and expel hot air from the attic. They are also available in electric or solar models.

Both types of fans are available in different sizes and air flow capacities. So, it’s important to choose the right size and model for your home based on the size of your attic and ventilation needs.


We recommend hiring a licensed electrician or handyman for your installation, given there is wiring involved. TheQwikFix has a network of electricians available to support on all of your electric needs with the click of a button on our website.

To install a fan, they will first choose the right location for optimal ventilation. They will then cut a hole that is the same size as the fan and secure it with screws and sealant. From there, they will install the proper wiring and perform tests to be sure everything is working properly and safely.

Fans are a great way to improve ventilation, regulate temperature and humidity levels, and prevent moisture buildup in your attic and home. With the right size and type of fan, and proper installation, you’ll enjoy the benefits of improved energy efficiency, increased comfort, and extended roof life.
