Buyer's Guide

Our comprehensive buyer's guide will take you through all there is to know about attic fans and how exactly to buy one.

Benefits of Attic Fans: Does My Attic Really Need One?

We see that you're wondering whether your attic really needs a fan or not. Well, let us take you through two benefits of an attic fan that make them a must-have for your home.

Cools your home

This one's odd, isn't it? How can a fan that is blasting air all the way up in the attic lower temperatures in your house's living areas? Well, since it is the hottest room of the house, your attic can increase the overall temperatures of your house's living areas, especially those whose ceiling meets the floors of your attic.

By simply ventilating the room with an attic fan during the hottest parts of the day, you can lower the overall temperatures of your home. This will also help you slash cooling costs since your air conditioner will now have a little buddy giving it a much-needed helping hand.

Extends your roof's life

Do you know that over time, humidity can seriously damage your roof? Well, moisture tends to rise with the heat. So, if you live in a humid region, chances are a large amount of moisture ends up in your attic. This can cause mold and mildew to grow there and no one wants that. The easy solution to protect your roof from this nuisance is to ventilate your attic with a fan.

What Are the Different Types of Attic Fans?

Generally speaking, you can buy three types of attic fans based on the resource that powers it up.

- Electric
- Solar
- Wind-Powered

Now, let's look at the factors that differentiate each type from one another.

Electric

Electric attic fans utilize our good friend, electricity, to power themselves up. These bad boys usually also boast thermostats in their designs. What this does is the fan gets automatically toggled on or off depending upon the room's temperature. Furthermore, electrical attic fans are also great at funneling large amounts of air in a very short period. Efficiency through and through.

Solar

Solar attic fans are some of the cheapest and most popular attic fans available. By utilizing radiation from the sun, these devices slash your power bills and also contribute to the green movement- that's a resounding 'yes' all around.

On the flip side, these fans can't really work their magic when sunlight is low. Nevertheless, the best solar fans, like the ones on our list, have sufficient batteries to last you through many days of darkness.

Wind-powered

If you're all for the green revolution but don't really fancy a solar-powered attic fan, a wind-powered one may just be for you. However, it is important to note that this type of attic fan will only work in windy regions since that is what generates its power. When these fans work, they operate with excellence and can be a great way to reduce your power bills.

What Should I Look for in an Attic Fan?

We recommend considering two factors when you're in the market for a new attic fan.

CFM

CFM, or cubic feet per minute, is a rather fancy term, isn't it? Well, it basically signifies the area that the attic fan will ventilate. This number is usually found on the product page or package.

So, what CFM does your attic need? Well, this can be found by measuring the room's cubic footage. You basically multiply the floor's square footage by the room's height. A larger attic will require a fan with a higher CFM rating and vice versa.

Thermostat

Unless you're living in a horror movie, chances are that your visits to the attic would be rare. So, the fan must be able to toggle itself on or off without you having to pay it a visit. It is for this very reason that the highest-quality attic fans boast pre-programmable thermostats. They may be adjusted to control the fan according to the room's temperature.

How Much Do Attic Fans Cost?

Attic fans can cost you anywhere from $50 to upwards of $500 depending on their size and features. As the price tag goes up, you can start expecting a fan that has a superior build quality, has high CFM ratings, and boasts advanced features like a thermostat and a humidistat.

We must mention that like with most devices, a high price tag doesn't really guarantee a superior attic fan. It is no use spending on a fan with high CFM if your attic is small. What is important is that you seek a high price to performance ratio and spend according to your needs.

Some Attic Fan Buyers Ask

We all know that an article without an FAQ section is a boring one. So, here are answers to some frequently asked questions regarding attic fans.

Q: Do attic fans really help?
A: Attics are prone to reach extremely high temperatures due to their exposure to direct sunlight. With an attic fan ventilating the room, you can expect the attic's temperature to go down. This will in turn cool your living areas and also help you save on cooling expenses. Furthermore, attic fans also extend your roof's life by preventing the buildup of moisture.

Q: What should I look for in an attic fan?
A: The best attic fans are not only great at ventilation but are also easy to assemble and operate quietly. We recommend looking for ones with a built-in thermostat and a CFM rating that is adequate for your attic's size.

Q: What's the difference between an attic fan and a whole house fan?
A: A whole house fan is all about drawing out the air from your entire house and throwing it in the attic. What the attic fan does is that it takes the air inside the attic and ventilates it outside.
