Attic Fans Features to Consider

Installation & Location

Installing an attic fan should not take you a long time. If you’re skilled, you shouldn’t even have to ask for help. However, different brands offer different installation techniques. Make sure to research the installation procedure before you settle on one attic fan.

You should also consider where the ventilator should be installed. Some are easily attached to a window or wall opening, while others can be placed on the roof and don’t require access to the attic.

Power

You’ve probably heard that attic fans can save you money. It is true; an attic fan will “eat” significantly less energy than your AC unit. Thus, you can use your ventilator as a way to save on energy costs. 

The average attic fan will use under 300 watts. That is less than a whole house fan that can draw up to 700 watts, and a central unit that can reach 5,000 watts. Always check the consumption of the attic fan in advance.

Weather Protection

Since a part of your attic fan will always be exposed to the outside world, you need to think of weather protection. Can your attic fan withstand the elements? Some can! Most solar attic fans, for example, can withstand snow, hail, and even hurricanes and tornadoes. 

Heavy-duty aluminum, that is used in the production of many attic fans, is not damaged by moisture, heat, and impact. Make sure your attic fan is made from durable materials.

Control – Thermostat & Manual

You will find that most attic fans come with a thermostat. The thermostat is what controls the fan and makes it work. The thermostat detects rising temperatures. Once the temperature reaches a certain pre-set point, it will activate the fan. 

In winter, the responsibility falls on the humidistat. When the humidity exceeds a certain level, the fan turns on. Some brands allow you to control the fan and check the attic temperature using their smartphone app.

Size

Much like all fans, attic fans come in all shapes and sizes. In order to determine which size fits your needs, you need to specify what you’re looking for. Do you need an attic fan to cool your whole house, or are you looking for a fan for a small crawl space? 

A smaller fan will not be able to control the heat in your whole house; you will need to get a larger fan for that.

Durability & Warranty

Most attic fans are made from durable, corrosion-resistant materials that promise to serve you for a long time. Generally speaking, the average warranty on an attic fan will reach 10 or 15 years. In approximately 10 to 15 years the motor will start to give in and the fan will need replacement.

Always check the warranty offered with the fan you’re buying. A good warranty will make maintenance so much easier and extend the life of your fan.

Benefits of an Attic Fan

Save money – Reduce expensive AC bills at home.

Air conditioning is necessary in summer, especially if you live in a warmer state. Unfortunately, it can get quite costly. One of the reasons your house is getting so hot could be because your attic is not properly ventilated. 

An attic fan will lower the overall temperature of your house, so you won’t need to spend so much on AC.

Healthy Living – Prevent mold and allergens

An attic fan will prevent excessive moisture in your attic. Moisture can lead to mold and mildew, problems that are often expensive and difficult to fix. 

Mold can cause allergic reactions and health problems in people with respiratory issues. The worst part is, it can go unnoticed for months, as people don’t often inspect the attic.

Save energy – Thermostat control

In the summer months, a large chunk of your energy bill goes towards cooling your house down. With an attic fan, you can save money and energy. 

An attic fan can cool down the whole house in just a couple of minutes. Reduce the temperature and stop relying on your thermostat to do the job!

Common Questions Relating to Attic Fans

What is an attic fan?

Some states get really hot in summer and staying home can be a struggle. Heat rises, so those living on the upper floors can have it so much worse. That’s why some people install attic fans to cool down the attic of their house and keep the temperature in check.

The way an attic fan works is that it exhausts hot air, but it also needs vents to draw in fresh air. You can usually control it using a thermostat. When it comes to mounting an attic fan you have the choice of installing it in the gable end or the roof. It is most often used in the summer months.

How does an attic fan work?

Attic fans cool the house by creating a breeze through the open doors and windows. If you get an attic fan that is sized for your house, it should only take the fan around 3 minutes to blow out all the hot air in your house. The hot air is replaced with cool air from outside.

Attic fans are a great alternative to air conditioning units and whole house fans. They are significantly cheaper. People often get sick from AC blowing cool air directly; attic fans don’t do that. It only takes an attic fan a few minutes to cool down your home.

What temperature should I set my attic fan thermostat to?

Most attic fans rely on a thermostat to give the signal to turn on. The thermostat will work automatically, but you still need to set the temperature at which the fan should turn on.

It is recommended to keep your attic fan temperature between 100 and 110 degrees Fahrenheit. This should work for an average attic fan user. If you live in a state that gets especially hot, hike the temperature higher to keep the fan running for longer.

The Verdict

Attic fans are very useful in keeping your house cool and moisture-free. If you want to give your air conditioner a break and minimize your energy costs, an attic fan will help you do just that.
