Your search for the best attic fan 2021 begins as summer starts approaching. Who doesn’t remember how hot it can get during the summers, even with a good air conditioner at work. The thing about ACs is that, while they help keep a part of your home cool and comfortable, the other parts of your home might still be heated up due to poor ventilation.

Especially when it comes to your attic, although it may not be in use most of the time, it can still be one of the major reasons behind your home, or different parts of it, being hot despite the AC running for hours! The upper floors of houses tend to heat up faster than the lower portions, making it quite challenging to stay indoors, especially for those living on the upper portion of the house.

An air conditioner is not the only solution to this; a proper ventilation system is an absolute necessity in this regard. And hence, your search for the best attic fan 2021 begins!

Choosing the right attic exhaust fan for your home

Choosing an attic exhaust fan is not something you would want to go about casually. There are several factors that you need to consider before you can go through with your purchase. Plus, with the wide variety of attic fans available in the market and the unique features they offer, it can be quite a challenge to pick a winner.

However, here’s a small list of some of the key factors that you need to consider before you decide to purchase an attic exhaust fan for your home.

Attic Fan CostCost stands amongst the most critical aspects of an attic exhaust fan. If you aim to get your hands on a reliable house fan, you need to be willing and able to spend on it. That’s one of the greatest realities of life. The better something is, the more it costs.

However, another reality of life is the scarcity of resources and the choices we’re all forced to make in response to the said scarcity. What you need is a reliable and efficient attic exhaust fan that meets your home’s ventilation needs without putting any strain on your pocket.

Centrifugal Propeller Attic Wall Fan

Model of the house fan

As mentioned before, there are numerous models of house fans, each with its very own set of features that separate it from competitors. That being said while browsing through the various models searching for the one that’s right for you, keep an eye out for these three features:

  • Fan’s Location:

Each house fan model is specifically designed for a certain location in the home, for instance, a duct, roof, or wall. Therefore, be very mindful of the location an attic exhaust fan is designed for. Although not every house fan will be ideal for every location in the house, most of the basic structure of an exhaust fan is pretty much the same. 

Hence, having a basic understanding of how ventilation works and its structure will go a long way in helping you choose the right attic exhaust fan for your preferred location.

  • Centrifugal vs. Propeller

When it comes to choosing between centrifugal and propeller fans, centrifugal fans are usually the best option. That’s mainly due to a number of factors. Centrifugal fans are not only quieter than propeller fans, but they’re also quite efficient when used at high static pressure. On the contrary, propeller fans can hand a huge volume of air at pretty lower static pressure.

Moreover, while the motors installed inside the airstream of the propeller fans make it hard for the said fans to treat air temperature as high as 40° C or more. Contrarily, centrifugal fans come with motors installed on the outside of the airstream. This position of the motors makes centrifugal fans ideal for cleaning highly contaminated air comprising a high temperature.

  • Belt Vs. Direct Drive

Belt drive fans are ideal for air volumes and static pressures, while direct drive fans are more suited to lower static pressures and air volumes. Most of the high-temperature fans exceeding 50° C in temperature usually fall under the belt-driven fans category. Direct drive fans, however, are quite low maintenance and hence, a budget-friendly option.


The sound level of an attic exhaust fan

Another one of the key points to consider is the level of sound generated by an attic exhaust fan as it runs. In the fans industry, the level of sound pressure is often measured in terms of sounds. Familiarizing yourself with the sound levels and how they are measured can easily determine the level of sound or noise a certain attic exhaust fan may generate.

This will allow you to make the right choice for your home. An ideal house fan is the one that makes lesser sounds. Choosing a house fan that makes no noise or does so on an insignificant level is the ideal approach. Otherwise, an attic exhaust fan that makes noise continuously as it runs can be quite frustrating for one to bear. It could also create a chaotic environment at home.

Attic Solar Fan


Types of Attic Exhaust Fans

Choosing the best attic fan 2021 is not as easy a task as it may seem. There are hundreds, if not thousands, of ventilation attic fans from numerous companies just waiting to be discovered and explored by you. Some of the common types of attic exhaust fans have been listed below:

Attic Solar Fan

As the name suggests, an attic solar fan runs on solar energy, which makes it quite a cost-efficient ventilation option for your home. Not only do you not have to depend on your local power supply, but it also puts your worries regarding super-high electricity bills to rest. Your attic solar fan works entirely on solar energy and; thus, it can help you make huge savings on your energy bills.

A whole house attic fan

A whole house attic fan is designed to manage the ventilation requirements of your entire house. Hence, if you want your entire home to be cool during hot summer days, choosing a quiet cool whole house fan would be the right approach to adopt.

A house fan will make your home cool and comfortable and provide it with a soothing atmosphere during hot summer nights, while everyone else without a good whole house fan installed in their homes would be tossing and turning throughout the entire night.

Electric Attic Exhaust Fan

Electric attic fans, contrary to attic solar fans, run on electricity and are one of the most common types of fans available in the market. They may not be as cost-efficient as an attic solar fan, but they are more than makeup for efficient ventilation.

With an electric attic exhaust fan installed in your home, you don’t have to worry about your home being too hot during the summer. However, an electric attic fan cost can put a significant strain on your budget. Hence, be mindful of your financial constraints when choosing the right electric house fan for your home.

Non-Mechanical Attic fans

A non-mechanical attic exhaust fan is one of the oldest ventilation systems in history. People started using them as early as the 1800s. These attic exhaust fans are also known as the gable vents. Like any other kind of attic exhaust fan, non-mechanical attic exhaust fans come with their own unique sets of pros and cons. It’s up to you to decide whether a non-mechanical whole house attic fan is the right choice for you or not.
