For many of us, our attics are a convenient option for storage of all sorts of stuff. Their out-of-the-way location makes for a perfect place to keep extra items. Without proper temperature control, especially in hot summer months, the temperature in your attic can rise to as much as 150°. This temperature rise is more pronounced in the attic because of the tendency of hot air to rise due to its weighing less than cold air. The greater humidity also causes a considerable build-up of moisture. This is where attic fans come in. The high temperature and moisture build-up can result in the destruction of stored items, compromise the integrity of your roof and your home’s overall structure even. It is for this reason that an attic fan is such a critical aspect of home improvement.
Because of the important function they serve, getting a good quality attic fan for a reasonable price is important. We have put together a list of the top attic fans in 2023, along with the features that make them stand out, for your reading pleasure. Bring cool and fresh air into your space with one of these picks.

Temperature control in your attic – especially in the warmer, more humid summer months and for people that live in warmer climates – is of great importance. An attic fan serves this purpose. For those unfamiliar with the term, an attic fan isn’t just a fan you plug into a power source and place in your attic. It is a specialized implement made specifically to control temperature and humidity in your attic. It can also improve overall attic ventilation and make your living space more comfortable.
An attic fan, also called a powered attic ventilator or a whole house fan, is a ventilation fan that works to regulate the temperature of a building’s attic by pushing hot, humid air out and replacing it with fresh air from the outdoors. This serves to cool not only the attic, but your entire living space as well. A whole house fan like this can work alongside your air conditioning to lower the temperature of your home.
Attic fans often contain thermostats that turn the fan on and off as the temperature rises and falls. Some of them also come with manual control switches. Attic ventilators are typically powered by electricity or solar power, with some models offering both, wind-powered models are also available. An attic fan can be gable- or roof-mounted.

We already covered how vitally important attic fans are. And as you know, when shopping for anything at all – especially for important ventures of home improvement – making a choice can be overwhelming. To help you with this, we have given you a list of the greatest attic fans on the market. Our list can help guide you through making an informed decision. Here are some of the factors to consider before choosing an attic fan.
Your attic fan is likely going to have to work for extended periods, in hot and moist conditions. With these in mind, it is important that you choose a model that’s built from sturdy, weather-resistant material. These will deal with the conditions more effectively and last longer, saving you money in the long run.
The capacity of how your attic fan determines how much space it can ventilate. This is often given in square feet. You should pay attention to the size of your attic and choose a ventilator that can conveniently subserve that area.
Attic fans very often come equipped with thermostats for automatic temperature control. An adjustable thermostat lets you choose your preferred temperature for the fan to work with giving you greater control over your unit and overall better satisfaction.
Some models do not feature thermostats, however, and require you to manually turn the unit on and off. This may not be such a bad thing if it works for you, but the thermostat option is the preferred option for most.
Attic fans are either gable- or roof-mounted. A gable attic fan is typically easier to install. A roof-mounted attic fan usually require expert installation because of their height.
Also, electrically powered attic fans are usually easier and less expensive to install compared to solar-powered ones.
Airflow capacity, measured in cubic feet per minute (CFM), is another important parameter to consider before purchasing an attic ventilator. It is a measure of the amount of air the unit moves through a particular space. A larger space would require a fan with greater airflow capacity.
Before choosing a ventilator, you should find out what the CFM requirement of your space is. You can do that easily by using an online CFM calculator. Matching the CFM of the fan to your attic’s requirements is important. A fan with too little CFM will not generate enough airflow to cool the room sufficiently, and a fan with too much CFM would not only cost more, but also needlessly run up your electric bill. Paying attention to this important detail will help you make the most of your attic fan. This will in turn improve your attic ventilation and your overall living space, making your whole house fan true to its name.
The newer models are built with an emphasis on stability, reduced vibration, and less noise production. But as with everything else, different manufacturers have varying levels of success with this. You should pay attention to the measures that have been put in place to ensure noiseless operation. You should also ensure that your attic fan is properly installed and stable, as instability can result in vibration and noise production.
Several energy-saving models are available in the market today – solar powered attic fans fall into this category. Getting one of those would mean that you spend less on electricity. You should ensure that the gains you make energy-wise do not translate to reduced functionality, however.
The price of an attic fan depends on a lot of factors, its build material, size, airflow, capacity, manufacturer, and energy source with solar-powered units generally costing more than electrically powered ones. An attic fan can cost as little as $60 or as much as $550.
A: It depends on the model. A lot of models, especially the gable-mounted sort, are very easy to install and do not require professional installation.
A: An attic fan typically has a lifespan of about 15 years, as long as it is properly maintained. You should note that durability is dependent on your particular model.
A: No, it shouldn't. Your attic fan should only run when the temperature rises above a certain point.
