For many of us, our attics, with their out of the way location, are a convenient option for storage of all sorts of stuff. 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 that cold air. The greater humidity also causes considerable build up of moisture. The high temperature and moisture build-up can result in destruction of stored items, compromise in the integrity of your roof and your home's overall structure even. It is for this reason that attic fans are such critically important implements. Because of the important function they subserve, getting good quality models for a reasonable price is important. We have put together a list of 7 of the best attic fans in 2021 along with the features that make them stand out, for your reading pleasure.
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. And it is this purpose that an Attic Fan subserves. 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.
What Is An Attic Fan?
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 the entire living area as well. 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.
What Advantages Are There To Getting An Attic Fan?
Attic fans help to keep your attic moisture-free and control the temperature. Moisture build-up can cause the growth of mold which can trigger allergies in certain people.
They help to preserve the integrity of your roof and other structures as they can be damaged by moisture. This could end up saving you several thousands in repair costs.
Attics are very often storage spaces, controlling the moisture reduces the chances of your stored goods getting destroyed.
With an attic fan, there's less need to run your air conditioning, this serves to reduce your power consumption.
What Factors Should I Consider Before Buying An Attic Fan?
We already covered how vitally important attic fans are. And as you know, when shopping for anything at all, especially for things that are important to one, making a choice can be a hellish prospect, one very often finds oneself overwhelmed, and unable to make a decision. To help you with this, we have given you a list of 7 of the best attic fans on the market, and we'll not 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 as these would better deal with the conditions 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.
Ease of Use
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/off. This may not be such a bad thing if it works for you, but the thermostat option is, for most, the preferred option.
Ease of Installation
Attic fans are either Gable or Roof-mounted. The gable mounted sort is typically easier to install. Roof-mounted attic fans 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 because 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 run up your electric bill needlessly.
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 unit is properly installed and stable as instability can result in vibration and noise production.
Several energy-saving models are available in the market today. 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.
How Much Does An Attic Fan Cost?
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. Attic fans can cost as little as $60 or as much as $550 dollars.
