Considerations for Best Attic Fans in 2021
There are things you have to take cognizant of before buying an attic fan. This buying guide will properly guide you to make the right choice. Below is what you must look out for before clicking “Buy Now”.
Before we start, it makes sense to explain what an attic is.
What is an attic fan?
An attic fan is a fan that provides ventilation and regulates the heat level in the attic of a building. An attic fan is also called an attic ventilator. An attic fan can turn on and off automatically. It is usually controlled by a thermostat or through a manual switch. An attic fan can either be a gable mount or roof mount. The attic ventilation fan will require extra vents to blow in the fresh air as it exhausts hot air.
Build quality –
This is very important. Completely avoid master flow attic fan that is made of plastic. Metal is the best material for an attic fan. Metal lasts longer than plastic. But if the plastic material is of a higher standard, you can go for it. The best way to do that is to go to a local store to feel the quality of the plastic materials.
Don’t compromise safety for anything. Safety is important when installing the attic fan. It’s different from baseboard heaters. Don’t be carried away by the stylish design of the fan. Always go for an attic fan that comes with a cover. It helps to prevent insects, lizard or birds from getting trapped inside the fan. Also, try to wear protective gloves and hats when installing an attic fan. Things can wrong in the attic but the injuries can be mitigated by wearing safety gear. Whatever you want to do in the attic, the first precaution is to shut off the circuit breaker. Forgetting to do this, can lead to calamitous consequences. Don’t install an attic fan in an environment where there is a gas heater. This is very dangerous. Avoid plugging different appliances to one extension cord. It makes sense to have a separate extension cord for your attic fan installation.
Ease of installation –
One way to cut costs when buying an attic fan is to look for a fan that is easy to attic fan installation. Calling in a professional will cost you nothing less than 50 dollars. Installing the fan all by yourself will reduce the overall cost of the fan. A solar-powered attic fan is a lot easier to install. It requires no wiring and can be mounted with ease on DIY
This is an important aspect when choosing a quiet cool attic fan or whatever. You need to choose a fan that will bring you comfort. Look for a fan that can suit your style and fit your roof perfectly. Take a photograph of your roof and go to a local store in your area to know the right fan suited for your home. The point is that you need to make inquiries and ask questions before you buy an attic fan. Also, look out for a fan with a thermostat. It is a big advantage to have an attic fan with a built-in thermostat and humidistat.
This is another important decider when purchasing an attic fan. Generally, most attic fans are very affordable. The cost may rise when you include the cost of installation, accessories, installation products and materials to the cost of the attic fan. All of this shoots up the cost of fans in the end. So, look for an attic fan that has the complete installation hardware. This doesn’t mean you won’t buy some extra accessories or materials but it will be minimal. Having your installation tools makes everything less expensive.
Air volume –
The air volume of an attic fan is as good as the fan itself. The amount of air the fan can pull in will determine how fast it can reduce the humidity in the attic. The air volume is measured in CFM. The higher the CFM, the better the air circulation. You have to check the CFM of any fan to have an idea of how fast it can cool the attic and the home. For a solar powered attic exhaust fan, always look out for the CFM when it is on a low setting because, for some solar-powered attic fan, the setting automatically returns to low when the weather of cloudy.
Mounting place –
It is important to find the right place to mount the fan. Where you mount the fan will determine how well it will be able to reduce heat. Ensure that where the fan is finally mounted is a place that has a lot of heat.
Fan blades –
The attic fan blade is an important part of a fan. You have to check the construction of the blade and its size too. Check out the rotation rate. The rotation rate determines how faster the fan can cool the attic.
Power consumption –
Checking out the power consumption of the fan is another important aspect to look out for before buying an attic fan. The lower the watt, the more you conserve energy and save money.
Noise level –
It is hard to find an entirely quiet attic fan. But if the noise level is bearable and the fan works effectively, you might need to ignore the noise as far as it doesn’t make anyone feel uncomfortable.
