How To Choose Your Perfect Attic Fan - Buying Guide

  • Safety

Always practice safety when you install the unit. Preferably, you want to buy the attic fans that has a cover. Not only is it stylish and incognito, but it will protect birds and insects from falling inside. Sometimes mounting the fans could be an extremely dangerous activity, depending on the interior design of your attic. This will create an inconvenience if you need to reach up and not paying attention to your surroundings.

Keep in mind that you are in an attic, so things can go wrong at any time. Always practice a safe installation when working on any piece of machinery by wearing hard hats and gloves. Moreover, bring ladders and the right type of tools with you. If you need the whole house fan, it is good to repair or install it on a work desk. Then, take it upstairs to the attic and complete the process.

Whatever you do, make sure the circuit breaker switch for the attic is turned off. Not unplugged, but turned off completely. Triple check it to make sure. Another piece of advice is to never install the attic fans in a house that has a gas heater or gas furnace. When the attic fans are turned on and those appliances are going, the dangerous gas buildup could create a potentially deadly situation.

Just to give you a note, if you use proper ventilation, it will prevent to from buildup the excess moisture. Even, it will also keep your attic space mold-free.

Moreover, if you do not have installation tools, you might need to buy them. However, the money you pay upfront is worth the amount you will save later.

Why & when to use an attic fan?

  • Why?

An attic is an expensive way to lower the temperature in the home. The hot air from the outside flows out of the attic while the cool air flows inside the windows. This creates a comfortable environment for everyone in the house to enjoy. More water vapor is created when the dishwasher is going, house guests are cooking, or when someone is bathing. These droplets can travel into light fixtures, exhaust fans, and rafters which will eventually damage different parts of the home. Or, they can become frosty over time during the winter. Mold and fungus can also grow as well. Studies show that long-term exposure to mold can have harmful effects. An attic fan prevents this from happening by regulating the temperature. It pushes out the hot, stuffy air and pulls in the fresh air. Solar fans are wireless, so they are convenient to operate. Also, they have no carbon footprints which limits the amount of fossil fuels floating into the air from power plants.

  • When?

Most articles suggest that you should use an attic fan during the late evenings and early mornings. Moreover, attic fans should be used heavily in the summer. You can click here to learn more about why and when to use an attic fan.

Are attic fans worth it?

Attic fans are definitely worth the money that you spend. In the long run, they keep the house cool, so all guests and residents stay relaxed and comfortable. The air stays fresh, which helps people stay healthy and happy. More importantly, attic fans are energy-efficient. Therefore, you will save money. Central air and box fans will eat up the electricity bill when they are constantly running. However, the attic fan uses the least amount of energy while delivering maximum results. Most attic fans run about 10 to 15% the amount of electricity compared to regular air conditioners. Moreover, they reduce allergen and the risk of asthma. Attic fans are an overall great investment, especially in the summertime. Visit this page to read more.

FAQ:

  1. What is the purpose of an attic fan?

An attic fan regulates the temperature of a building. The exhaust pushes hot air out into the atmosphere while the cool air comes in through the windows. You can change the temperature based on the thermostat programming. You can also mount an attic fan on a gable or roof. It is your choice.

  1. What size attic fan do I need?

It really depends on the size of your house. Of course, a large house needs a large fan. In this case, you might want to consider getting a 24-inch fan. That should be big enough. Two units might be needed for multi-family houses. Smaller houses would be just fine with a smaller 14-inch fan. One important aspect while shopping for an attic fan is looking for the CFM (cubic feet per minute). One equation you could use to ensure you are buying the correct fan is dividing the cubic feet of air per minute by 300. The higher the CFM the more space it can reach. Therefore, a larger fan is needed.

  1. What temperature should an attic fan get set at?

Most professionals recommended that the thermostat settings should get programmed between 100°F to 100°F. Others suggest keeping the temperature between 95°F to 100°F. Although this temperature may seem high, the fan will regulate the indoor climate properly. Automatic fans will start when the attic reaches a certain humidity.

  1. How many attic fans do I need?

You only need one. Just make sure that you purchase a high-quality product with all the necessary specs. Research the fan thoroughly before buying. The only reason to buy more than one fan is if you have more than one attic or a bigger house. Always make sure that the unit can supply enough air to the entire house. The bigger the house, the bigger the unit. Also, you can purchase an extra backup fan just in case the motor fails on your primary one.

  1. How to calculate the CFM for an attic fan?

You can use an Attic Fan Calculator to get this information. Simply type “Attic Fan Calculator” into your preferred search engine. You will find multiple websites catering to this CFM finding process. The website will ask for the type of attic area, attic height, roof construction, and even the color of your attic fan. This information will be used to get the required CFM. You could also measure the length times the width for each floor. Then, multiply the total by the height. After that, add everything together. Viola!

Final Verdict

You have just finished reading the detailed guide about choosing the perfect attic fan for you. There are many attic fans on the market today, but the comparison chart above has given you the ultimate choices. You do not need to worry about suffering inside a hothouse anymore because the attic fans will push out the hot air and bring in the cool air, which will melt the stress and frustration away.
