How to use attic fan?

Some people cannot afford or choose not to have central air-conditioning in their homes. If this is your case, then an attic fan is a great alternative to regulate the temperature. First, you need to determine the best intake location. Install the fan in an area where it is the most hottest, which is usually in the attic. You can do it yourself or hire a professional contractor. Some Amazon orders have a professional installation service available.

Read the directions for step by step instructions as you complete the installation. Every little piece matters. Perform each step as you go along through the list because they are hard to memorize. Determine how large your house is by measuring the entire area. Get the length and the width of every room and then multiply those numbers together. Make sure the fan could reach that amount of square feet. Always look for the CFM (cubic feet per minute). After that, just plug in the fan to a power source; it could be a wall current or extension cord. If the unit is a solar fan, then you can simply install it and let the sun do all the work.

Set the thermostat to the desired temperature. Each unit normally has an easy-to-work switch or dial box that requires little maintenance. Opening windows in the lower levels of the house will get the airflow going. Tighten the screws and balance the blades so they stay quiet while turning. Please visit this page to read more.

How does an attic fan work?

An attic fan is a ventilation system that will regulate the heat inside the home and cool down the temperature. Heat typically circulates inside the home and the attic fan pushes it out.

Many attic fans use multiple sources of energy. However, the most popular are electric and solar. The electric energy comes directly from the power socket in the home. The solar energy comes directly from the sun. Both have their pros and cons.

Once you have an attic fan installed it is time to turn on the thermostat to set the temperature. The fan will go to work to achieve the desired climate. When the attic reaches over 120 degrees, that is when the fan will turn on and the cold air is normally pushed out of the vents.

Moreover, the attic fan is energy-efficient since it does not use much electricity. This, in turn, save you lots of money. Always mount the attic fan to the highest point of the house for the best results. Ultimately, an attic fan also reduces indoor allergens and freshens the environment. All of this information and more is described in the link below.

How do solar attic fans work?

A solar attic fan works different from a regular fan. The solar attic fan works with your vents. When the sun is beating down on the roof, an average motorized fan can use a lot of electricity. However, a solar fan is only using the sun for power, which is great for homeowners living in the hot states, such as Florida and Texas. A solar fan uses the free solar energy, which a natural light source, through the high-impact photovoltaic solar panels. That is the best choice for the environment. These fans will run during the day when the sun is out and turn off at night when the sun sets. This means the solar fans will likely last longer than the electric ones. Additionally, solar fans are easy to install when they are fresh out the box.

There is so much more information to learn about solar fans. You can read more here.

How to install an attic fan?

First, determine the square feet of the roof and the vent size. Then, you need to install a shutter. If the gable vent is smaller than the attic fan then you need to get a shutter and remove the old vent.

Look for an area where you want to install the attic fan. Getting a plywood cover might be your best bet for assistance. Cut 2x10 pieces to fit between the ceiling joists. You need to mark them circular diameter of the fan with a pencil. Then, you need to cut around that. From there, you can just put the fan on top of the hole and screw the sides into the shingles. Clear the nails from the shingles. Preferably, the hole should be the same size as the attic fan. Once you snuggle the fan on the roof use the shingles to cover the remaining metal.

If you have a fan without a base then you would need to create one out of wood. For more information about how to do this, click here.

How to install a solar attic fan?

Some solar attic fans are very easy to install. Just read the directions and you will most likely be successful at doing it. Usually, the only things you need is to cut a hole in the place where the solar attic fan will get mounted. Then, screw it into the roof. Some materials that you will need for this job are a reciprocating saw, ladder, drill, wire strip pliers, tape measurer, hammer, a powered screwdriver, and an adjustable wrench. Once you have these things it is time to get to work!

First, you need to lean the ladder up against the house and climb up to the part of the roof facing south. Use the tape measurer to pinpoint 18 to 24 inches from the top of the roof. If you plan to install two attic fans, separate them by at least 15 feet apart. When you are inside the attic, create a circle identical to the diameter of the fan. Drill a screw through the center so you know the starting point on the other side. Create that circle on the other side of the roof as well.

Use the saw to cut around the hole. It could be between 14 inches and 24 inches, depending on the size of the attic fan. Remove the excess shingle material around the circle. Position the fan over the hole and put the intact shingles over the excess panels. You can secure the fan by screwing the ends into the roof.

How to wire an attic fan with a thermostat?

Turn off the power of the circuit breaker for the attic and find the thermostat. Look for the negative and neutral wires which are normally differentiated by white and black cords. If possible, get a voltmeter to measure whether there is an electrical current that comes from the attic fan so you do not get shocked. If so, stop what you are doing and make sure to cut the unit off completely.

You can mount the new thermostat on the rafters on a plywood frame. Get a NM cable and run it from the attic light to the thermostat. Connect the cables. Moreover, you can strip any cable if you find it necessary. Connect the cords directly to the motor. Put the caps on and viola you are done! Put the wires back inside and clamp on the housing.

When this process is completed, restore the power and continue using the fan. Normally, most attic fans come with some type of thermostat directions that you can follow. Or, you can call an expert to wire up the thermostat system if you do not feel comfortable.

How to insulate an attic fan?

It is very important to insulate an attic fan to prevent air leaks. If you have a vent at the bottom of the attic, connected to the main house, then a different insulation material is required. You can move a storage deck, dam, or foam box over the whole house fan. Sealing the rock and pipe holes is also a must. Use caulk, foam, or batt insulation.

Rock wall insulation normally comes with a house. If this is the case, then you are in luck! You could still put some cellulose on top of it for added protection. Make sure the cellulose is leveled out with a rake.

Sometimes you will find a paper or polyethylene attached to the bottom of this type of insulation. It is called a “vapor barrier”. It will catch the moisture from certain insulation material if the attic gets too hot. If the paper barrier is removed, the insulation material will eventually get wet and become useless. You could put it in a perpendicular area of each corner. Feel free to cut the batt insulation if needed. The best part about these insulated materials is that you could still store things in the attic on top of them.

When you want to heat up the house, the vapor barrier should point down. If you want it to get colder, it should point up.

A well-written article based on this will help you to understand more about this.

How to replace an attic fan?

The first step is to think about safety. Turn off the power of the circuit breaker connected to the attic. Then, you can start pulling the shingles off of the roof to get the attic fan loose. Next is to disconnect the thermostat cords which are usually white and black from the fan. Unscrew the caps and remove the screws from the brackets holding the motor in place. Then, wiggle it out.

Usually, the attic fan comes with instructions. You can replace the fan by reversing the steps above and follow the rules of the installation. The process is very simple and easy.

You can read more for some extra information.

How to replace an attic fan motor?

Many customers suggest buying a whole attic fan set that includes the thermostat, housing, blades, wiring, and the motor. It actually costs the same price or sometimes cheaper than the motor itself. In this case, just follow the installation process above. If you decide to only replace the motor, check if the thermostat is still useable. If it isn't, then buy a new one. Wear insulated gloves for protection before beginning the insulation process. Look for a splice box next to the main unit. Unscrew the cap and disconnect the wires. Remove the wood screw from the brackets holding the motor in place. You could use a ⅜ ratchet or hex-head wrench. Bend the brackets and wiggle the fan to get it out. Connect the new motor in the same place. Screw the connectors tightly just as they were before. Attach all the wires to their rightful colors.

This process is easier than it seems. Visit this page to learn more.

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, the attic fans should be used heavily in the summer.

What are the Benefits of Attic Fan & Solar Attic Fan?

An attic fan and solar fan are beneficial because they use a minimum amount of electricity compared to air-conditioning units. Moreover, there is no extra money needed for upkeep. All power comes from the sun feeding the solar-powered units. Additionally, installation is quicker and easier. Both attic and solar fans prevent moisture buildup that could lead to mold and mildew. These harmful organisms deactivate in the cold.

Additionally, attic fans will prevent ice from forming in the attic during the winter months. They also create negative pressure inside the home to keep harmful gases from developing and getting trapped inside. Another important benefit is the roof protection. A high amount of heat can permanently damage different parts of the roof. It can lead to damaged asphalt and cracked shingles. Metal objects around the attic could rust out when extra moisture is present.

Attic fans also adopt the energy from the air conditioning units and central air. This helps keep them from working so hard. It also saves you money the long run from a decrease in electricity bills. Moreover, the lifespan of the HVAC system is extended because these attic fans are cooling the house.

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.

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.

How To Choose The Best Attic Fan – Features to Consider before Buying an Attic Fan

  • Build Quality

The best material for an attic fan is metal. Stay away from plastic because it tends to break quickly. However, if the materials are made with high-quality USA parts and constructed to the highest standards, then you can choose a cheaper material that has a more quality build.

  • Safety

Always practice safety when you install the unit. Preferably, you want to buy an attic fan that has a cover. Not only is it stylish and incognito, but it will protect birds and insects from falling inside. Sometimes mounting a fan 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 anytime. 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 a whole house fan, it is best 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 an attic fan in a house that has a gas heater or gas furnace. When an attic fan is turned on and those appliances are going, dangerous gas buildup could create a potentially deadly situation. When the weather gets cold, make sure to protect the house fan from getting damaged by putting a cover around it. Another piece of advice is to never plug too many power supplies into one extension cord. Try to only connect the attic fan to a new and intact extension cord.

  • Easy to use

It is very important to choose an attic fan that you can install yourself. This way, it saves you money from getting a professional service. Usually, the units that come with instructions are the best ones. The benefits of a solar-powered attic fan are no wiring, easy to insulate, and easy to mount. Luckily, most units are constructed in a way for basic DIYers.

  • Comfort

Choose a fan that you will feel comfortable using. While shopping online on in person, envision a style that would fit your home and roof perfectly. Take a photo of your roof with a mobile device before going shopping. Ask a salesman, friend, or a family member for advice. This attic fan will be the ultimate tool that cools down your home for the best comfort. An attic fan that has a thermostat is a huge plus. Not only can it heat up your home in the winter, but cool it down for the summer. Therefore, your body will stay at a comfortable temperature all year round.

  • Price

Most attic fans are affordable and installation is not expensive. However, the accessories, materials, and installation products increase the prices. This includes siding, shingles, gable mounts, and roof mounted vents. It is very important to find a support area to install your attic fan. If you do not have one, then you might need to create one. 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.


  1. When to use attic fan?

You should use an attic fan when you leave the house in the mornings. During the day, the attic heats up, sometimes over 160°F and transfers to different parts of the house. Turning on a house fan will just circulate and recycle the hot air. This prevents sleep and becomes unbearable at times since the heat is trapped. The attic fan pushes the hot air outside during the day, which allows the cold air to come in. So, when you come back home the air is cool and fresh. Preferably, turn on the attic fan from 9am to 5pm. If you stay home during this time, make sure the fan is on at noon when the sun is at its highest and the weather is at its hottest.

  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 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!
