Considerations for Best Attic Fans in 2020

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 fan will require extra vents to blow in the fresh air as it exhausts hot air.

Build quality –

This is very important. Completely avoid attic fans that are 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.

Safety –

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.

Ease of installation –

One way to cut costs when buying an attic fan is to look for a fan that is easy to install. 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

Comfort –

This is an important aspect when choosing an attic fan. 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.

Price –

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 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 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 noiseless 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.

FAQs on Best Attic Fans in 2020

How to install a solar attic fan?

Installing a solar attic is very easy because it requires no wiring. If you have the tools and the basic skills, this is how to install a solar attic fan.

  1. Choose the right fan – A solar attic fan is good for a gable roof. It is a versatile fan. Ensure that the kits are complete
  2. Find out the installation angle – It is better to install an attic fan facing the south. It depends on the roof. Connect the wiring to the thermal box underneath the solar panel after determining the installation angle.
  3. Connect the wires properly and tighten the connector – The water-tight connector is useful outside the terminal box to stop moisture. Open the 14-gauge wire and run it through the junction box opening. Connect the positive to the positive terminal and the negative to the negative terminal.
  4. Find the rafter and drill the brackets – Next is to find the rafter and drill the brackets. The panel should be held properly to the roof using the Z-bracket mounts that were drilled into the rafters
  5. Run and secure the cable – Run the electrical cable straight from the panel along the roofline to where the fan is.
  6. Measure the brace and cut it – As the solar panel is already in place, next is to install the attic fan. Measure and cut a 2x4 brace. Try to use a screwdriver to secure the brace inside the gable opening
  7. Connect the wires – Secure the brace. Take the 14-gauge cable that was run through the opening and connect it to the fan wires. Don’t forget to run positive wires against positive wires and negative wires against negative wires.
  8. Add the thermostat – Add the temperature controller. Make a good plastic electrical box to an area close to the fan. Connect one wire that comes with the controller to the panel wiring and connect the other wire to the fan wiring. Secure the thermostat right inside the electrical box and set the right temperature to activate the fan.

How to use an attic fan?

If you want to get the most out of your attic, this is a good guide on how to use an attic fan

  4. After the air is cool, you can then close the windows and blinds to keep the cool air inside the home environment.

How to wire an attic fan?

An attic fan is ideal for cooling off the attic when the sun builds up heat in the attic space. Cooling the attic area can have a trickle-down effect on your building by cooling your home environment.

After installing the attic fan, there is a need to connect it to a power outlet that is very close to the fan. An attic fan is usually controlled by a thermostat. It is the thermostat that triggers the fan when it reaches a certain temperature and turns off automatically when the temperature drops. Here is how to wire an attic fan.

  1. Turn off power from the circuit breaker - One easy way of wiring an attic fan is to connect it to an electrical outlet or an available junction box. First thing is to turn off electricity from the circuit breaker. If you are not too sure, use a voltmeter.
  2. Unscrew the outlet and remove it - Unscrew the faceplate held to the outlet using a screwdriver. Once that is done, remove the faceplate from the box.
  3. Connect the wire to the outlet - Run one end of the wire through the back of the electrical box. Get a wire stripper to remove an inch of the insulation on the green, black and white wires. Connect the white wire to a silver terminal on the outlet. Connect the green wire to the green screw and black to the bronze.
  4. Replace the outlet - After connecting the wire to the outlet, ensure it is inserted back to the electrical box. Secure the wire with the screws that were removed. Ensure the wires are straight and not curled into the back of the electrical box and set the faceplate to the outlet.
  5. Now, run the wire to the attic fan - Run the wire from the box through the attic to the fan. If you have uncovered wire, you will have staple the wire to the floor joists. But if the wire is covered, you will have to remove a part of the drywall to run wire through the studs.
  6. Connect a wire to the attic fan - Again, use the wire stripper to remove an inch of the insulation of the wire just as you need to the three strands of the wire at the other end. Connect the white wire to the silver, black wire to the bronze and the green wire to the green wire. Ensure that the connection is very tight.
  7. Cover the wire end - Use the cover on the back of the attic fan to prevent moisture and sparks.
  8. Turn on power to run the fan - After completing the installation, you can turn on power from the circuit breaker. Set the thermostat to your desired temperature and ensure the fan works perfectly.

How to replace the attic fan motor?

Replacing an attic fan motor can be very challenging since it involves wiring. But it can be done following this process.

  1. Remove the attic fan motor - The very first thing to do is to turn off the fan and unplug it. You may have to remove the attic fan completely and bring it down. But that won't be necessary if you can reach the back of the fan. The motor can easily be removed without removing the fan. Take off the back of the attic fan and remove the motor by removing the wire. Take note of where each wire belongs.
  2. Mount the new motor - Place the new motor into the attic fan. Fix the different wires into their rightful positions using a pair of pliers. Screw the connection back to the attic fan motor tightly and secure the wire with tapes. Then, return the back cover of the fan.
  3. Turn on the fan - Plug back the attic fan and turn it on.
