Buying Guide for Best Attic Fans

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”.

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 gears. 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 cost 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 enquiries 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 fan 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 make it 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.

Few Important FAQs Best Attic Fans

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 2×4 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.

I am Dennis Grubb with yellow blue
Ecotec technologies here today to show
you some of the features of benefits of
our revolutionary new solar-powered
attic fan the first thing I’m going to
do is go over some of the features and
benefits of the system and then after
that we’re going to go ahead and install
the system from A to C so let’s get
started the first feature that I’d like
to talk about is our proprietary
polycrystalline solar panel it’s
designed specifically for this
application it has very high light
penetration it’s weatherproof in the
most severe conditions there’s no need
to adjust the angle of this all the
solar panel do try to install the system
on the south-facing portion of the roof
but it will still work fine on the east
north or west portion of the roof the
next part of the system that I’d like to
talk about is the base and the internal
components made out of aircraft-grade
spun aluminum powder coated for increase
of weather resistance and beauty there’s
no need to worry about rust or expansion
issues and diverse weather because there
are no seams there are no plastic parts
to fail in high temperature areas high
ultraviolet areas or during a fire the
next part of the system that I’d like to
talk about is an internal air diversion
calendar but this is is an air diverting
cowling that takes the air that’s coming
up out of the attic is being blown by
the fan and diverts it in a smooth curve
so that exits out the system very
efficiently another very important
feature of the system is the motor it’s
a high performance proprietary brushless
DC motor it has a built in vibration
isolation system with a computer chip
built inside of the motor that will
harvest more energy out of the solar
panel another feature that’s not a bit
of on any
in the world last speech I’d like to
talk to you about is the fan blades and
pre balanced with the motor so in the
factory were dynamically balancing the
fan blades with the motor that makes the
system last a lot longer because not
putting extra stress on the bearings it
also eliminates vibration that’s being
transmitted into the house it’s
important features like everyone out
there to remember this is an American
engineer an American manufacturing
product I’m going to go ahead and go out
now and do the installation from A to Z
and they should answer all your
questions on how the system should be
installed tools needed to install the
yellow/blue Ecotec solar power attic
ventilation system sawzall high
performance drum motor safety gloves
caulking gun roof and flashing sealant
half inch spade bit common screwdriver
philips screwdriver utility knife tape
measure hammer flat bar or wunderbar
construction pencil two inch screw and
safety goggles okay this is our mock-up
that we’re going to use with the
installation demo today first thing
we’re going to do is we’re going to go
inside of the attic I’m going to show
you a technique that can be used by
placing a screw through the center of
the rafters there’s another technique
you can use by using a stud finder
finding out what the trusses are some of
the more experienced installers can find
that the spaces between the trusses just
by simply walking on the roof we’ve
determined it’s going to go into this
Bay so the first thing I’m going to do
is I’m going to put my tape measure up
to the top of the ridge I’m going to
find my 24 inch mark then I’m going to
go and measure between the two trusses
about 10 inches in the center mark an X
here then I’m going to take my screw we
want to place the screw and drill it
directly through the the plywood through
the roofing material so that it’s
exposed up on the roof you can see here
now we’re going to place the template
that’s included inside of your kit over
the screw and then the purpose of that
is so that we can then take your
construction pencil and Mark onto the
roof around the circumference on the
template and you’ll have a perfect guide
so that you’ll know where to cut the
hole with your sawzall
okay after you’ve made your mark as you
can see here around the template now
you’re going to take your half inch
panel bit you’re going to place the half
inch paddle pin directly on your line
and then you’re going to drill a hole
through the roofing material and the
plywood below it that’s going to be a
starter hole for your Sol’s off we’ve
made our pilot hole now it’s time to cut
the hole through the roof use the sharp
blade when you cut that and do a neat
job when cutting through the shingles or
whatever roofing material you’re cutting
one of the reasons why we place the
screw in here is not only for placement
about the template on top but it’s also
a place that the Installer can hold the
slug when it’s being removed because
it’s very important not to drop this
down into the Attic because it hits the
drywall and could break through into the
house causing a very expensive repair so
be sure not to drop this okay the next
step is we’re going to take our flat bar
and we’re going to lift up the shingle
around here and the reason for doing
that is so that we can make sure that
the flashing is gonna be able to slide
back there are about four and a half
inches and this step we’re going to take
the sawzall we’re going to place a blade
at the saws-all underneath the tar paper
between the tar paper and the roofing
material and we’re going to make a
circle and what that I’ll do is I’ll cut
any nails it might be in the weights of
the flashing will slide underneath there
for the shank oh stop the tarp ever
begins we’d like to get the flashing
underneath the tar paper and reach in
here and cut back about four and a half
inches it’s not always necessary to get
the flashing under the tar paper
different rippers have different ideas
and thoughts on how that should be done
I’m gonna recommend it that it gets
installed underneath the tar paper yeah
for the whole city crap we’re going to
write the flashing in and do it until
it’s right fit so we put it underneath
the shingles I’m going to go ahead and
pull it off now I’m gonna place some
Cena underneath the bottom of the fog
the solar fan and place it back on into
the shingles and then we’ll fasten it
down okay now we’re going to apply two
concentric beads of roof sealant around
the bottom of this flash and one of them
is going to be approximately here and
the other beads going to be here don’t
put it too close to the inside of the
flash and keep it close to the outside
what this will do this will help to
ensure that the unit will be held to the
roof a little bit tighter as well as
keep any possible leaks that might be
coming in up above the flashing
fiz I’m after I’ve applied this sealant
to the bottom of the flashing and you
can place it over the hole but I have to
hold it up so that only end up wiping
all the sealant mom
okay now we’ve placed the saw pen on the
roof the sealant is under here we have
it straight and level now we’re going to
place the screws we recommend two screws
on the bottom two screws on the side two
screws on the back
okay after you’ve installed all the
screws around the solar fan you can go
ahead and put a bead of caulk all who
run the neck very important to get it
around the back on the top of the screws
that we placed in this case so that this
looks nice I’m going to place a bit of
sealant here and I’m going to put this
small piece of gripping material back
I’d like it to look nice
okay the installation is now complete
I’ve applied a bead of sealant around
the outside neck of the flashing just to
make sure we don’t have any leaks
the sun is shining the solar-powered
attic fan is operational and the
installation is not complete
we’ve hope that you’ve enjoyed this

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

  1. Switch the fan on to the highest setting so that the fan can boot properly. Immediately it starts to boot, the slats will open up and circulate air
  2. After booting, you can switch the fan to the setting that you desire
  3. It makes sense to run the fan when the temperature is cold. The best time should be at night or early in the morning
  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 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 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 was 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 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.

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.

How to Replace an Attic Fan?

Video transcript:

So our attic fan broke because we had a
sloppy contractor who got something
caught in the fan and so today I’m going
to show you how to replace the motor of
an attic fan so first thing you need to
do is get a replacement motor and these
can be sourced online but you need to
make sure you have the right part and
I’ll have a link down here for where I
got mine where get yours I have a light
because I’m gonna have to turn the power off
wd-40 handy Leatherman and a socket
wrench and that should be all we need to
replace this so first step with any
electrical job is I’m going to shut the
power off which is why we need these
lights so the power is now often the
first step is going to be taking the lid
off the adjustable thermostat typically
these just pull right off there it goes
okay and now we want to connect the
electrical so what we can see in here is
electrical running to the fan you can
see a black wire black wire and a white
wire so we want to leave everything else
intact we’re going to take out the black
one that’s running to the fan and to the
white one running to the fan okay so
these have been removed and the next
step is going to be to remove the
conduit I restarted here but you’re just
going to twist this part right there
counterclockwise until it comes off and
you’ll see just as I’m screwing this so
I’m going to do that and then I’m going
to get my wrench and there’s a couple
screws that hold this in one’s right
here we’re to unscrew those three screws
and hopefully then the motor will just
pop right out and it should pull right
out from the electrical okay so those
are all loose and now this whole unit is legion what’s
homemade it is the fan blade and so well
this actually might be great now using
an iPhone you can see the little screw
holding into place I’m going to unscrew
that and then this unit will be free and
we’ll swap the other one out so the
little screw up there was a hex screw um
so I needed a hex key to get it out and
luckily I had one but it’s still really
really tight so what I did is I came in
in here and sprayed a little wd-40 on
that sucker let me give her a minute and
try to loosen it up again but once we
get that off the whole unit should come
out and we’ll swap them out so this is
the old fan you can see it’s made by
venom addict limited and so I have a
replacement here this is the replacement
model I’ll show you where you can buy
this I’m going to do a swap off this
part here cover it up here and replace
everything just so you can see it really
was hard to get off but there’s a little
hex key piece that holds the whole thing
together so I’m gonna now do everything
in Reverse and hopefully it all works
when we put it back so everything’s now
back together and I can power on it
switching hollowed-out unscrewing that
little screw on couple fan replacing it
tidying everything back up and as I
thought the thermostat wasn’t what
yeah what worked out so hope this is helpful once
again I think the key thing is making
sure you find the right for placement
motor and once you have that it’s not
comparable good luck placing your attic fan.
