This is how i installed my gable end attic fan. I bought it from Lowe’s/Home Depot on sale and put it in my attic to try and cool it down in the summer, because our upstairs was getting too hot. It was cheaper than running my AC constantly. Also i wired in an override on/off switch and a pilot override switch to control the thermostat on the fan.

Your the first guy who covered the electrical connect in detail unlike the the other vids I've watched.
Great video 👍
Thank you for not editing out your mistake. Makes the installation that us regular guys can do also.
Good plan. We moved the fan thermostat from the fan over to the crawl space area and hung a decent thermometer next to the mounting position close to the crawl space for attic temp reference. This helps by not having to go up into the attic and adjust the thermostat at the gable. Big help. We set the turn on temp for 110 and that seems to work best so it doesn't run all night long. Typically it turns off around 9 pm on a warm evening and on around 1 pm on a hot day. We lower our living space temps by 10 degrees by having an attic fan with our single story ranch home. One other feature we installed was a maximum temperature shut off which turns off the power in the event temps rise above 200, in case of a fire, it won't run and feed fresh air to the flames. We also wired the thermostat with a pilot light switch which was mounted on the wall near the ceiling just below the crawl space which is located in the hallway to bedrooms. This allows for a master on/off for personal needs as well as for maintenance needs.
Glad you mentioned the fire issue and potential for feeding oxygen to an attic fire. How does the max temp shutoff work? Thank you.
@@KD-mj2ms There is a high temp shut off in the thermostat that enables at a permanent set temp, not sure of the setting temp but it will turn off.
Dude, I LOVED this video, the bat and the multiple trip and the screw ups!!! Priceless and feels like ALL of my home improvement projects.
We have a new roof with black shingles now so I think this will help. Thanks for this video.. very humble and honest. I appreciate that..
One of the tricks I learned is that the fan should be sealed around the opening or else it tends to just pull in air from the outside and recycle it instead of pulling from the attic. You also need a vent at the other end of the attic (or in the soffits) so it pulls the air across the whole space. Good luck!
I was going to ask about an intake vent but you answered the question thank you. I will also put a vent in a lower outside door to allow air to be drawn in at night.
Work in attics at night. Thanks for showing how to do this! Welcome to the Machine!
I just finished doing mine and I made sure to seal any air leaks around the fan with tape and sealant. Made a difference for sure but it is still hot up there. I should probably have done a before and after temperature reading.
Wow, your work bench is so organized!
This video had me laughing , least you owned up to your mistakes. Did electric work with a friend of mine in a similar attic in July last year. Amazing how hot these kind of attics get.
I lately install a attic fan 1900 fmc. Before I install attic fan which was 140f. Downstairs was 95f. After install one. Amazing Changed. Downstairs is 75-80 f at most time. Great investment to install one
Really liked your video. Including the errors is appreciated. You have learned from your own mistakes and by sharing that, we can learn from them, too. Thank you, sir
Installed today thank you very much!!!
Awesome. First search got what I needed. I have in my garage and wanted to have switch access for when I weld to pull out the smoke. Excellent 👌🏼
any improvement in the cooling of your home?
Thanks
62c in the attic?! I didn't know the gateway to hell was through your attic. That's frikkin hot!
You're awesome. I enjoyed watching this video. Informative
Don't feel bad about the wiring mistake. When I bought my house the only way the smoke alarm would work was if the hall light was on. Yep, the builder hooked the smoke alarm to a hall light switch. Against code but they got away with it. I disconnected the electric smoke detector and put in a battery powered.
So, the big question is, how much cooler did it make both your attic and you r upstairs portion of the house?
Good
I am suggesting getting thicker insulation in your attic for your A/C problem. My new attic fan barely made a difference, but once I installed R-49 in the attic. My interior problems were no more.
This system works guys
Nice job
What was the temperature in the attic after the fan installation?
Liked the video! But word of advice don't trust that widow maker, the volt stick 👍🏻
I heard you, I was telling my helper the same thing, those things will beep sometimes when there is no power running through and they will also behave the other way around
So I might wire it a little differently but wanted to thank you so much for the switch suggestion.
good video, but you should warn viewers when you're showing your wiring with the switch to the fan/thermostat switch legs that 120 volts A/C can KILL them with even a momentary contact with the energized circuit if the current hits them just right! ( a 50 milli-amp current across the heart can put a person's heart into 'fibrillation' which will require a defibrillator to restore the heart rhythm)
How much of a difference would you say this makes for you during the summer?
The goal was to cool the attic from 130 degrees to like 100 in the summer, so that the AC wouldn't have to constantly run.
Ideally there would be lots of air-flow from the outside.
Not sure about the difference it made, since one day it would be 90 degrees outside, then the next it was 80 degrees.
But i'm sure it helped somewhat to lower the attic temp. But i can't say that it immediately dropped the temperature 30 degrees or something, i never checked.
I did this with a 17$ 12 inch 3 watt fan that you find in computer section at Fry's with a small solar panel that gives 3 watts for like 30 $ and man that thing makes a world of a difference
A 12" inch fan in the computer section??? Wow.
Yeah they have them I didn't know they made them that size but they do
I know this was a few years ago, but was there any update to this on how much, if any, it helped?
good work
Job done. You're alive. All good. Attic fans are good but WAY too small as a whole house exhaust fan. A fan specifically designed to move the necessary volume of air is required.
where does the black tripple wire cable come from? I am assuming that is coming from the breaker. I think a step by step installation would be helpful.
An effectiveness test would be interesting.
The problem with having a black wire or the hot wire running to the fan and the switch controlling the neutral or the white wire is that if it grounds out somehow it's going to turn on or in layman's terms it's going to have power to it 24/7 so even if you turn off that switch and you have a hot going to it that's uncontrolled it will still electrocute you with that light switch off
Will the fan motor last longer if it turns off now and then according to temperature or one that runs 24/7 nonstop? Thanks for the help.
If it's a motor with contact brushes it's going to wear out faster running it 24/7, not to mention the additional cost of powering it non-stop.
if you put a small shroud around the fan, wouldn't it help draw in more air through it instead of just having it free hanging?
Paralleling a manual switch with a stat is ok.Switching a neutral wire is against code.
I have the same issue ? How many degrees reduce after the installation?
Ok... u installed it
Did u check the temp in attic afterwards?!
How much
Did it lower the temp?
Did it work. Did the temp go down from 140?
Very good, good job, if the attic wasn't that hot you would do the job faster, but good video, thank you, i am going to do same thing soon.
Let's assume that the bats get into your attic thru that vent. By putting up the screen in the daylight hours you have trapped any other bats inside the attic to die. Better idea would be to put up the screen at night when the bat are outside. Then when the come back in the morning they can't get back into your attic. Then you start the other work. Oh, yes. Did the fan cool the attic?
Yes doing it at night would be the best way. Or i've seen where you can make a 1-way tube or something where the bats can get out but not back in. But i only had free time during the day. Night would have also been a lot cooler up there too. And yes the fan helped i think. But i didn't really do any testing to check the temperatures with the fan off or on, so i don't really know.
thank you for sharing the one you made mistakes, so we dont have go through for that, Gbu👍🙏
What was the outcome for the temperature in the attic?
Yeah I'm wondering the same thing... did this help cool the upstairs?
Beau S, I'd like to know the answer to this too.
So far this summer we've had a couple days in the high 80's, the upstairs does seem cooler. It's not unbearably hot like last year. But to give you a definitive answer i'd have to go up to the attic on a day when it's 90 degrees and see if it's still 143 degrees. That's not really something on the top of my to-do list.
I am wondering the same thing, what was the temp in the attic on hot days after install?
please do it. because we want to know if it really works. My house attic is the same set up as yours, so I am doing lots of research to see which way is the least expensive and yet works well. Thank you
My 2nd floor used to be an oven in summer and one room was cold in winter....found out our attic had a out 6inches of insulation had company put new insulation to 17inches problem solved 2nd floor improved 95% not an oven anymore nor cold in that 1 room, air and heater working less, saving money on both....no need for fans...also read fans screw up cooling system of your air conditioning
The ADT alarm guy almost had heat stroke installing wiring for cameras in my attic.I probly need an attic.
smoke detectors are great places for constant power
Except if they've got an interconnected 3-wire circuit.
Depending on the power draw, if too large of a voltage/amperage drop occurs, you'll make them all go haywire at once.
You could of just made a jumper from the rooms power from that switch. Either way good video.
Hi just have a question regarding installing a roof fan like u did on a residention roof that currently has 4 other vents on roof.....what do u do with the other vents? I was told you would plug them up but not sure i agree with it........if you plug up the other vents where is the air going to go when fan is not running?....any input?
Well i had a gable end vent on the other side of the house. I was hoping to draw air in from the other side and cool the attic down.
IMPORTANT!! I've got a much better/cheaper system, for your over heated attic! I've studied this kind of situation (being involved in home construction, most of my life) with the dredded hot attic effect, which also eventually heats up the rooms in the house, and also reduces the shingle life, with the sun bearing down, trapped in your attic year after year!
If your determined to use a ''little'' gable wall attic fan, which isn't moving much air, even if your doing everything else correctly! You should then close off your roof vents and open up soffit vents in the lower soffit eaves, to draw cool, outside air, up from the lower part of the attic which then travels up through the attic, allowing (chimney effect) naturally drawing heat up, and out your fan vent, and will work 24/7 even with fan off, or with no fan at all! You have a But not your most efficient system, sorry to say! Possibly the least efficient/cost effective, when considering several, much better/cheaper way!
Your best way to draw heat out of the attic and ''without 'the need of a fan'', is by opening soffit/eave vents up, allowing heat to be naturally to be drawn up and out roof vents/attic gable vent! No fan needed.
The very best system, is ridge vents! Their the best way to expel the most heat volume, with soffit vents open!
Your not drawing heat out, if there's still heat, trapped (vacuumed) in your roof, that's not moving! It's only drawing cool air in through the upper part of the roof, through your roof vents (if you have roof vents) which are located at the top of the roof, leaving the heat still trapped deep down, in the roof area, and at your attic floor, which is conducting the heat down through the ceiling of the house, which is then eventually heating your living space, towards the mid part of the day, on into the night!
Think of it the way your going about it, in simpler terms. Like drinking from a straw. By poking a hole in the middle of a straw (think of it as where your upper roof vents are) then try to draw liquid from your glass, it wont! It only draws through the hole we made in the straw (which would represent where the location of where your upper roof vents are) since it's the closest opening of the draw! Now think of it doing the same thing in your attic drawing cool air in from the top of your attic leaving the heat below this point, unable to move trapped heat in your attic and then eventually conducting heat down into the roomes of your house, and melting your shingles! The more you think of it, the more it makes since!
thank you...my house never had soffit vents..i added soffit vents a few yeara ago....so what i have currently is about 16 soffit vents open...i have 2 roof vents and 2 gable vents and 1 roof mounted fan....i have the gable vents and roof vents blockked off...i was instructed to do that if i installed a power roof fan......is that ok? ...and fyi...when the roof power fan is not running how can you say 1 roof power fan vent would suppley same air exit as my other vents?...
Updates??!
How loud is the fan? Did it work in reducing the upstairs temperature?
The fan was super quiet. We at least in the house. You really couldn't hear when it was on. And ya, it could have been better but it did blow all the hot air out of the attic and help to cool it down.
What was the temperature in the attic after installing?
same he should of done a thermostat after the fan has been running a while.
I wanted to know how much difference it could make watched through the entire video to not get any
You will still have to go up there at least once a year to oil the fan motor. I noticed that motor still had an oil port so it is not permanently lubricated.
You should be lubricating it anyway. That basic maintenance of any machine.
is wd 40 ok for lubrication?
Attics are much cooler at night to work in if you have a choice.
Hope you dont get a leak as water into those boxes you installed in closet ceiling is accident waiting to happen
I have only watched the video once through. Question: It appeared that your attic had minimal insulation and that there were numerous air leaks from the climate controlled living space up into the attic. If I am correct, that attic needs to be air sealed and insulated immediately. Sealing the living space "envelope" is really important.
Do you have air conditioning installed in this house? Does the power attic ventilator (PAV) run even when the A/C runs? HVAC experts are adamant about never running a PAV at the same time that the A/C is running - due to the PAV pulling a lot of conditioned air up and out of the attic. And they are adamant about that rule - even when the attic is properly air sealed - so that air infiltration is minimized.
Yes your right he would have been way better off sealing the leaks in his living space and bringing his attic insulation up to code or better. Professionals in the field claim that attic fans are not a cost-saving investment.May 31, 2017
Finally someone that gets it! Attic fans are a bandaid at best in most cases.
The attic has got to be properly sealed and insulated for this to have any real chance at making more than a 10°F difference.
Most houses with R-38 or better and a properly placed/sized whole house fan do amazingly well without an attic fan.
Pink Floyd machine nice
This may sound duh, but make sure your fan is pulling the air out to the south or west side of the house.
Def bring 1-2 box fan with you up in the attic, while you're working, BIG DIFFERENCE when working
How much electricity it cost you per month?
At 4:45, it’s 144.3*......not 143*. I think the heat was getting to him.
thanks for the video but you didn't show any results. How drastically the temp change.
It's hard to tell. I haven't really gone back up there in a while. I only know that when it's a hot day and i hear the fan on in the attic, i know it's over 110 degrees which is what i set the thermostat to. The only way i think i could test it is if say there were 2 days in a row around 90 degrees, the first day turn the fan off then go up at 5pm and check the average temp. Then the next day turn the fan on then go up at the same time and recheck the temperatures. I just think that our attic didn't get a lot of airflow so anything like fans or baffles will help blow that hot air out of there.
How good did it work was it worth it?
zay c I think so. I can hear the fan turn on during hot days. Hard to tell how much its helping though.
UpDate???
you sound like an intelligent fellow so why is it that you wait for the temps to reach 90 outside before you start? Get up at 6AM and start, then you can finish before it gets to 80. I see later on you came to the same conclusion. good luck with your fan.
It woukd be easier to use a wemo wifi socket switch you can control using your ipad.
Dang good , 4 stars
Is the fan still doing the job for you?
We don't live there any more. But yes it helped blow out the hundred degree air from the attic. But a whole house fan would have worked better i think.
Good but u forgot to mention the most impt part/reason we all listened to u. DID IT VOOL THE ATTIC???????
Make shore your vents and eves are not covered with insulation and you need much more information and a vapor Barrier! Your conditioned air is flying right out
Everyone have mistake .
Fan wastes over half its effort pushing against the vent louvers-ask me how I know
only thing I can say if he had bats there , putting wire on inside will still allow them to get in he needs to seal off from outside.. bat poop is not good
80F is hot?! What?!
Man i have the same problem. the attic is around 150 so AC doesn't stop or cool. morons only put one fan and it stopped working years ago. TU
Why are you doing this when it is so hot?
The same reason why i climb up on a ladder to unclog leaves in my gutter during a rain storm.
And you didn’t test the attic temperature after the fan is installed? I watched the whole video just for that!!! 😫
This is a how to video, I have several questions and concerns. Your video is very misleading and could get other into deep trouble. As an example, some homeowners insurance policies strictly prohibit the homeowner from doing electrical work on their homes, better check with your agent as if anything happens to your home you could find yourself not covered. In most if not all cases an electrical permit is required even if you as a homeowner are permitted to do the work without being a licenced electrician. Better to be safe than sorry.
Was the picture at 6:51 the final completion/ connection at the fan unit ? Did you connect the grounding conductor to the devices ? What was the load of the existing circuit you acquired power from to determine if it was adequate to support the new fan unit, the system looked older so there maybe too much on the existing circuit already ? I noticed crimp sleeves "used for connecting ground wires" in your video, did you use the proper amount of twist and correct tools to connect them ? Did you properly support and protect the wiring "romex / nmb in the attic area were required ? There appears to many possible issues with your installation that does not meet basic electrical code requirements. Did you pull the required electrical permit for the added wiring and have it inspected ?
Just asking.. I'm not trying to be an ass but if you're going to teach, be ready for constructive criticism, especially when it comes to fire, life safety issues.
Robert De La Cruz best reply of 2017...right on
Robert De La Cruz blah blah blah
Stick your criticism up your Ass
Deplorable Pat he is looking out for the guy but this comment made me lol
Why don' buy the solar is cost about $ 80 and it run by itself.
JIMMY TRAN - Because they’re crap and do literally nothing.
I've been there. you can barely get the electric tape to stick your hands are so wet.
If you do it the right way you dont use electrical tape just wire nuts
You showed the temp...with your thermometer. ..show the proof that this even works...
Call an electrician!
No te entiendo habla espsñol.
Yeah you need to get back up there and put those wires in a box 6:50 . You know I like your work but this is pretty sloppy.
That is Hardware cloth... look for Bat POOP... if you do, it can be dangerous to your family. Call your insurance company.
Seems like a reasonable idea. I probably would have used a square piece of plywood and cut a round opening in it. The plywood would have sealed off the opening.
Not good installation, if gets hot no way yo control from switch you have to cut the power during night time
The fan will not make even 1 degree F of difference.. nada,... nothing ... it’s still 140F guaranteed.
It does not...
You do a lot of talking, but not a lot of showing you doing the work. Sort of half a video.
This what keeps us busy, homeowners failing at work they attempt. Just another TH-cam wanna bee. Install a operable louver, that vent and fan are very inefficient, no one should take this mans advice in this "instructional video"!!! Especially the electric work. Please reconsider what you post.
Its been six years, so how has it been doing? I need to see a comment please? Thx
any improvement in the cooling of your home?
Thanks
