Just installed mine on the gable vent, and used the black plastic shroud to seal around the fan. I still have some blow by, so I'm going to use some foil tape just like you to seal it. Good idea!
after checking prior to installation the ambient heat on the interior ceiling is 20deg cooler than the attic. Plus the other consideration of installing attic/gable fans is it increases the length of life on the shingle tiles. I love the App so I can adjust fan speed and temperature settings.
I just installed two 2.0 fans. Love em! Good choice.
How is it working out? I'm thinking of doing the same thing on my house since it has a gable vent at each end of the attic
Did it work
If the attic not that super big, do not use qty 2 fans. Even the logic to move hot air as fast as possible, if 2 powerfull fan run at the same time and not enough supply air, it will create attic vaccum and will draw air from inside house (air leaking from cables, light can, etc)
Great video very informative thank you very much
Very helpful. Thinking/planning on install of similar unit at home. The ac units in our house do not bring in enough fresh outside air. This unit once installed and operated as instructed should be a big help. Thank you.
Attic fans don't bring in air to your living space. Whole house fans do. Attic fans strictly help ventilate your attic to cool it and help with moisture issues as well.
I added an attic fan to my house. My gable end vents are 2ft by 3ft. The outside air temp in the day is 117F, at 70% humidity, and 75F at night. Before adding the fan, when the outside temp was 96, the attic air was 160. We have 60,000btu of cooling for a 1000 sqft house. The Living room temp was 78F.
After the fan the living room temp was 68F, and the AC sometimes turned off, even with the outside air temp 20 degrees hotter. My guess is that the attic air temp is about 15 degrees hotter than ambient instead of 75 degrees hotter than ambient.
The person who built our house put the rafters 24 inches apart, or 26 inches on center. There are fiberglass batts, which leave a 2 inch gap next to each rafter through which I can see the clean top of the sheet rock. When it isn't 120 degrees in the attic during the day I am going to add some blown in insulation.
oh yeah, I used the circuit with the microwave oven, so now I can't used the microwave until I rewire it. Now using the microwave blows the circuit breaker. The fan I used is about 250 watts. There was already a gable end fan tucked in the corner of the attic not connected to anything, so I used that one.
Want to double its efficiency and dip the temp even lower? Add another attic fan to the opposite gable that is pulling in outside air which then created a flow of air that is then sent outside. The goal is to make your attic the same temperature that it is outside
I actually added another fan to the opposite gable, so I have two fans, pulling the air from the attic to the outside. I don’t know if you would want to blow air into the attic I think it would be better to have both fans drawing air out of the attic.
I just finished a video on the subject of having two fans ruclips.net/video/p0yCDhB92io/видео.htmlsi=RXwuoaBDzsy5VEYn
We installed the tamarack whole house fan this past winter, it works fantastic, providing the outside temperature is less than the house. We think it takes longer for the attic to heat up the next day. We also have a gable fan. It's our 2nd one, in 20 years, it's not a qc fan.
QuietCool AFG SMT ES 3.0 installed.
Fan works fine, except when the temp inside the attic increases quickly when the fan is on.
It will jump 5 degrees in 5 minutes after I start running the fan. Its April 2nd, not hot yet and the system is increasing my attic temp.
It’s very possible the other side of your attic is the hotter side and then when you turn the fan on you pull the hot air from the other side to the cool side. I just installed a second fan on the opposite side of the house and it really helped.
@Paul Frank thanks Paul. I creeps up 5° total but thats all. I guess I'm just expecting it to only go down
21 watts jajajaja wow amazing
Thanks for for video - I'd like to know about vibration that occurs when you run the fan on the various speeds? I've got a security camera a few feet below my gable on the outside of my house - the power runs through the attic to power it. Concerned there might be a interference or wire issues to the camera if the vibration is too strong? Thanks!
I believe quite cool give vibration pad with purchase, if not, just get vibration pads from amazon or local store. Rubberized pad or cork pad type
I’m thinking a bout doing an intake on the south gable and exhaust on the the north gable(or the other way around. Also splice both fans into one control module. Do you know if the controls are low voltage controls and would this design idea even be a good/efficient way to use these fans? Thanks in advance for your time and feedback
I would set up both gable fans for exhaust Only unless you have no soffit vents. Then put one fan on the hot side of the house. Make sure you have enough soffit vents to draw from if you use two fans. Make sure you have your living space sealed so you don’t pull air conditioned air into the attic from too much pressure from having two fans. I would not connect the fans to the same control module because almost always my fans run at separate speeds because one end of my house is usually 10 degrees hotter than the other so one gable fan is usually at a higher speed than the cooler side of the house.
Great video. I just installed two of these fans on each gable end of my 1500 sf house. You might think this is overkill but if I keep both fans on medium I'm pushing over 4000 cfm at 150 watts. That's slightly higher wattage than one fan on high but it's moving 33% more air. Air turnover is key on these fans. How many minutes does it take to turnover the air in your attic? The shorter time the better because you are fighting the incredible amount of stored radiant heat from your roof and all the structure in your attic on hot, sunny, summer days. Make sure you have the proper amount of intake vents in your attic or you might create a vacuum and end up sucking conditioned air from your living space and run the risk of CO poisoning. Not good.
I would like to install, a 2nd quiet cool attic, fan. For the same reasons. My plan is to run both fans on low. That's 2600 cfm. 30% more than the med speed, of 2000 cfm. On low both fans would cost me .014 cents per hour, half what it would cost to run one fan on medium speed. Question, can I operate both fans with one phone?
If your pulling air from inside home. Your home needs to be air sealed.
I just did a video of why two fans are very beneficial. ruclips.net/video/p0yCDhB92io/видео.htmlsi=RXwuoaBDzsy5VEYn
Update: I just installed another fan for the gable vent on the other side of the house. I’m glad I did it because my first fan was installed on the cooler side of the house and was pulling the heat from the hot side to the cooler side of the house. This is because I had the first fan installed opposite the setting sun side of the house which is definitely the hottest in the evening.
Now each fan runs less and I pull more hot air out of the attic. I’m not sure if it’s going to really save me much over just having one fan but it definitely removes more hot out of the attic. Advice up to this point: if you’re going to have one fan definitely put it on the side of the house where you have the evening sun. Make sure you have enough venting to support two fans. For full benefit have proper attic insulation, seal the ceiling for leaks to prevent attic leaks (This is called the chimney effect if you wanna look it up), add radiant barrier, and proper attic ventilation.
With the 2 fans exhausting the hot, attic. Do you you notice any difference, in, the temperature inside the home, in otherwords. Did you have radiating heat from the ceiling, and now you dont
When dealing with heated, or cooled space. Always think passive, let heat rise and do the work for you, all we need to do is help the heat move along faster. Just like you did with,the first fan, you should always exhaust toward the hot side, let that heated wall carry the exhausted hot air up and away
@@markchristensen5206 It’s too soon to tell. My impression is that I probably was doing a poor job of pulling the air it was really hot from the other side of the house. I guess for a couple of days I could turn the New fan off on the hot side of the house and see what the temperature rises to. Definitely the fan on the cooler side of the house runs less than it Did when it was the only fan. My guess is that the farther away I got from the cool side of the roof the more I was using passive heat rise then I was actually using the fan to expel the heat. Definitely adding a lot of insulation and sealing the house and the radiant barrier contribute a lot to the fact my air conditioner rarely runs.
Can you control both fans with one cell phone
@@markchristensen5206 Yes I open the app and then you choose which fan you want to control. It’s kind of nice to know the exact temperature on both sides of the house and control at what temperature each fan kicks on or off.
Hey Paul! Nice review. Was looking at the QC Attic fan specs on the Home Depot site.
Up to 2,830 CFM on high at 163-Watt
Down to 1,343 CFM at 22-Watts
If you are a DIY type, would putting in two of these give you approximately the same cooling efficacy on low (at a total of 44 watts) as one running on high at 163 watts?
I’m actually considering putting another efficiency QC fan in the other gable to do exactly what you suggested
keep in mind you need exterior,cfm, vents, that are greater than your attic fan cfm, is moving
Yes - ECM motors are more efficient at lower RPM. I used two of the fans reviewed in this video on my 1500 sf house when one fan is recommended for 4000 sf. I never put them on high to get the highest cfm per watt. They work great.
Hello Paul, thanks in advance for your important response! what is your 10 month review of actual impact inside the house? Has your air conditioning cost gone down, meaning you were able to measure cost perhaps?
I've got A $790 quote out the door for installation, including a power switch up in the attic and he has promised high quality professional results. He says the Bluetooth works fine, this particular size on low should easily move the volume of the attic several times per hour or something like that. I don't have the numbers with my fingertips.
QuietCool Smart AFR SMT ES-2.0 Smart Attic Fan, roof
Considering the amount of work to install these fans $790 is a very reasonable quote. Installing the fan correctly will definitely impact it’s ability to properly ventilate.
I’ve only had one good summer month so far to do any comparison. I went from 700 kWh per month to 603 kWh per month in the month of June. July was 1100kWh to 903 kWh. Most definitely I’ve noticed my AC kicks on later in the day and definitely runs a lot less. Earlier this spring additionally I added some insulation and sealed my attic space. Of the 4 Improvements I’ve made for cooling my attic by far the fan is the most effective. Adding the radiant barrier would be number 2 and insulation would be number 3.
Additionally because of the added ventilation my soffit vents need to be cleaned more often. I noticed my attic temperature rose to 15° above outside temperature and after I cleaned my soffit vents the temperature dropped back to only being 10° warmer than outside. Point being the fan is most effective with proper attic ventilation.
No doubt the fan has significantly contributed to decreasing my electric bill but the best savings will be decreasing the load on my AC unit which saves me in replacement costs.
@@paulfrank1777 Awesome. So helpful. I think $ payback will be awhile, but if it helps lower the inside temp, that's what you buy it for! In Riverside CA, get summer July - Sept highs of 90 - 105. I have evap cooler, use alot. But at night will run the A/C cuz sleeping. Some days humidity to too high for evap efficiency, so have to run A/C. Techie as myself. Math doesn't lie! Until you get to other dimensions, lol.
Nice, I just had an HVAC company quote me $4,500 for the same description you just gave. CRAZY! I'll just DIY.
@@RSchannel777 if your home is hot at night. sounds like your attic, doesn't have enough insulation, nor are all ceiling penetrations sealed. for your area I'd insulate to R76. I live near San jose
I noticed your radiant barrier installed also. It looks like it’s installed over insulation ? Planning something similar in conjunction with the gable and a whole home fan
The radiant barrier is not over any insulation on the roofline. You really need a gap to let the air escape and go up. Put on one area of my upper floor. I did have to put the radiant barrier right against the insulation so I didn’t attach it to the rafters.
I plan on using this fan in my garage. What is the sound level outside? Will it disturb garden living and neighbors?
I think they make a fan specific for the garage. You can hear it outside but it is not very noticeable.
Would you suggest putting one on both sides of my ranch-style home or just put one that way it can pull air from the other side?
That depends on a lot of factors. Might try installing one fan and see how much it draws from the other gable vent on the other side of the house. But most likely two fans on low would pull a lot more air than one fan on high. A better idea might be to install one whole house fan and then one gable fan.
@@paulfrank1777 Great, thanks for the advice!
gable attic fans are for day time use, whole house fans, are for the,interior of the,house, use during the cooler evening hours. now that, the gable fan can be controlled to run at anytime. the higher cfm volume, might assist the whole house fan,during the evening. I'm going to give it a try
I just finished another video on the subject. I hope this is helpful. ruclips.net/video/p0yCDhB92io/видео.htmlsi=RXwuoaBDzsy5VEYn
I need help. I have a large roof , only 1 gable vent . How can I pull the hot air from all areas inside the roof through 1 gable vent with the quiet cool vent ?
Do you have a roof vent on the other end of the house opposite the gable vent? Or you could possibly add another gable vent on the other side so you can pull from the top of the house. The main thing is to make sure all your soffit vents are clear and unobstructed with dirt and debris. I think good circulation is the key to the quiet cool adequately evacuating the heat.
@@paulfrank1777 I really appreciate you response. But it’s complicate the way the roof was built. Are you on Facebook or IG where I could possible send you pics ?
@@jasonali323 If you live in Oklahoma I would Would call QC oklahoma because they’re going to have a better idea than I would’ve exactly the best way to install the fan. I’m definitely not an expert in this area.
This video might be helpful. I just reviewed the two fan benefit. ruclips.net/video/p0yCDhB92io/видео.htmlsi=RXwuoaBDzsy5VEYn
How about outside We have a patio area below our gable
The amount of air draw from the gable vent is very very low. Probably only pulls enough to hold a Kleenex to the vent. So I wouldn’t think it would be very effective for that purpose alone.
I put a quiet cool whole house fan but I shut it off once it gets to hot should I buy a quiet cool gable fan like your showing here for when whole house fan is off?
It would definitely cool your attic in the hot summer months which would be a good idea. Especially if you have a second floor that is surrounded by the heat in the attic.
The whole house fan is designed to cool your home, by pulling outside cooler air into your home, why would you leave the fan on, longer, and raise the, temperature of your home. With all these different types of fans, the biggest thing we, can do, to keep the inside of our homes more comfortable, and lower the utility bill, is insulate the heck out of the attic, the R values that are stated for the different regions are a minimum, like R 60, dot be afraid to exceed them, i personally have gone to R 76, thats 2 layers of R 38, they criss-cross, I personally prefer the fiberglass type, it stays in place, the blown in insulation settles. And moves with the wind. The home is much cooler summer, warmer winter, the electric bill thanks me, those of you that want, the, what's my pay back, time frame, you cant think that way. the pay back, can't be figured, roof lasts longer, utilities don't go up as much . The biggest one is comfort, as we get older we don't like the heat, nor extremely cold.
Are you going to do an update video?
Not sure what I would do for an update video. After one summer it seems my savings have been between 100 and 200 kilowatt hours per month. It definitely keeps the air conditioner from running a lot at night. I’m thinking about getting another one and putting it on the gable on the opposite side of the house. But I’m not sure
@@paulfrank1777 how well insulated is the attic, and seal all ceiling penetrations
@@paulfrank1777 here's one more place to cut back on kwh, do you have bathroom fans, that are connected to the light switch, plus if your bathroom fan. is not a slow start fan, your wasting, big money. my old bath fans were the braun fans, loud, instantly start. and run of the light switch. I replaced, 2 bath fans with panasonic slow start, on its own switch. how much did I save, between the two? a whooping 45 kwh per month, that's $15 a month for me, I paid $126 for each bath fan. for those who have an obsession with payback, I dont, I want comfort. 19 month payback. if electric rates go up like they have been. payback sooner.
Here’s my updated video

Whole house fans are noisy, it will wake up anyone sleeping in the morning. they draw air from outside ,That’s good on cool morning and night but if you live in Sacramento it’s useless in the summer. I use it to remove smells and the occasional burnt French bread lol
we live in south Santa clara valley, today, June 10, 2022 it's 109°, we have no air conditioning, we have. a gable fan, 1050 cfm, not enough, we have a whole house fan, 1650 cfm, now that we have had it for over a year. I'd like it to be larger. more like 2800 cfm. the more times per hour you can exhaust the inside air the better, 1650 cfm, is 10 times per hour, 2800 cfm is around 15 times per hour, you want 15 to 20 times per hour
Not true. I have a quiet cool whole house fan and it’s pretty quiet. Doesn’t sound like a helicopter like old house fans.
You describe a whole house fan which pulls house air into the attic. I did review on a gable fan which only circulates air from the roof to the outside.
Sacramento is the perfect use case for a whole house fan. I live in Sacramento. I'd say 90% of the time it's below 80 degrees by 9 pm. Shut off your AC, open a few windows and turn on the whole house fan. I even have a smart switch on mine that is programmed to come on at sunrise and stay on for an hour. It cools the house in the morning then I close the windows. AC usually doesn't come on until after 2 pm most days. It's great.
