- This gable fan has been well worth the money and effort. I’ve tested it on multiple consecutive days of consistent temperatures. It keeps my attic approximately 8-12 degrees cooler in the summer, which in turn keeps the house cooler.
Comment if you have any questions.
The AFG SMT ES 3.0 is the more energy efficient, speed model.

The AFG SMT Pro 3.0 is the same but a less energy efficient model.

It’s just amazing how very close your next door neighbors are, I couldn’t imagine your back yard all your neighbors looking in.
That’s why there are fences
Omg neighbors! For the love of god!
Buying me one man. Thanks
Will do. $500 for shipping 😃
I have an older model of this fan. Mine does not have the smart App connectivity feature. After 7 years of operation, it stopped working. My unit has a 15-year warranty. I'm about to request for a replacement. Overall, I had been very happy with this attic fan. Hopefully, the newer, updated model will have a longer life span.
That’s a huge benefit to their long warranties
What state you live in? How old is this house? The soffits look different unfinished like that. I've never seen the rafters just bare and painted. I'm guessing it monopoly house construction?
Northern California. It’s very common here. No real soffits
My attic has only one gable vent, and the rest are soffit vents under eaves. It’s a metal roof, should I do the same installation as you did? Will it work?
Yes. It will pull air in through the soffit vents
Should you wire mesh on the vent to keep out critters?
The vent on the house should already have the mesh. If it doesn’t, I would recommend it, yes.
so how has it been doing? Have you seen a difference in temperture in the attic ?
Is it pulling hot air out of the attic and is one fan be OK for a small attic?
One fan is usually plenty. At 3000 CFM it will replace the air in the attic every 2-3 minutes. It keeps the attic about 8-12 degrees cooler.
@m10stuff the rats will love the temp. I'm just kidding.
Thanks for this video and tips as far as where to install it about pushing the cool air through the hot air.
I purchased the fan BUT my gable frame is too small. If I add piece of wood on each side I can mount it with no issues.
Is that something you would
Do and recommend if you were in my situation?
@pattayperformance yes. I’ve added framing a few times to have a more secure install and concentrate the air blowing out instead of back into the attic.
@@m10stuff thank you so much for your prompt response! Part of the fan will “blow” right into the original framing. I don’t think it will be an issue.
Thanks also for Light switch/plug combo outlet. I have a light switch…going back to Home Depot to get the combo switch!
Thank you, I have a whole house fan from 1950 I thought I had a manual for it but unable to find.
I went to attic and saw the belt probably original I never changed it I’m here since 1991, went on line tried to find original it’s a Vernco, 28274DF where could I find that? Also where on the motor is the oil port. I believe back 30 yrs ago I use to oil it but my memory is shot.
The motor is from St Louie Mo, USA.
Model number K55RXRL-8033.
Serial Num 30052. Any suggestions
Ty
A proper belt at the proper tension is very important. Im not seeing anything online for that. A small motor shop may be able to help. As far as energy efficiency and CFM, it may be time for a complete upgrade.

Im also from California (central California 90+ days every summer). How has this helped lower your home temperature/electrical bills?
I can’t speak directly to my electrical bills because I have solar. But I have tested it on consecutive 100 degree days. It does keep the attic about 7 degrees cooler. That might not seem like a lot, but that’s less heat radiating into the house from above.
i live in california and where i live the humidity is pretty bad here gets about 58-68 percent humidty.
Will this fan be OK to get rid of dampness and heat from the attic? Im currently having mold issues in the ceiling
It has humidity settings as well. It can definitely help with humidity. If it’s too humid (90%+), it can turn itself off so that it doesn’t bring in too much moisture.
thank you i will go ahead and order one of these.
thank you for the great video @@m10stuff
I'm curious. One gable is on the northern side of my house which gets shade from a persimmon tree from about 1pm - 2pm onward. The southern gable is just above a metal carport roof. My gables are triangular, and I really don't want to box one gable in to get a "perfect" seal so to speak. I was wondering if mounting one of these fans in the middle of the attic, pulling cool air in from the northern side, pushing the hot air out the southern side would work? Granted it wouldn't be the most efficient in doing so, but my thoughts are with a high enough CFM, in theory, it should work. My house is just 1,000sq ft. and the roof is relatively low pitch, so the attic isn't that large.
When it's cool enough in the evening, I use a 20" high velocity fan (5,000CFM I think) in one window, and open the others, works like a charm. I just need something to push out the attic heat when I can't open my windows. Thoughts?
It may help a bit, but because the air would take the path of least resistance I think it would just circulate the air that’s already in the attic much more than bring in fresh air and push out hot air. It really needs to be mounted in a way to force air in our pull air out.
@@m10stuff I appreciate your reply, I'll take your advice in to consideration.
Not going to work properly the way you have set up. Vent is much larger then fan. When fan runs as you have set it up it will not pull air from other vents but will pull air from vent you have it mounted the exhaust fan . Short circuit in another words.
Must mount fan on plywood that completely covers vent not allowing air to be sucked in from that vent it was mounted on . Must cut hole on plywood size of fan and seal it to plywood with tape avoid any bypass.
I couldn’t believe that you mounted as you did
You never mentioned any of this only talking about mounting it. You do mention using shields that’s what they are for but need to cover entire vent to seal it around the vent.
I’m understanding that you think I should completely block the gable vent next to the fan? My concern with that is blocking natural ventilation when the fan is not running. Also if there’s a whole house fan installed, it needs more ventilation. I can’t block 2-3sf of ventilation.
@@m10stuff caveman English ? Ok caveman electrican what’s your next job in California doing illegal installations of fans. All your wonderful bs is wrong you and set an forget it talk is not going to help do anything to made it effectively do anything to cool the attic . So mr caveman go stick you head in the ground and do something else besides waiting people’s money with your half assed installations you claim to cool an attic.
I see you are getting a terrific response to to your caveman electrical electrical installations good job ! Your wonderful
Yeah you didn't think this one through, I agree with the OP.
1. the fan will pull air in the attic from right around the fan because of the opening. You even talked about why they provide the flashing with the fan, and then ignored that. Lol
2. Idk what geographic region your in, but most of the US has warm air moving from south to north. Putting the exhaust on the S facing side is just fighting the natural movement of air.
Ever heard of "pissing in the wind" that is exactly what this is doing.
adding a outlet doesn't make it a dedicated circuit by any means...you would need to go straight to the panel
@@TK-ri5eg a dedicated circuit is not needed for these. I was referring to the furnace
I’m not crazy about it having an app to operate it. Apps always fail after a few years.
Most attic fans don’t have any controls at all. They work strictly off of temperature settings. This is no different. The app just lets you change those setting without climbing into the attic and changing them manually.
@@m10stuff gotcha.
I read a report that these fans increase you electricity bills. Fans draw cold air from the home due to leaks causing the AC to start. A home attic must be sealed for air gaps before you attempt to play engineer.
Air is going to be pulled from the path of least resistance. There is lots of existing net free ventilation in the attic that would be used long before a tiny hole in a wall buried in insulation.
@@m10stuffthat is a fair argument. I do have concerns though for my situation. I have lots of led can type lights.
Rats.? Not mice..Rats in your attic..Much bigger problem .$$$ To fix that first..😢😢
That’s super cheap and easy to fix. They were already dead
