Well, I worked in HVAC years back and have been thinking (more like procrastinating) on this idea that hot air needs to be "pushed" out of the attic with the "in" coming from the soffits, and here I find a great video explaining the whole concept - thank you Vince, the fan model is available on Amazon Canada ! This should be shared with many - the AC's are being pushed way too hard in homes in these heat waves :)
Thanks. The cooler the attic, the easier it is to cool the house, but I’d start with adding whirlybirds. They use no energy. In my area there are times the wind gets still and the whirlybirds don’t move, so power was my solution. Please subscribe so I can get to 100k subs.
Nice video. I will be doing this to my house in Vegas. Previous owner has blocked up attic space above the garage to make storage space. Now there is zero air flow up there. I think these attic fans can be great as long as you are mindful that you need adequate intake air coming through your soffits. Otherwise the negative air pressure will find ways to suck out temperature modified air from inside your house.
Finally did it!! Thanks for the video man! I’m using an static louvre which the opening for the hole is quite smaller, but it’s pushing some air out if it now!! I might get a couple more for the others.
I like the fact that you achieved all this by using old classic tools not the NEW Dewalt or Milwaukee stuff, you eventually need to open up some intake vents under the soffits
Just don't forget to seal your attic of air leaks before installing an attic fan motor. Otherwise the attic fan will SUCK the air out of your house up to and through the attic. Not good because you pay good money to heat and cool your home air.
Instructions indicate that the motor shaft should be horizontal (this is a wall mount unit). Is the motor rated for operation in the vertical direction as mounted? If not it will wear out quickly ...
Good video. You mounted the fan solidly on 3/4" plywood. I would have placed the thermostat further away from the fan, maybe mount it higher at full extension of the BX on a rafter. Also, would have liked a comment on the noise of the fan from inside the house.
The noise isn’t bad. Its a light hum for me, but it’d be different for everyone depending on the level of insulation the location of install and the way it was installed. Thats why I didn’t comment in it. I tried to show it running so people could gauge it themselves. Anyway. Glad I could help.
Nice video I don't have any soffet vents. My house has has the big vents on each end of the gable roof. Its 1000 sq foot two bedroom house. I notice my attic gets extremely hot, would you still recommend one of these vents?

we need to do something about the heat in our attic above garage where items are stored. BUT we don't have any openings at all in the roof, only small vents under the roof (soffits). We did however, air condition our garage w a mini split, and there is a vent in the ceiling of our garage leading to the attic (was there when we moved in). Can we just put this fan above this vent and it will suck some of the garage AC to cool the attic and force hot air OUT OF SOFFITS? - GREAT VIDEO BTW
Keep in mind. I’m not an AC tech, I’m a television editor who works on his own house. But if the vent is big enough and you have adequate intake, then it will move air.
Thanks for the video. Please forgive the ignorance, I am a first time home owner looking to learn and in this case improve my attic insulation/ventilation for my house. So are you implying that a whole house fan is not as necessary as the attic fan then ? Or should you have both, and run them separately depending on the outside temperature ?
I have both and run the separately. Never at the same time. In California the evening temp often drops faster than the AC can drop the inside temp, so the whole house fan can quickly and cheaply drop the temp by pulling in that cool evening air. In the summer, when the temp outside gets over 100° during the day, I use the attic fan to bring the attic temp down so the AC ducts in the attic can move cool air more effectively. This is what I did before I added either fan: The first thing to do is install a battery thermometer in your attic so you can read the attic temp from inside the house. Next make sure you have the correct intake and exhaust vents. Many houses were not built with adequate attic ventilation. Chat with neighbors. If your area allows it. Add whirlybirds. They are the cheapest and best way to vent an attic. For overall comfort. Replace any can lights with insulation rated cans, seal them with led lights to stop air from flowing through them. Then insulate the attic so you have 4” covering the joists. Oh. And Please subscribe so I can get to 100k subs.
Great work Vince! been thinking about tackling this project this summer. Especially after I just cleaned my attic last week, so freakin hot up there! Been looking at some Solar Exhaust fans but not sure if the CFM is as good
I thought about the solar and while their carbon footprint offset is up for debate, I don’t feel they move much more than whirlybirds. And whirlybirds are free to run and long lasting. I highly recommend those first. I’ve been enjoying this attic fan. The house is cooler and more comfortable. But you need to have enough intake vents to handle the cfm output of this. In short this has been a cheep investment with lots of gain, in money and comfort. I’d recommend it.
Thanks Vince! Yes & a lot of Solar ones only work during the day, its nice to have a switch to be able to run it whenever needed (maybe even a timer switch!). Yeah I love whirlybirds, I have a few on the house. But need something for those windless 100+ degree days up here in Northern CA.
It sounds like you’re in the exact position I was in. This runs on a thermostat and I think some of the solars store energy and also run off a thermostat into the night.
Did you save $$ on your electric bill. I have a 1000sf home that uses over 2400 kwh. House is not vented properly and I am going to add 12 to 14 soffit vents to help.
I saved money when I added whirlybirds to the roof. The attic fan hasn’t really reduced my bill as the time it runs doesn’t offset the AC. But in my case I never intended to use it for savings. It cools the attic which cools the AC ducts and that makes the house cooler and more comfortable. I’m sure there is a small savings, but a big improvement in comfort when California has several 100° days in. Row. The fans cost around .11¢ an hour to run. Glad I could help.

@@VinceRocca Thanks. I found a big issue today. I installed 12 soffit vents and during install I noticed a 7 inch pipe blowing 70 degree air into attic. The stove range had been installed with no back draft device. I removed pipe and replacing range hood tomorrow. Thanks.
Is that enough protection from rain, especially when it storms? Is it always on? What about bugs, birds, furry critters, wouldn't they get in and make the attic their home a lot easier?
Ive had mine pointing up for two years. They are working fine. The issue a garage might have is with code and co2 exhaust from cars and the water heater.
the humidty level goes down as the fan helps dry the space of the attic. So overall it helps inhibit mold, mildew and saves the overall roof from heat and winter conditoion
Wiring question. I've got the same fan, 2 black wires off the thermostat. Black to black, white to white, and it just blows my circuit breaker. ?????????????????????
A radiant barrier keeps the attic from ever getting hot and costs nothing to run, but is much harder to install properly. If you can go that route its better than the fan. If not the fan is cheeper and easier to install. Please subscribe so I can get to 100k subs.
Just bought this exact fan. great video! have you noticed a big difference in temps? Are there any benefits/downsides to installing under a roof vent vs. gable?
I haven’t been able to gauge a difference in my electric bill, but the house is noticeably more comfortable. My AC ducts run through the attic, so dropping the attic 10-15 degrees, means the air in the ducts are cooler and the house gets cooler faster, but I’m not sure if the saving in AC is offset by the cost to run the fan. Still I’m happy with it. I imagine they will move the same amount of air under a roof vent or gable. I did install a timer cause in California the fans could stay on all night, and once the sun stops beating on the roof natural convection will take over, so I shut them at 8pm.
For 110v there are 3 wires Black-Hot, white-neutral, green-ground. All metal is grounded to green, all white neutrals go together. And the switch breaks up the black, one black hot into the switch and one black hot out of the switch to the fan. Please subscribe so I can get to 100k subs.
I set the thermostat at 105 and added a timer to shut it at 9pm. In my area, the temp drops to under 90 by 9, and natural convection takes over. No reason for me to pay to force air. There is an improvement in house comfort. I’m not sure how much it will cut my bill. Currently I run 2 fans at .90 a day. My AC costs 1.10 hr to run so if it cuts 1 hour of ac usage, it is awash. But the house is more definitely comfortable.
Its been over a year since this video. Do you have any data about saving money in the long run? I live in Florida and I was thinking of doing this for my In-laws house but I need data to convince them.

You need vents for the attic fan to suck from. Remember air takes the path of least resistance. So if you have a vent next to the attic fan it will just pull from that. In general you shouldn’t cover any vent. Engineers designed your house that way. Sadly many engineers, mostly on older houses didn’t do a proper job. Years ago I had previously measured all my vents and calculated the air intake from the soffits to the out flow of the roof vents. My ventilation wasn’t enough for my square footage. So I added 4 whirlybirds. This fan was added over a particular hot spot in the house and far enough away from other vents that I could assume the path the air would most likely flow. I know this isn’t a simple reply, but air flow is a complex math problem.
Thanks for the response. I guess my concern is that the attic fan will simply pull for the gable vents rather than the soffit vents - which I have a lot of.
Sure. You gotta consider path of least and place that fan far enough away. It’s not perfect for every house. My Dad has a Ranch house with 2 gable vents on each end. 4 in total. A previous owner installed 1 fan over 1 vent on 1 side. All that fan would do is suck air from the second gable vent next to it and not across the attic. They should have installed 2 fans. But, instead, I’m going to remove that fan and install 2 whirlybirds on the roof. I’ve toyed with the idea of reversing the fan to blow in. I wonder if it will blow so much that it will make it across the house. But I think that has too many fire/ dirt dangers, so I’m going with the whirlybirds. One thing to do, is get a thermometer Indoor/Outdoor Thermometer www.amazon.com/dp/B000KKV16C/?tag=povert0f20-20 place the probe at the top of the attic and see how hot you attic gets. If your attic is under 120, then you probably already have plenty of ventilation.
If the fan is in a gable vent on one end of the house, and you have a gable vent on the other end of the house, you're fine. The object is to draw outside air in and blow heat out. The attic heat rises and the air moving from one gable vent to the exhaust gable vent will remove the heat. Soffit vents are not necessary but will increase the venting, allowing the heat to rise to the crest more easily.
I’m not sure what a vent “bar” is, but it is made for vertical wall vents. Glad I could help. You can help me by subscribing so I can get to 100k subscribers.
According to a kill-a-watt 1 fan costs me about .08 hr to run. My Air Conditioner costs about $1.10 hr. But the AC fan without the compressor costs about .15 an hour. I installed 2 fans in the attic and run them 9 hours a day at a cost of about $43 a month. I don’t YET know IF there is a cost savings. I think there. I do know the house cools faster and is more comfortable. It seems I use less AC at 1.10, but I do run the ac fan at .15 hr to circulate the air around the house.
How you enter the attic doesn’t matter. You should have intake vents under your eves. Or gable vents on each side of the house. The fan pulls from those. Not every house is suited for these fans.
1 fan is rated for an 1850 sq ft attic. And moves 1300 cfm of air. The physical size doesn’t matter. You need to make sure you have enough intake to cover the 1300 cfm. Now In my case, I have a 2700 sq ft house with over hang eves, so my attic sq ft is close to 3400. I added a second fan. I have plenty of intake. And they work well enough to make me happy.
I believe so, contemplating the same here... I think you would simply cut a triangular plywood template (instead of his square one), to cover the gable space and ensure proper air flow...
Attic fan is a must have along with proper insulation! Makes a huge difference. I was up in my attic today and noticed my gable was missing a bug screen and did not have that plywood piece. The plywood helps with efficiency. Definitely need to add those two to my existing fan.
I have outlets in my attic for lights and the whole house fan. You can hire an electrician to add one or IF you’re a savvy DIYer you can tap into an existing outlet circuit. Glad I could help. You can help me by subscribing so I can get to 100k subscribers.
It has a thermostat. When the attic reaches a specific temperature it turns on. I have it set to 105. Then when the attic gets cool enough it turns off. I also added a timer to shut it off at 8:pm regardless of the temperature.
Thanks for your concern. I live in California. It doesn’t rain in the summer here. The fans electricity is disconnected in the winter. We have fire retardant blown in cellulose and the fans are on a circuit that is GFI protected. Plus it is equipped with a fire stat that will pop in the event of a fire.
Dude! I love that you attached it to an existing vent. No cutting to roof necessary!!!!
Thanks!!!

According to a kill-a-watt 1 fan costs me about .08 hr to run. My Air Conditioner costs about $1.10 hr. But the AC fan without the compressor costs about .15 an hour.
I installed 2 fans in the attic and run them 9 hours a day at a cost of about $43 a month.
I don’t YET know IF there is a cost savings. I think there.
I do know the house cools faster and is more comfortable.
It seems I use less AC at 1.10, but I do run the ac fan at .15 hr to circulate the air around the house.
What if attic entrance is in garage will it still cool off house or just garage 🤔 ?
How you enter the attic doesn’t matter. You should have intake vents under your eves. Or gable vents on each side of the house. The fan pulls from those. Not every house is suited for these fans.
thats a small fan .did it work
1 fan is rated for an 1850 sq ft attic. And moves 1300 cfm of air. The physical size doesn’t matter. You need to make sure you have enough intake to cover the 1300 cfm.
Now In my case, I have a 2700 sq ft house with over hang eves, so my attic sq ft is close to 3400. I added a second fan. I have plenty of intake. And they work well enough to make me happy.
Sharpie!
Thanks good vid...i subscribe
Thanks.
What are yall thoughts on Attic Foil?
I have no input as I’ve never used it.
Can I put that on the gable vent
Jason Weeks! Warden of the North. Yes you can.
I believe so, contemplating the same here... I think you would simply cut a triangular plywood template (instead of his square one), to cover the gable space and ensure proper air flow...
Attic fan is a must have along with proper insulation! Makes a huge difference.
I was up in my attic today and noticed my gable was missing a bug screen and did not have that plywood piece. The plywood helps with efficiency. Definitely need to add those two to my existing fan.
Looks like yiu have a leak on your roof by the way that ply wood is stained.
where did you get power from?
I have outlets in my attic for lights and the whole house fan. You can hire an electrician to add one or IF you’re a savvy DIYer you can tap into an existing outlet circuit. Glad I could help. You can help me by subscribing so I can get to 100k subscribers.
I see daylight around the edges that's got to be leaking
No leaks.
Good job now cover the vent better so no animals will go into the attic
How dose it turn on
It has a thermostat. When the attic reaches a specific temperature it turns on. I have it set to 105. Then when the attic gets cool enough it turns off. I also added a timer to shut it off at 8:pm regardless of the temperature.
Your roof is leaking your insulation is wet and your fan has started an electrical fire after shorting out!
Thanks for your concern. I live in California. It doesn’t rain in the summer here. The fans electricity is disconnected in the winter. We have fire retardant blown in cellulose and the fans are on a circuit that is GFI protected. Plus it is equipped with a fire stat that will pop in the event of a fire.
can you send fans home to me
Lol
