Tamarack. If you Google "whole house fan" it's one of the main ones that show up. Doesn't move as much as a traditional one you remember from back in the day but it also doesn't require you to cut any joists. So you could technically install 2 of them and avoid having to call a carpenter to adjust the framing and remove part of a joist. But they are pricey kind of. The insulation helps too. Traditional ones will let air in/out from the attic when it's not on and in the summer, but that can be avoided by putting insulation over it in the attic during the winter. This model avoids all the "headache" of installing a traditional one.
@@2010stoofIf you have to hire a carpenter to cut one joist and add 2 shorter pieces , you should stay out of the attic. This thing looks like a bathrooom fan, and overpriced.
I have one in my house and it’s great! I open up the windows at 8:30pm and turn the fan on. I start to notice the temperature starts to drop. Keeps the house nice and cool!
Since my attic was converted into two bedrooms and a bathroom I just got two window exhaust fans and blackout curtains to keep the sun out. If you crack open a window or a door to the bedroom you'll get good air flow. My room use to get HOT in the summer but this new setup works great. And, no cutting of your flow for those that feel uneasy about doing like what was shown in this video.
We had one growing up in our house on Long Island. The hallway vent opened when the fan turned on and it was louvers (they shut by themselves when the fan was off). The fan was in the attic window. I remember how it cooled the whole house off and I felt a light breeze next to the windows. We did not have AC so it was really helpful in the summer months. I have not seen another since, but would love to do it to my house now.
I just bought my first house and it's an older home. Lots to learn! I had no clue what the giant vent thing was in my hallway ceiling but after research it appears to be a non-functioning whole house.

Massachusetts, my family home had one of these (and the accompanying attic) growing up. Now that I’m on the west coast I am pretty sure these things are non-existent lol
Don't know why it's constructed like that, there is 1" gap between the bottom of the joists and the top of the sheetrock supported by those 1" boards. Maybe for wiring or pipes going between rather that holes in joists. The top plate of walls are either 4x or 6x, and what he stepped on look like smooth 1" boards.
Do you have to keep your windows open so that cool air can come in? Also, whats the difference between this fan, and just say running all your vents (bathroom vents - i have 6 in my house, and the kitchen hood vent).
Instead of running your A/C unit 24/7, this fan can keep your house cool when the temperature drops to around 75 degrees. It displaces the hot air in your attic on days when it's cool outside but the sun heats up your roof, and attic temps can climb to around 100 degrees.
sean m yes. Plus the model fan he installed is very efficient. You can run that unit for 12 hours and it probably uses the same amount of electricity as the AC running for 45 min to 1 hour. Venting the attic can help a whole lot too. Traditional insulation doesn't create an air barrier like spray foam does.
> Traditional insulation doesn't create an air barrier like spray foam does. True, but completely foaming an attic is a death trap. It's highly flammable and smokes like absolute crazy. Better to air seal with a bit of foam as necessary, then use rockwool and/or all-borate treated cellulosic insulation for fire retarding.
TilDeath1776 US. Hot air moves to the coldest air mass it can reach. If 85 outside and 70 inside, it will creep into your house by first heating your ceiling. I don't care if it is insulated it will find a way. By pulling house air into the attic you are bringing in fresh air at high volume through residential windows from say a 75 degree day to fill that vacuum. The hot air in the attic can't thermal against the fan speed flow so it will seek primarily the outside 79 degree air at the roof gables. CENTRAL AC is off during this BTW. if you just open the house windows and the gable windows but no fan, then the attic heat would rather escape through your house at 75 degrees than the outside roof air at 79++ degrees. Roof turbines will be the next best improvement to keep the HVAC off more days.
Guess you didn't see the part where he started cutting the hole from the top and that wire laying right in front of him. He just cut from inside the attic where the wire was laying right on top of the drywall.
It is moveable. He cut some, moved the wire to where he had already cut, then kept cutting. You didn't see where it was in the center and he said there was slack and moved it from the center to the outside then stapled it to the blocking?!?
Nice video, which unit model is that fan? According to NEC you can't use insulation foam on wires (Romex) otherwise it will overheat, thus you must derate wire and get proper size. See 3:26 LOL
I am an electrician and this is false. when building block construction homes and sealing off Airways phone is used around electrical boxes and Romex as well as going from first floor second floor to third floor whenever there's Romex going up to the next floor all those holes are also found there has no problems with heat whatsoever
No because the hot air in the attic will not be vented out and continue keeping the attic, and therefore the house, hot. The way they installed it will pull cool air through the the house and also through the entire attic.
They probably could easily enough will all the data they can gather, but dont. I have a nest, and just have to turn off the ac and turn on the whole house fan when conditions are right
I have what's called Quiet Cool in my house, let me tell you its awesome I run it all night in the summer Crack some windows and it circulates air like an air conditioner
@@BIGWOOD3160 dang, that's a lot. My house has a normal whole house fan which has probably been there since the house was built and my house was built in 1951. The thing sounds like a helicopter and has blades that look like a boat propeller but it gets the job done very well. I bet the noise issue could be solved by raising the fan up a bit because the shutters are right below the fan. Sorry if I rambled on too much
Exactly what Kyle said!! Running it in the day time wont help you much unless your home is in a very shaded area with lots of trees to block the sun...Running it at night will significantly reduce the use of your hvac system at night to near zero. If you can deal with the noise which for me becomes white noise after a few mins, they are worth the small investment.
Though don't let you fool yourself by the heat of sun rays. You have to use thermometers to compare the inside to the outside temp. Here in NL it's sometimes 5 degrees (Celsius) outside, but if there is no wind and no clouds blocking the sun, it might feel like 30 degrees Celsius. Extreme example.
Because it all should of been common sense to you... Everyone knows that heat rises, when heat has no where else to go it still steals work from the ac to get it all out.
They really only make sense in dry climates, otherwise you will just pull humid air into your house. Florida is probably the worst place I could think to get one.
Ok so what if I'm in Arizona and in the summer it's freaking still 100 degrees outside in the evenings . How to do I get rid of the hot air in some rooms? Opening the window will only bring in more hot air.
Again, this is designed to VENT out air in the home. Heat rises and will suck the air from the rooms and home and push it out to the attic. But with certain temps, cooling AC will be more efficient
Conqwiztadore22 lol you probably don’t care about the final look. If he damaged it even a little bit, then when he stained it, it would look very very bad
I bought home with whole fan. I had the white Berber carpets cleaned before I moved in. Moved in, turned on the fan and it sucked all the ashes from my fire place & chimney out and dirtied more than my carpets. Had to put a board to in front of my fire 🔥 place every time I turned on the fan. The fan was a quick way to cool down my house. So beware if you install one, it sucks up more than hot air.
you do realize you're supposed to open windows before using a whole house fan in order to prevent things like that..... says so right in the instructions, first thing.
They put a wood strip between the joist and drywall for extra soundproofing but also to help run wires under the joist without having to drill a hole in the joist
My thoughts exactly. They always use super modern, super clean, super new, and super spacy homes in videos like these. That's why when you search "how to install such and such in your house" you should scroll down enough to where you see a normal person doing it, not these uploads by big networks. Even the UA-cam channel "Home RenoVision DIY" is always unrealistic.
It's hilarious how convenient most of these guy's installs are. "You need an attic fan? Okay, lets install one in your 3000 square foot attic with 10 foot ceilings!" "Oh you need a wire run from one side of your house to the other? Okay! Lets use your 2000 square foot basement with air conditioning to run this wire!". I mean come on. You're supposed to be showing people DIY projects. You really think the people doing these projects have homes like that? No crawl spaces. No convenient spaces to move your elbows around in. Take it serious guys.

I think the IRC Code refers to things like dryer exhaust, oven fan exhaust, ect. This just pulls fresh air in through a downstairs windows and pushes it out through attic vents or windows.
Proper soffit and ridge venting. He explained it a bit wrong though. The air won’t leave the soffits AND the ridge vent. The soffits are intake as their below, and the ridge vent is output as it’s above. The chimney effect. With a properly vented attic space that’ll be fine. But would be even nicer to direct vent it outside and not have to worry about the attic space at all! Because it will have more stress on it now (heat & humidity) than it did before.
Works to a point, don't count on humid summers. Close windows on hot side and open on "cool" side and let fan draw air into the house. It only works around path of air, not in rooms without air flow. Not really "whole house" fan, need multiple fans and it only works if outside temperature is lower than inside. Better than nothing. At some point even air conditioner won't help much on extreme hot days plus all the $$$ wasted.
This is not a replacement for A/C. It is a way to cool off the house when the temp outside is cooler than inside, and you don't want to run the a/c just to cool residual heat in the house.
Wouldn't the whole house fan blow all the dust into the attic in the long run? I suppose there's a filter in the bottom but some dust will eventually get through. Also, the airflow will stir up the dust in the attic too, no?
With the displacement of this fan, if you have soffit and ridge vents along with a gable vent, it should be enough exit area for the air being drawn up into the attic. Google search will provide more specifics as to exactly how much venting area you need.
Had similar system that caused mold problems as the large gable vent, the window in this case, didn't allow the ridge to vent correctly. The soffit vents were basically useless in bring in cool air as path of least resistance is the gable vent. Removed the gable vent and the mold issue has been gone a long time now. Just my experience.
@@geomarq123 Hi what climate/location? I'm in SoCal/LA, but don't have soffit vents just gable vent and some ridge vent. Wondering if I need to increase gable vent to allow the CFM to push out safely without blowing "back in" to the home through ceiling leaks. (old home btw)
Could have been finished off as an upstairs bedroom. Even has its own dedicated set of stairs, no trap door or uncomfortable ladder to climb up. Would make a great addition to the home.
Pulls hot air out of the house into the attic. Cool air enters in through open windows. Think of evening when it's cooling down outside but the house is holding heat. Can be a cheaper intermediate step before turning on the AC.
Hi Martha, If there is no window have a screened louver installed on a gable end of the attic, preferably on the eastern end of the house. Would also serve to reduce attic humidity and winter freezing. I'm in central PA. Solidhomes247@aol.com
Open the Windows in the house, turn on the fan. Only use when the outside air is cooler than inside. It cools off the house better than opening windows alone.
here in texas something he did would not fly by code! no electrical wiring may pass thru any opening of any kind that has a mechanical apparatus in use!
Instead of leaving window open for rain and wildlife why not finish the job right by replacing the window with a screened louver? Would also serve to reduce attic humidity and winter freezing.

Get an AC and cycle the hot air from upstairs
Again, this is designed to VENT out air in the home. Heat rises and will suck the air from the rooms and home and push it out to the attic. But with certain temps, cooling AC will be more efficient
0:44 Omg please use a mallet 🙃
Omg so fuck8ng unnecessary?
Conqwiztadore22 lol you probably don’t care about the final look. If he damaged it even a little bit, then when he stained it, it would look very very bad
Conqwiztadore22 also, using a hammer will put more strain on his hand versus using a rubber mallet.
Tommy putting whole body on drywall... Doesn't fall through...epic!
you missed some insulation around the new blocking.
I bought home with whole fan. I had the white Berber carpets cleaned before I moved in. Moved in, turned on the fan and it sucked all the ashes from my fire place & chimney out and dirtied more than my carpets. Had to put a board to in front of my fire 🔥 place every time I turned on the fan. The fan was a quick way to cool down my house. So beware if you install one, it sucks up more than hot air.
If you have a fireplace, you just need to close the damper before running your whole house fan.
you do realize you're supposed to open windows before using a whole house fan in order to prevent things like that..... says so right in the instructions, first thing.
What about installing a solar attic vent fan? Are they worth the price?
Solar attic fan was totally worth it, added one with my new roof, huge difference.
can I use this type can with refrigerated air? or is it strictly for swamp coolers.
You could but why waste energy cooling air of your just gonna throw it outside
Lol you should see the whole house fan in my home! The thing is HUGE
I have a 4x4 one in my hallway.
What do you do if you don't have a window in your attic?
Why was the wire loose between the drywall and joist? 😱
They put a wood strip between the joist and drywall for extra soundproofing but also to help run wires under the joist without having to drill a hole in the joist
Nice 👍👍
Tom makes it look so easy, and it only took him 4.52.
My thoughts exactly. They always use super modern, super clean, super new, and super spacy homes in videos like these. That's why when you search "how to install such and such in your house" you should scroll down enough to where you see a normal person doing it, not these uploads by big networks. Even the UA-cam channel "Home RenoVision DIY" is always unrealistic.
Cool!
What is the brand name of the fan?
What is this fan called?
😂 you have an awesome attic. Why would you put a trip hazard right in the middle of it?
How he drives a 3” nail with only a couple swings. Impressive old timer
Very soft pine and drove with the grain.
My grandpa would tap and seat a 3" nail, then would drive it in fully with 1 blow. Didn't matter how hard the wood was. Master carpenter!!!
Window open all summer long? ?
Where can I buy this exact whole house fan..
I think Northern Tools sells this unit on line. About $600.
I believe it's made by Tamarack... they have 3 different models like this -- link: goo.gl/hVPm5M

I remember watching this episode when I was little
"Difference in your electrical bill"... in a positive or negative way!?! Don't leave us on a cliffhanger.
Zain Haider big increase in your bill lol
Dumb comment. Why would he say it if was an increase to the bill?! People use the whole house fan so they can turn the ac off. Got it now?
@@EDISONTECH LMAO
So, what happens when it rains and the attic window is open?
It's hilarious how convenient most of these guy's installs are. "You need an attic fan? Okay, lets install one in your 3000 square foot attic with 10 foot ceilings!" "Oh you need a wire run from one side of your house to the other? Okay! Lets use your 2000 square foot basement with air conditioning to run this wire!". I mean come on. You're supposed to be showing people DIY projects. You really think the people doing these projects have homes like that? No crawl spaces. No convenient spaces to move your elbows around in. Take it serious guys.
This Old House has never been about DIY. It just shows how something is done. Sometimes it's hard, sometimes it's easy.
Exactly. They always use super modern, super clean, super new, and super spacy homes in videos like these.

Remotes can save a lot of money on wiring.
What kind of fan unit is that?
Nice job. How did he avoid cutting that wire?
I’m sure he saw it in the joist bay from the top and, since it had play, just moved it to cut around it.
How about IRC (International Residential Code) that states you can not exhaust air into the attic?
I think the IRC Code refers to things like dryer exhaust, oven fan exhaust, ect. This just pulls fresh air in through a downstairs windows and pushes it out through attic vents or windows.
What about condensation and other moist-related problems you could get when pushing air from the living area up in the attic?
Tooken care of by opening a window or just opening your attic everynow and then
Proper soffit and ridge venting. He explained it a bit wrong though.
The air won’t leave the soffits AND the ridge vent. The soffits are intake as their below, and the ridge vent is output as it’s above.
The chimney effect. With a properly vented attic space that’ll be fine. But would be even nicer to direct vent it outside and not have to worry about the attic space at all!
Because it will have more stress on it now (heat & humidity) than it did before.
What do you call that stick with the big heavy piece of metal on the end of it I haven’t seen one in years
Is this suppose to cool your house in extremely hot (90's) and humid summer weather without AC?
No.
Works to a point, don't count on humid summers. Close windows on hot side and open on "cool" side and let fan draw air into the house. It only works around path of air, not in rooms without air flow. Not really "whole house" fan, need multiple fans and it only works if outside temperature is lower than inside. Better than nothing. At some point even air conditioner won't help much on extreme hot days plus all the $$$ wasted.
This is not a replacement for A/C. It is a way to cool off the house when the temp outside is cooler than inside, and you don't want to run the a/c just to cool residual heat in the house.
What happens if you lose a remote?
*Attic envy*
Wouldn't the whole house fan blow all the dust into the attic in the long run? I suppose there's a filter in the bottom but some dust will eventually get through. Also, the airflow will stir up the dust in the attic too, no?
Not a problem, just blows it right on out.
People aren't going to remember to close their attic windows when it starts to rain.
What’s an attic window?
Who makes that particular fan and where can you purchase it?
is there another fan that will exhaust the air from the soffits themselves?
With the displacement of this fan, if you have soffit and ridge vents along with a gable vent, it should be enough exit area for the air being drawn up into the attic. Google search will provide more specifics as to exactly how much venting area you need.
Had similar system that caused mold problems as the large gable vent, the window in this case, didn't allow the ridge to vent correctly. The soffit vents were basically useless in bring in cool air as path of least resistance is the gable vent. Removed the gable vent and the mold issue has been gone a long time now. Just my experience.
@@geomarq123 Hi what climate/location? I'm in SoCal/LA, but don't have soffit vents just gable vent and some ridge vent. Wondering if I need to increase gable vent to allow the CFM to push out safely without blowing "back in" to the home through ceiling leaks. (old home btw)
How do I get him to work on my house???
The video and content should be how to add living space to a gigantic attic....
Who has a WINDOW in their attic? LOL!
millions of homes
Could have been finished off as an upstairs bedroom. Even has its own dedicated set of stairs, no trap door or uncomfortable ladder to climb up. Would make a great addition to the home.
Attic gable windows are very common.
We have 3 full size in ours, it's really not uncommon.
tripjet999 I have 2.
where is 6 inches of insulation recommended ?
How many "joists" do y'all think Tom has nailed in his career? I'm guessing far more than are televised.
Where does the air come in from though?
Pulls hot air out of the house into the attic. Cool air enters in through open windows. Think of evening when it's cooling down outside but the house is holding heat. Can be a cheaper intermediate step before turning on the AC.
Nearly hammered the knuckles
Good installation I appreciate it how much does this one cost just curious 😮👍
Why must attic fans suck in air through the windows? Why wouldn't we bring it in through a filter via dedicated intake and blow it out the windows?
What if your attic space does not have a window?
Hi Martha, If there is no window have a screened louver installed on a gable end of the attic, preferably on the eastern end of the house. Would also serve to reduce attic humidity and winter freezing. I'm in central PA. Solidhomes247@aol.com
P.S... I'm on LinkedIn www.linkedin.com/in/ruben-velez-6704aa54/
What's the purpose of this fan?
Open the Windows in the house, turn on the fan. Only use when the outside air is cooler than inside. It cools off the house better than opening windows alone.
here in texas something he did would not fly by code! no electrical wiring may pass thru any opening of any kind that has a mechanical apparatus in use!
Its not. He moved it. Watch the video
Yeah what's the difference in electric bill? It gets higher? How much juice does that thing use?
open windows all summer long? you will have new homies in your house called jellow jackets and some other homies
No screens in your house? LOL
Instead of leaving window open for rain and wildlife why not finish the job right by replacing the window with a screened louver? Would also serve to reduce attic humidity and winter freezing.
brand of the fan
The spray foam can react with the electrical wire insulation Debra.ding it and creating a fire risk.
Tom said your electric bills gonna be higher than I am watching you waste money on a 115 dead center in your attic
Now you will pull all the dirty air with pollen into the house. Go with clean central air.
A lot of studies suggest the outside air is by many metrics cleaner the inside air. Varies by location and time of year no doubt.
That upward facing receptacle is a fire hazard. It can collect dust and debris. Plugs should never face up.
Receptacles can face up, but should have a cover over them when not in use. Like this: www.lowes.com/pd_158461-15527-16445_4294653953__?productId=1038045&Ns=p_product_qty_sales_dollar|1&pl=1¤tURL=%3FNs%3Dp_product_qty_sales_dollar%7C1&facetInfo=
Just use an outlet safety plug. They are $2.24 a dozen at Home Depot. www.homedepot.com/p/Safety-1st-Ultra-Clear-Outlet-Plugs-12-Pack-01711/100199457
Glenn Watkins . Excellent suggestion.
That's been updated at the HD website. It's now an 18-pak for $2.98 + tax at www.homedepot.com/p/Safety-1st-Ultra-Clear-Plug-Protectors-18-Pack-HS230/205885675?keyword=safety+1st+ultra+clear+outlet+plugs
and why would you put a single outlet into a double box??? just put two in with a dual outlet cover plate!!! waste of a double box
Is that a code from the NEC or from the code I’d like to see inspector?
Was hoping to see one that would connect bathroom and kitchen fans for quieter operation, not that...
hmm other type i have seen were mounted to suck air from under house into...
