Hey, this is Adam here with The Solar Truth. I've always been a big advocate of QuietCool
fans. They save a lot of money because you don't have to use your air conditioner as much. It says
on the box here save up to 50 to 90% off AC usage. And that could be true, but it's very optimistic.
Since they're manual that would mean you come home every day when you feel like it's cooler outside,
you crack a window open turn it on, and use it until it cools down. Then you don't need
to use your air conditioner and you're doing that like every day, then maybe 90%. That's still 50%
maybe of your electric bill. So it's going to save you a decent amount and you could do like less
solar for example or you could use more energy on other stuff where you need it, like electric cars
or having your air conditioner on, or turning your temperature down. So basically the way it works is
you're putting a vent in your roof and I'll show that in a second here, and then you crack a window
open on the other side on the other side of the house or downstairs and it sucks that cool air
in from outside cools your whole house and then vents your whole attic. And cools it because the
problem is if you pay attention which you might now and be frustrated about it is even if it's
60 degrees outside and your house is 75 degrees your air conditioner might be turning on all night
because your attic got really hot during the day and is 120 degrees, and is just baking your house
all night. Your air conditioner is then fighting it so that's what QuietCool fans are really doing,
they're helping avoid that problem. I was gonna invent an automatic system with timers, kind of
like pool solar where you have an outdoor sensor, an indoor sensor and I ended up finding one, and I
installed it so that's what I'm going to show you. A fully automatic QuietCool fan that I don't have
to do anything, it works on its own. The most efficiently as possible so it will be that 90%
otherwise you're going to reduce your savings by about 50 to 80 percent with your QuietCool fan
because you're not using it all the time. It's just a pain it's a nuisance. It's not so bad,
I mean manual is fine it works, but automation will save you more money and is just problem-free,
super easy. So I'm going to go and show you how I installed this. My house was
probably one of the most difficult installations imaginable and I'll kind of show you why. First,
this location here like my house in particular my attic space is only above the master bedroom here
and then this little hallway area. Otherwise, it's just all vaulted ceilings,
so this is really the only area that I had to put the intake for the QuietCool fan
so I ended up being able to fit in here which was really the only option. I actually put the temp
sensor right there for the indoor temp sensor which it should go on a wall but the ceiling
it's a very similar temperature, it's not too much different, so it should it work there. And there
was really no other way to do it in this case, my thermostat is right there. Sometimes you can
follow this chase down the wall and because you do have to wire that indoor thermostat
and you could put it next to that or something but that would be the primary location but if
you can't do that then this works. So I have a really small attic and that's pretty much it there
so there's a QuietCool fan the only place that I could really install it was this little space here
that is only a couple of feet two by one foot and this actually isn't a big enough QuietCool
fan for my house so I’m also kind of doing an experiment. What if you have a smaller size can
you just run it more but it's this is literally the only spot in the attic that was possible so
let's jump up here.
The fan itself it's kind of strapped it's a little bit off the
heater but if I do have to work on my thermos here or my furnace then I’ll have to move the QuietCool
fan which it's just strapped on there it's pretty easy to move so yeah I just plugged the quite cool
fan into my outlet there you could hardwire it too it's maybe a little better but it doesn't matter
really in my installation because I have an app to turn it on and off versus having to put a switch.
Basically what I installed was a little unit here with a telephone cable that will connect to my
internet and control it with an app so that's one of the installation parts there and then
that wire comes over here to a little module that actually has an attic temperature sensor
so it senses the temp dramatic and it has two other temperature sensors one is the indoor
temperature sensor which goes right down into my ceiling there. Really no other place to put
that I can't even get anywhere else in this attic it's just ridiculous. So the outdoor temp sensor
was a lot more difficult to install you see the wires there and I actually first drilled this hole
right there. I'll just put it out outside right there and then I went outside and there's no eave
covering it. Because it's not waterproof really it's supposed to be mounted underneath in the
shade so there's no rain or sun hitting it, and there's an eave four feet over right over there.
Rhe eave starts to cover it so I measured it was four feet over and one foot down
so I ended up having to crawl through here with the drill and you can see it's right back there
so nails were cutting my back as fiberglass is cutting everywhere else and I’m sweating profusely
so it was not super fun doing that really hard to reach through there laying down without
falling through my attic as well because there wasn't really anything to stand on or to lay on
so some acro yoga had to be involved there but got that installed and then it's just a wi-fi
connection so you connect it to your home wi-fi with this module as well
and then you have the app so let's show you the operation so my QuietCool fan control here.
My QuietCool is on right now at high speed so I could just have it at low speed if I want. It's in
the morning so it wouldn't naturally be on right now so I had to lower my temperature down to 70.
I have it set for 75 - 76 you want to set it a couple of degrees less than your air conditioning
and I'm fine with 78. But 75 is good so now it just turned off and you just heard it on
low speed. You got your two-speed operation which I guess you could change that but mine
I think default did that and the safety timer will shut it off after eight hours. It shuts
off in the morning when you're not home anyway but you don't need that on if you don't want
to. Then temperature-controlled or timer controlled. You could also do timer control
and then it gives you fewer options and you just have a certain amount of timer and you just have
it on or off, but temperature control is kind of the whole point. What I did here and that's what
I would leave it at. You might have just heard it turn on again when I hit the timer control
so fully automatic it's pretty awesome. This is where my outdoor attic temp sensor is, you can see
up there let's go up here a little bit it's under the eave now
right over there. At first that another hole is right there, but that little white
module there is the outdoor temp sensor. Nice and protected under the eave out of the elements, and
you can see in my attic that was in the very corner. Getting it may be a little more under the
eve would be good but there are not many options there. That was about as far as I could reach.
So one thing that's kind of crazy this is my front door,
when I came home I don't know if you noticed that but if I open my door
it comes to open automatically. Let me show you that again with my hand. There,
it just shoots open so there's a lot of air coming through there right now that's how
powerful the negative pressure is and how much air you're actually sucking into your house.
Now I happen to have a doggie door so I was gonna get a shutter thing that mounted in
the bottom of the window but I was like I bet my doggy door will let that cool air in
and if you can see right now it sucks that flap in and it's moving a lot of air in there. So the
air is just pouring in through that doggy door so that works great I don't have to do anything.
Fully automatic and it just lets the cool air in once the outdoor temperature is cooler than
the inside and then cools the attic down too. All right I just manually turned my fan on so
you can see the air just pouring through the doggy door here quite a bit of airflow coming in there.
My bedroom is on the other side of the hallway and it doesn't really get a lot of airflow so
my QuietCool fan is on automatically pretty much every evening and the nice thing is now when it's
on if my bedroom feels I want some more airflow in there I can just crack a window open a little bit
and the air just pours through inside I mean let's see here
it's just pouring through there and you want to create
a venturi kind of so you don't want to open your window all the way you want to just have a small
opening. That doggy door is perfect because it has a restriction on it or just cracking a window open
a little bit because when you have a smaller space it creates a venturi and it and it creates a lot
more air movement because it's more a jet so you have a lot more air moving just moving all the
air in the house. Because that's what you want to do you want to get all that air in the house
from now in from the outside into the house circulating around and then out into the attic and
venting out the attic to cool the whole house and the whole attic and not have your attic fighting.
My air conditioner never comes on at night anymore it's just a fan using very very low energy.
Thanks for watching this on The Solar Truth let me know and I can help you
get your QuietCool to be automatic as well as any solar or other cost-saving home advice,
battery backup and check us out next time on The Solar Truth. Thanks.
