My new home came with one pre-installed and I absolutely love it.

We had one in our last residence. It was awesome. We'd wait til Bout 9pm, open all the windows, and in 20 minutes the entire house was crisp and cool. Saved us a bunch on AC costs.

If you were in Hellifornia where a 1,000sq ft well insulated apartment gets $400 electricity bills keeping the thermostat at 81, you'd realize a large house electrical savings your first bill, so much so you'd throw a party with the $600 you saved off of a normal $800-$1,200 bill which is typical house bill for CA in the summer. I installed whole house fans in 3 houses in CA because the PG&E bills were so horrific. They've become much more horrific since PG&E was directly responsible for burning down 10+ towns and CA allowing them to constantly raise their rates. You can literally buy a Quiet Cool with the savings off one bill... Quiet Cool wasn't around for my first 2 homes. I had the biggest fan I could find and stuck it in the ceiling. It sounded like a jet plane but I absolutely did not care as all of that amazing cool night air came in and I knew it was blowing the 130+ degree heat out of my attic.

I would love to have one of these. I live in N Texas and this would come in handy at least 6 months out of the year.

I paid $2,100 for a QCSTLPRO 4.8 wireless remote installation, well worth the cost.

What about using filtered fresh air returns with some check flaps? Would it be able to pull enough to draw through the fresh air foundation vents?

My question is does it drawn in a lot of dust into the house have you noticed if you need to clean more often?

I own one of these and absolutely love it. I've had it for probably 10 years now. My question is the following. Looking to install this for someone else, They have a two-story house and the attic is such that I can possibly put this fan on the first floor. Do you see any issues with installing the fan on the first floor? Seems to me it shouldn't really matter. As long as at least one window's open it will pull air from wherever that open window is. Thank you!

Don't buy the Energy Saver 2 speed version (Green) sold to home owners featured in this video. Sold without controls and with only 10 year warranty. You want the Stealth Pro x 3 speed model (Black) with 15 year warranty.. These models are sold to contractors only. Most contractors can install these models with RF Remote for around the same price you will pay retail on an ES model. Also, you can buy an extra remote without buying 2 complete remotes. This will enable you control the fan from bed or upstairs and down.

I have a question. I read that it's recommended to pair an attic fan with the quiet cool fan. My understanding is, an attic fan will kick on automatically when the attic gets super hot, and this is a good compliment to the quiet cool fan. Any feedback would be welcomed.

Have a quick question hopefully you could answer so if I have my windows closed, and my house is warm or hot and I turn on the quiet fan. It won’t suck up the air. The windows have to be that kind of doesn’t make sense. I understand the part of having the windows open, but I think that even if your windows are closed, it would still suck up air Into the attic

My current house has a similar unit, but it's very noisy because the fans are right at the grill. This setup is better. ONE CAUTION: Make sure you have enough outlet for the air, otherwise you will pressurize your attic which may push hot & dusty attic air down into your living space.

So what kind of exhaust vents do you need in the attic?

One factor to consider with this approach is how well an attic and vent it's own air. If not that well, then pushing house air into it with the WHF will tend to make the attic behave like a balloon - not as efficient at evacuating house into it, because there's no where for it to go once it gets to the attic. If the attic has good ventilation, then a discharge into it would achieve one of the intended secondary goals, of lowering the attic temperature. If it doesn't, then I'd think you could add an attic fan. Or as a previous comment suggested, have the WHF discharge directly out a gable vent. It seems like it would would be relatively simple for the controller to have an option for temperature-based control: have a temperature sensor outside the house, one inside, and the a controller where you could set the delta (ie. outside needs to be > 10 degrees cooler), that would automatically turn on the fan. You'd want this as an option, as if that was met, but you didn't open your windows, you'd be evacuating that air into the attic, with no replacement.

What about the reliability, quality, and longevity of the actual unit? Any customer service issues with the manufacturer?

Do you have to cover up insulation before you turn on the fan?

Does it not turn off when you press and hold it?

This doesn't create humidity issues in your home?

TX here... there's no such thing as cool air during 6 or 7 months here.

These don't make sense to me when used this way if you a drawing air from inside the house some of that air will have moisture so any vapor barrier would be useless. For me you would need two systems the whole house fan should vent straight out of the gable end thus keeping the any integrity of any vapor barrier and exhausting warm moist air straight out. The second system should be purely to cool the loft space as heat can build up here very quickly and radiate down into the living space. The second system has more benefit IMO as no matter how how it is outside the loft space will be hotter unless it is well thermally insulated.

lol, obviously not designed with Texas in mind... :P

110 deg outside is not cool.

Video is way too bright. Wtf
