Whole House fans are mounted in your ceiling and are used to bring the cooler air outside into your home. The second benefit of a Whole House fan is that it cools off your attic, so the entire home can perform better and save you energy. Don't confuse these with attic ventilating fans that mount on the gable fans in your attic and point outwards. Whole House fans actually mount in your ceiling and then point towards the attic. So the difference here is a Whole House fan will complete the cooling process much faster and probably bring your attic to a lower temperature than an attic fan ever could. Fox Family carries two types of Whole House fans. The Quiet Cool brand and the Triangle brand of Whole House fans. We love them both, but for different reasons. People usually find themselves really liking one or the other two. Quiet Cool is a brand that has stormed the industry with innovative thinking and low energy usage fans too. They started out in 2003 out into Mecula California. Triangle Whole House fans are the more traditional style fans. They're a little bit bigger and they might run at a little bit higher decibel rating, but they move a ton of air very quickly and we'll talk more about that later. Getting straight to it though, I want to point out the features of both fans and then let you decide which one is better for you. The first Whole House fan I got from my home was a Quiet Cool Whole House fan. I was drawn to it because as an HVAC technician, I like the idea of attaching a flexible duct to the grill that you see in the hallway and then placing the fan on the other side of that 10 foot duct. That way the sound of the fan is insulated. They have different capacities of fans too. Quiet Cool even has like a sizing formula page on their website that's pretty easy to use. But they are suggesting on their website that we size the system for between two and three CFMs per square foot of your home. So if your home's a thousand square feet, you'll want a system that can move between two and three thousand CFMs of air. So then you go over to the different models and find the Trident Pro 2.5 and the Trident Pro 3.3 will move between 2500 to 3300 CFMs of air. The technology I like about Quiet Cool fans is in the insulated damper that shuts off any access to the attic when the systems turned off. Because the damper has an R5 insulation rating on it, they do a really good job of preventing the heat from the attic from coming into the home when the fan is turned off. In 2011, Quiet Cool became the first Whole House fan to incorporate ECM motors with the fan. ECM motors run quietly and at lower amperages than regular PSC motors. PSC motors are the ones that you've seen on the traditional Whole House fans since the 1960s. They also require a capacitor to run properly and if that capacitor fails, the motor won't work. So you'd have to replace the capacitor before the motor would work. ECM motors are electronically commutating motors. A point I want to make here is that in studying the Quiet Cool ECM motors in the stealth Pro line, I found that they operate a lot better at lower fan speeds. I'm going to touch on that a little bit more. So at my house we have a two-story 2200 square foot home. I installed the 1.5 Trident Pro in my master bedroom ceiling near the door and I put a 3.3 Trident Pro at the top of my stairs on the second floor. I made a video on that one and I'll leave a card at the end of this video so you can watch the install. When I turned those Whole House fans on for the first time, I wasn't really happy with the volume of the air that it was moving. I mean, it was nice, but I guess I was looking for a little bit more. So from then on, I always recommended to people that they get the biggest one that they can afford and use the three-speed switches that they give you and just adjust your airflow accordingly that way. The motors run more efficiently at lower speeds anyways, so okay, well point made about Quiet Cool's volume issues. I've mentioned it a few times before and over sizing your Quiet Cool fan allows you to use lower speed which can save you money in the long run. Triangle Whole House fans. When you mentioned the traditional style Whole House fans, most people think about loud, worrying helicopters, rumbling in their homes and Quiet Cool does a really good job of making that point on their website, but let's take a look at an American classic, the CC series of Triangle Whole House fans. As a technician working in Hot Addix, I noticed how much more these traditional style Whole House fans seem to be moving. In fact, we'll even turn these Whole House fans on during hotter days on install days so we can bring the temperature of the home up into the adding, which is sometimes 30 to 40 degrees difference. And at the same time, the homeowner has fresh ambient temperatures coming into the home through their open windows. On Whole House fans, you're going to find that the blades are a lot larger, they're thicker, and they're more durable, and the built drive is the secret to its Quiet nature as well. The motor sits on top of the frame instead of near the ceiling joys. Other store bought Whole House fans have the motor mounted directly on the fan blade without the use of attention belt. You really have to hear it to believe the difference between store bought Whole House fans and our Triangle Whole House fan. All the noisy traditional style fans I've seen were old too, like like 20 years older, older, so people are always telling me that those things are so loud and obnoxious, but when we install them, man, I really enjoy, I think the sound of them are great. You'll feel and hear the difference in sound and volume of air once it's installed. Think of these as the luxury cruisers of the Whole House fans. So how much air do they really move? Quiet cool fans are sized at 1.5 for 1500 CFMs, 2.5 for 2500 CFMs, 3.3, 4.8, 5.5, 6.0, and 7.0 models. So 7000 CFMs is the max you can get from a quiet cool fan. Triangle fans are sized in 24 inch, 30 inch, or 36 inches around here. They do have a 42 inch and a 48 inch here, but we don't have those around here, we don't install them on the residential homes. The most common 30 inch fan moves over 7000 CFMs of air, and the 36 inch fan moves over 9700 CFMs of air. Well, that's almost 3,000 CFMs more than quiet cool's biggest fan. So that's pretty impressive to me. So where do you install these? Both of these fans, like I said, they're mounted in the ceiling. The Triangle fan is mounted on top of the ceiling joist in the attic, bringing the fan blade further back to reduce the noise. So no cutting of the ceiling joist is involved. The quiet cool fans can be installed in between the ceiling joist without having to cut anything either. And as always, the center of your home is the best place to put your whole house fan. Like my house is zoned, I have a smaller one in my master bedroom and I have a bigger one out in the hallway. Zoning your home with a couple of these fans is pretty common. We like to close our master bedroom door at night, so having a small fan in our room really helps on those nights when the Delta Breezes kicked in. Most people don't create a whole new dedicated electrical circuit for these fans either. We usually tie into the existing HVAC electrical circuit for the furnace, and the reason for that is nobody really runs their whole house fan and their HVAC system at the same time. So here's something you might not know about getting a whole house fan. Getting a whole house fan is a great idea, but do you have enough attic ventilation so that when you draw in air from the outside, where does that air go once it's in the attic? If it just compresses itself in the air and the attic and there's nowhere for that air to go, then you're not really bringing in, you're not really maximizing the potential of the fan. So you got to make sure that you're going to want to take a good look at the ventilation in your attic, because you can only bring in as much air as you can discharge out of your attic. If the air doesn't go out of your attic vents, it will then go down your walls and other penetrations accessible to the attic. Quant cool recommends that you provide one square foot a venting for every 750 CFMs the air can move. So if you've got a 4.8 model that pushes 4800 CFMs of air, if you divide 4800 CFMs by 750, you'll get 6.3 square feet. So 6.3 is the total size of all the vents in your roofing system that's required to meet the factory specs when it comes to ventilating these fans. So DIY or get a contractor. The best DIYers can install these things themselves. A little electrical knowledge about switches and proper ventilation of the attic will go a long way in installing these. Like I said earlier, I'll leave a card at the end of this video so you can see that install. If you do need a little bit more help installing a whole house fan here in the Sacramento area, we'd love to be the company that gets to come out and do that for you. So what are the warranties on these whole house fans? A 15 year warranty comes with the quiet cool systems, and only a one year warranty comes from the manufacturer trying a whole house fans. So that's kind of lopsided there. Quiet cool says that they will replace any part that fails for the warranty of that system. So what do you think? Which whole house fans do you guys think is better? Have you seen or heard these older style whole house fans? And what do you think about them? And what do you think about quiet cool fans? Is it strong enough?
