What Is the Best Whole House Fan System
What Whole Firm Fans Do
Are yous the type of person who likes to open their windows at home? Whole business firm fans are mounted in your ceiling and are used to pull libation air from the outside of the home to the inside. By opening your windows around the house, the whole firm fan will allow air outside to come in. This fashion y'all have fresh air coming into your home, besides as equalizing the temperatures outside and inside.
The second benefit of a whole house fan is that information technology cools off your attic, so the entire home tin can perform better, and save you lot energy. Don't confuse these with cranium ventilating fans that mountain on the gable vent in your attic and bespeak outwards to vent the attic. The departure here is, a whole house fan will consummate this procedure much faster and probably lower the temperature in your cranium more than than an attic fan will.
Fox Family carries two types of whole house fans, the QuietCool brand and Triangle make. We love them both, only for different reasons, and people ordinarily find themselves really liking 1 or the other.
QuietCool is a brand that has stormed the industry with innovative thinking and depression energy usage fans. They started up in 2003 out of Temecula, California. Triangle Whole House Fans are the more traditional mode fans. They are a petty bigger and might run at a petty higher decibel rating, only they move a ton of air very quickly. Nosotros'll talk more virtually that later on.
Getting direct to it, I desire to point out the features of both fans, and then allow you lot decide which 1 is best for your domicile.
QuietCool Fans
The offset whole business firm fan I got for my home was a QuietCool whole house fan. I was fatigued to it because every bit an HVAC technician, I liked the idea of attaching a flexible duct to the grille that yous encounter in the hallway and placing the fan on the other side of the 10 ft duct. This insulates the sound of the fan. QC offers different capacities of fans and a very useful and easy to utilise sizing formula featured on their website.
The formula on the QuietCool website suggests sizing a system for between 2 and 3 cubic feet per minute, or CFMs, per square ft of your home. This means if your home is 1,000 sq ft, you'll desire a system that tin can move between 2,000 and three,000 cfms of air. You lot can so proceed to check out unlike models and discover the Trident Pro 2.5 and Trident Pro iii.3, both of which volition move 2,500 to iii,300 cfms of air.
The technology I like about QC fans is in the insulated damper that shuts off whatever access to the attic when the system is turned off. This also prevents heat from the attic from coming into the dwelling house when the fan is turned off.
In 2011, QuietCool became the get-go to incorporate ECM motors with the fan. These motors run quietly and at lower amperages than regular PSC motors. PSC motors are the ones that you've seen on traditional whole house fans since the 1960's. They require a capacitor to run properly. If the capacitor fails, the motor won't work, and you'll have to supervene upon the capacitor before the motor will work again. ECM motors are electronically commutating motors.
QuietCool ECM Motors
A point I want to make here about speeds. In studying the QuietCool ECM motors in the Stealth Pro line, I found that they operate amend at lower fan speeds. A example in point is with my own two-story, 2200 square ft dwelling house. I installed the ane.v Trident Pro in the master chamber ceiling, about the door.
I put a 3.3 Trident Pro at the top of my stairs on the second floor. (See the link at the end of this post to watch my installation video.) When I turned them on for the start time, I wasn't really happy with the book of air it was moving. It was dainty merely, I estimate I was looking for more.
Since then, I always recommend to people they get the biggest one they can afford and utilize the 3-speed switches provided by the manufacturer and adjust the airflow appropriately. You'll find that the motors run more efficiently at lower speeds. Okay, point made about QuietCool'due south volume issues. I've mentioned it a few times before.
Triangle Whole Business firm Fans
When you mention traditional fashion whole house fans, people think almost loud, whirring helicopters rumbling in their homes. And QuietCool does a good job of making that indicate on their website. Merely permit's look at an American classic, the CC Series of Triangle Whole House Fans.
As a technician working in hot attics, I noticed how much more air these traditional manner whole firm fans seemed to be moving. In fact, nosotros'll turn these whole house fans on during hotter days so we can bring the temperature of the home up into the attic, which is at times 30-twoscore caste warmer! And the homeowner has fresh ambient temperatures coming into the habitation.
The blades are larger, thicker and more durable than QuietCool's. The belt drive is the clandestine to its quiet nature. The motor sits on top of the frame instead of nearly the ceiling joists. This reduces the vibration and dissonance from the fan blade. Y'all really have to hear information technology to believe information technology. (Run into the link at the end of this post to watch my installation video.) All the noisy traditional style fans I've seen were old — maybe fifteen years or older – some even older!
By choosing a new quality-congenital fan, not some big box store whole house fan, you'll feel and hear the deviation in sound and volume of air once it'due south installed. Think of these as luxury cruisers of the whole house fans.
How Much Air Practice They Really Motility?
QuietCool fans are sized in 1.five for 1500 cfms, 2.5, 3.3, 4.8, 5.v, 6.0 and 7.0 models. Then, 7000 cfms is the max you can get from a QuietCool fan. Triangle fans are sized in 24", xxx", 36" effectually hither. They do accept a 42" and 48" but we don't take them around here. The nearly common 36" fan moves over 9700 cfms of air, most 3000 cfms more than QuietCool's biggest fan. That's pretty impressive to me.
Where Are They Installed?
Both of these fans are ceiling mounted. The triangle fan is mounted on elevation of the ceiling joist in the attic, bringing the fan blade further back to reduce dissonance, with no cutting involved. The QuietCool fans tin also be installed betwixt the ceiling joists without having to cut anything.
Nigh people don't create a whole new dedicated circuit for these fans, instead, it's more typical to tie into the existing HVAC circuit for the furnace. This is because nobody runs both the whole house fan and their furnace or air conditioner at the same fourth dimension.
DIY or Contractor?
The best DIYers can install these themselves. A piffling electrical knowledge about switches and proper ventilation of the attic will go a long way installing these. Be certain to check out the carte at the terminate of this video if you'd like to see an install. If you do demand a trivial more help with installing a whole business firm fan hither in the Sacramento area, we'd love to be the company that gets to do that for you.

A Word About Warranties
The QuietCool Systems come with a 15-year warranty. Triangle Whole Firm fans only offering a 1-year manufacturer's warranty. So that's kind of lopsided there. QuietCool says they volition replace any part that fails for the warranty of that system. When I searched the website of Triangle Engineering, I couldn't find the warranty info on the whole house fans, although they confirmed their warranty by phone.
What practice you recollect? Accept you seen or heard these older style fans? What exercise y'all recollect most them? And what practise y'all think about QuietCool'south fan? Is it stiff enough? Let me know what you lot call back in the comments beneath.
