A financial no-brainer where I live due to high energy costs, reliably cool nights
Size: 3,126 CFM
Style: CL-3100
Climate and Economic Considerations I live in San Diego, California within eyesight of the Pacific Ocean. The night air here is a comfortable temperature even on the hottest days, only rarely staying muggy through the night. Our electric power costs are outrageous: I pay 27 cents per KWh for the first 334 KWh, then the costs jumps to 48 cents. Beyond 1,080 KWh in a given billing cycle, the rate increases to 55 cents. My electric bill for 7/1- 8/8 this year showed 610 KWh of usage with a cost of $233.86, by far the highest I have had to pay since I had 2.5 KW worth of rooftop solar panels installed in 2010. At 2:00 AM the day after I received that bill, it was 84 degrees in most of my house while two small window A/C units were struggling to keep sleeping areas tolerable. Outside, it was about 75 degrees. At that moment I decided to take a serious look at whole-house fans. I did the math, and in under an hour I determined that the QuietCool CL-3100 was the right size for my house and would probably pay for itself in two years or less! My sleep-deprived, heat-addled brain was stunned by this revelation at 3:00 AM. I finally got some sleep, and by 8:00 AM I ordered the system after drinking my daily coffee and reviewing the numbers. This type of system definitely makes sense in coastal Southern California. It might not be as good a fit for a climate that has hot, humid nights and less expensive power. As an example I looked at Houston, TX and was shocked to see that people typically pay between about 7 and 12 cents per KWh. I've spent enough time there to know that the summer night air is often uncomfortably hot. I do not believe that a whole-house fan would be as beneficial there as it is in San Diego, though it might be useful during spring and fall months. Installation This fan system is well-made, easy for a handy person (like me) to install, and moves a lot of air. Rated at 320 watts (on the high speed setting) it uses a fraction of the power of two small window air conditioners I have been using for several years, which are rated at 520 watts each. I haven't done the permanent wiring yet, but the mechanical installation took me just four hours without assistance from cracking open the manual to having a running fan system in my attic. I expect to spend a total of about 3-4 hours installing the proper wiring, including drywall repair and paint. I plan to tap into an existing circuit as the power source. I considered knocking off one-half star for the manufacturer not including some items that are essential for a proper installation of this system, specifically a single-pole, double-throw switch, a countdown timer, a length of armored cable, and a second metal handy box and cable clamps that a typical installation will require. OTOH one size would not fit all situations. Some might prefer to install the fan on a 20-amp circuit, so the switch rating, cable gauge and length, etc. are not predictable. Therefore this fan gets the full five stars. THE DOCUMENTATION THAT COMES WITH THIS FAN IS VERY GOOD. IT IS AVAILABLE ONLINE FOR FREE. READ IT AND WATCH THE MANUFACTURER'S VIDEOS BEFORE YOU BUY AND AGAIN BEFORE YOU BEGIN INSTALLATION!!! My wiring project took longer than expected because I had to get into a difficult area of my attic and drill a hole in a top plate, but it came out fine and I didn't burn down my house or get electrocuted. Factors to consider - Think carefully and do the math! Anyone who is contemplating this type of fan should carefully consider the applicability of a whole-house fan to your specific situation: - Is the night air after a hot day sufficiently cool to make you comfortable if you pull it into your living space? - How much per month are you spending on air conditioning? - How many nights per year would a whole-house fan work as well as or better than your A/C, and what is the expected cost savings of running the fan instead of A/C? - Does your attic have sufficient out-flow ventilation such as gable vents, turrets, etc.? If not, you should take into consideration the cost of upgrading your ventilation. A whole-house fan cannot operate efficiently without adequate attic ventilation. The information for determining this is available on QuietCool's Web site. - How big is your house (square feet of living space?) This is important in deciding which model of fan to buy. - Are you capable of doing the mechanical installation yourself, or with a helpful friend, or will you need to hire someone? The fan with including ducting is rather heavy and unwieldy. Lifting it into the attic was the only part of my installation where an assistant would have been very helpful. (I'm 60 years old and have to admit that this installation would have been a lot easier 20 years ago.) - Are you proficient at electrical wiring? If not, prepare to enlist the services of a kind friend or a professional. (I happen to be very comfortable with it, and have re-wired most of my house.) In summary, buying and installing a QuietCool fan was such an obviously beneficial decision given my locale and the construction of my house. My only regret is not having done it several years ago. It works exactly as advertised, and is much quieter than some less expensive systems I have seen in other peoples' homes. The noise level is quite tolerable for me on the high speed setting. I am looking forward to finishing the wiring, and trying the low speed and automatic shutoff. Read the manual and do your homework before you buy! ***** Technical Note added after completing the wiring ***** The video on wiring a 2-speed fan with an electronic timer has a couple of continuity problems (ha ha.) It does not explicitly say to, nor does it show, including the white wire or the green wire from the timer when connecting the whites (neutrals) and green/bare wires (grounds.) Anyone who has ever wired anything SHOULD know to do that, and if you don't you probably shouldn't take on this wiring project. If you follow the video exactly, you will end up with a stray white wire and a stray green wire. That's bad. The DIAGRAM in the manual is correct. ***** Follow-Up Note added 7/27/2019 ***** I wish to thank Lucky Dog for his thoughtful comment. I agree that it may make sense to have more than one fan, depending on the layout of your home, whether you need to keep interior doors closed, etc. After nearly a year in service, I am still very pleased with the QuietCool fan's performance and quality. I have no regrets at all. (However, I do wish I had purchased about one more KW worth of solar panels when I did that project.) My Tier 1 electric rate has increased from 27 cents/KWh to 28.8, so everything I can do to reduce power consumption pays off. I have had no problems at all with the system. After reviewing some of the negative comments posted in the last year I believe there are two common threads: 1. Some dissatisfied people appear to have purchased fans too small for their homes, and 2. I suspect that some of them don't have enough outflow capacity for their attics. I reiterate my recommendations to fully analyze your situation and carefully read the documentation before making this purchase.

This truly is the BEST Whole House Fan design out there. Easy Install and as QUIET as promised!!
Size: 3,126 CFM
Style: CL-3100
This is the most awesome whole house fan I've ever owned. Very easy to install. I had to add some timbers up in the attic to hang it from due to house design, but that was simple enough. If it weren't for that, it probably wouldn't have taken me 2 hours to install. Full disclosure on that though, my house was built pre framed and wired for a conventional whole house fan so I didn't have to do any electrical work other than wire it up. I would say plan for 4 to 6 hours if you have to pull wiring and make suspension frame mods like I did. It is as quiet as everyone says. This is in the main hallway literally just outside of my bedroom door. I can have this thing on high and not tell it is even on in my bedroom. Standing directly beneath it, you can hear it, but only just. On low, forget about it. You'd have to look up to see the louvres open or stand in front of a window to feel the air being drawn in. And even on low, this thing moves a lot of air!! I loved it this fall, going to sleep and feeling the cool evening/night air washing over me. It still amazes me when I feel how much air is being drawn in through the window, and you don't hear a thing. I've lived in this house for 13 years and never installed a WWF because the noise my past ones made. So loud, and so annoying. Yes, it gets to where you don't even hear it, but if you're watching TV or the radio, you have to turn them up so loud it gets crazy. I started doing some research and found this, thought it was worth the money if it is as quiet as people said because I'd actually use it instead of leave it off. Yes, I could probably buy 2.5 - 3 other fans for what I spent on this one, but sine it is as quiet as it is, I WILL actually use it, so to me it is worth every penny. Why spend even less money on something that you can't stand to even turn on due to the irritating noise?!!

Great investment, but not a quick install, and make sure to have help.
Size: 6,924 CFM
Style: CL-7000
To say that I am impressed with this fan is an understatement. This fan replaced a 30 yr old attic fan that sounded like an Apache helicopter landing in my attic, so my number 1 goal was to install a fan that would actually allow me to run it at night while sleeping without going deaf. This fan met those expectations and then some, on low I can just hear it if I strain, and it is almost directly over the master bedroom. On high it sounds like a box fan is running in the next room, not loud at all. What I was most amazed by, however, is the power this fan has. Our old whole house fan, on high, would pull just enough air thru an open window to feel like a cool breeze, but just barely. After installing this new fan I opened a first floor bathroom window, at the opposite end of our 4000sqft house and I felt like I was in a wind tunnel. It's THAT powerful, that's no joke. The only thing I would point out is that it is not a quick installation, easy, yes, but not fast. Depending on the installation location and fan \ duct placement, expect to spend the better part of a day installing it. And you should definitely get help hoisting it into the attic and holding it in place while attaching the duct to the damper box and the fan itself. It's not overly heavy, but it's just heavy enough to make 1-man operations very difficult. I love the Quietcool fans, I already had 2 attic fans installed in my house, those took about 20 minutes each, this one is equally great but was probably a 5 hour ordeal. Of course your mileage may vary when it comes to installation, but when it comes to operation, this fan is fantastic.
