Product Overview

Providing whole house ventilation, the QC CL-5400 advanced fan allows you to bring the cooler outdoor air through your windows, home and attic space by thermal mass cooling. This is what allows your home to stay cooler the next day and resist heating up. QuietCool uses a unique, patented design that features an acoustical duct attached to an R5 damper box. The result is almost zero noise vibration and whisper quiet operation. The QuietCool QC CL-5400 is designed to be installed centrally in midsize homes. Simply open a window when you get home from work, flip on the QuietCool and enjoy a peaceful and cool evening relaxing. And for an even better system, purchase another smaller QuietCool unit for your master bedroom to enjoy a full range of cooling and ventilation.

My 1952 house had an old attic fan that disconnected sometime in the 1990s. I thought it was insane I was running the ac when it was cold outside, so I decided to replace the old fan. My wife was hesitant because she was worried about it being loud. I found this fan and decided to give it a try. The old fan was a 30 inch blade, so I just built a little frame for the quiet cool inside the opening. It was easy since the flapper box is light and I could move it around and drill it in at the same time. I used the provided template make the drywall patch. Some tapping latter, it looks like it was always installed there. One thing I really hated about this was the wiring. Its a 2 speed motor, but it comes wired as a 1 speed on a standard wall plug. Do that many people have outlets in their attic, and what is the point of having a 2 speed motor when it comes from the factory not able to run out of the box? It was easy to replace the wiring to accommodate the 2 speed settings, maybe 5 minutes. If you forget to change the wiring you are going to be miserable up a cramped attic trying to move the fan around and changing a wire when it is 110+ degrees in the summer. I bought a 2 speed switch and now I can run it on high and low. I don't know how to put a value on this. It is considerably more pricey than a traditional attic fan which can be had for $300 or less. The more traditional fans can ventilate larger homes, while you would need to buy a larger quiet cool unit.The previous attic fan was not hooked up so I do not know how much quieter this one is, and that is essentially what you are paying for. Had I had a traditional whole house fan, I probably would not be running it because my wife refuses to "live with a helicopter", with the quiet cool we run it almost every day. It has been a cooler summer than usual some I am not sure about the savings we are getting. I would recommend this product if you are wanting an attic fan but are worried about the sound from other types of models. While it is more than double the price of the other fans, it might be worth it for you over the years if you run it a lot.

    Wow! This product is awesome! Normally, our AC would kick-on around 10:00 am and run until 9:30 pm. With the quiet cool, our AC unit isn’t turning on until around 3:30 pm. We simply turn the unit on around 9:30 pm, and run for about an hour. Again, we turn it on around 7:00 am and run until around 11:00. We have been maintaining between 68-74 degrees (f) in the house. Note: we live in Central CA where summer time temperatures average 98 in the Summer.

    Stay Cool and Save!!
    At first this might seem a bit pricey, but I by the end of summer it will pay for itself. My house A/C takes about 4500 watts while running, and even with solar on my house it still doesn't help enough. This fan saves me over 2000 watts and not only cools the house during the evening, BUT cools down my attic which mean my A/C unit clicks on later during the day. Cool outside air freshens the house and saves me so much money. Easy to install if your a handyman type, and the wireless remote makes everything so much easier. Don't let the cost sway you away!! It's quieter than my A/C unit and I almost forget it's on.

      This is a well-made product. I installed it in my garage, which is about 400 square feet. This fan clears the air in there pretty quickly. I know there are fans that are intended specifically for garages, but I wanted something really quiet. It is indeed very quiet. Surprisingly quiet, in fact. My attic is cramped and has angled trusses everywhere, so the installation was a pain. But the job is not complicated or technical. The instructions that come with the fan are not all that great, but there is a fairly decent video on YouTube, and there is a phone number one can call with any questions. I am glad I got this.

        Fan was great and quite, only hiccup was installing it in a 102 year old house. Ceiling had multiple layers of ceiling so could not install baffle the way it was meant, had to install from room side up, but my handyman did an excellent job modify it.

        This product works great, I only wish we bought it a few years earlier. I installed it a few months back and have been using it ever evening this summer except for one night where it was just as hot outside as it was inside. My Honeywell thermostat sent me an email in the beginning of July that we used out AC 88% less this June than we did last June. It also noted that the weather was 1 degree hotter this year than it was last year. I was skeptical at first for these but several of my neighbors have whole house fans and they all say they love them. You can add us to the list.

          Great whole house fan, drops my indoor temperature by 10 degrees during the night. I recommend you install a 3-way switch to control the high/low speed and a timer switch. Install was not too difficult, took about 2 hours to install the fan and damper by myself, pretty straight forward. Electrical took about an hour. If you have doubts or issues there are plenty of videos and install tips available. I had to install mine at 5:00am to beat the heat, if you can install the fan during the cold season:)

          Works well and lives up to expectations but comes at a premium price. What makes this system so nice is that it is packaged well and allows for easy installation. There really is not much too this fan system….you could easily duplicate the function at less cost by purchasing an attic gable exhaust fan (HD sells many from just $60), attaching corresponding flex duct, purchase a return air grill, and build a damper. But what QuietCool has done so well is small refinements to each component that all work together with a slick clean look. Just to be clear on operation, the outside temperature needs to be lower than the inside temperature for this system to be effective. In our climate the evenings quickly cool off as the sun sets. But the house can remain hot for hours. The fan allows you to pull in the cool evening air and cool the hot house down. When the outside temperature remains high it does nothing to cool the house, as you are just pulling in more hot air. I installed this 1500 in a small bedroom that is just 10x11’ with a vaulted ceiling. I also added a countdown timer switch that is easily accessible from the room. I can close the door and set the timer for 30 minutes just before going to bed and the room is nice and cool. It is fairly quiet, sounds like a forced air furnace running. Each installation will be different but it does require some DIY skills and perseverance. Attics are typically dirty, cramped places and it can be difficult. If this is not your thing think about adding the cost of installation to the ticket. My installation required that the grill be mounted on a vertical wall to reach the adjacent attic. Rather than purchasing QuietCool’s vertical wall accessory I made a plenum box from sheet goods that straddled studs creating a good seal and assuring the gravity damper would close (see photos). I should mention the new damper design provides a bit of insulation for winter months. The only thing I didn’t like about the new damper is its shiny aluminum finish, which can be seen from inside the room through the grill. I didn’t think anything of it until it was installed, but my wife said something immediately. I corrected it with some flat black spray paint (see before paint photo below) but wish I would have done so before installing. Beyond the inflated price this system works well for most of our summer months and I would recommend it. About my rating: 5 stars – Exceeds all expectations. Better than the competition in all aspects, design, cost, operation, and support (A+). 4 stars – Nicely done. Better than the competition and solves the problem. (B) 3 stars – Works as expected. Has some shortcomings but gets the job done. Might be short in design, cost, longevity, or support. (C). 2 stars – Falls short of expectations and needs improvement. Pass and look elsewhere. (D) 1 star – Fails miserably. Does not get the job done, might even make things worse. Someone at the company should be fired. (F)
