Quietcool QC ES-3100 RF Energy Saver Advanced Whole House Fan with Wireless Control - Up to 3081 CFM - As low as 81 watts - Two Speed - Covers up to 1,541 SQFT - 10 Year Warranty

Been toying with installing one of these systems for years. Live near the coast in Southern California and have AC. But we really only have issues with heat later in the day after the sun goes down. The temperature at that time is actually cool outside, but it takes forever for the inside temp to drop. Costs to install were $2500-3000. Figured I'd do it on my own. Grabbed this unit off Amazon to install in our 1450 sq ft home. Instructions are pretty straightforward, but I still had to figure out where to install it in our tight attic space. A couple of trips up and down the access and I got it. Made pilot holes from the attic, traced the cutout with the included stencil, and cut the access hole. Installed the vent in the ceiling, but had to figure out how to get the rest of the unit up into the attic. Didn't want to remove the ducting from the fan because it was a pain to re-install (especially up in a tight attic). Had the wife hand me the fan through the access and pulled it up. From there it was relatively easy. Attached the other end of the ducting to the vent, installed the hanging screws into a rafter, and hung the fan head. We have an outlet available in the attic, so there was no need to run power. Paired the remote, tested it, all done. Advice for self-install....Take your time. Start your project early in the day. I started at 730 a.m. on an overcast morning. Took about four hours start to finish. But I probably still sweated out a couple of lbs of water. System works great. You do have to be strategic about what windows to open to get the flow you want. It's not quiet. You can definitely hear it on high speed. Low is barely audible and seems to do the job anyways. Overall very happy. Price was a bit steep. I mean it's a simple fan, with ducting and a shutter vent. The remote is basic and there's no option to control it via Alexa or other home automation. $1300 seems a bit steep for something this simple. But it's done and now I can just enjoy it.

House: 700sqft, 2br, 1 ba, 1 floor cap style. Location: Southeastern Connecticut. Installation was simple, however cutting the hole in the ceiling was challenging due to my sheetrock is not what you find in modern houses. My house was built in the mid 1950's and used plaster. This is by not means any fault or issue with the fan housing at all. Just noting this for anyone in an older home, be ready to do some patching. Purchased the house fan back in early March. Installed a couple of weeks later. Only used it 3-4 times so far. Before I purchased I asked "what model would I need for my 700sqft house" and the seller responded with the QuietCool QC ES-3100 model. My attic already has one of attic fans, the QuiteCool solar attic fan, and its been a solid product for years. This thing is a monster, yeah its beefy! Everything is boxed up well, no damage at all. Thanks to Amazon delivery, it arrived unharmed. They delivered it in a box truck, not their normal delivery van. I unboxed it in the living room, and found a central location in the hallway near the attic steps. My house is very small, I did consider installing it in the kitchen to help with cooking smells and heat from using the oven. Placement was key, and I traced out the box location, and as mentioned earlier, I didn't have sheetrock, I had to use a sheetrock tool, and a jigsaw. The jigsaw wood blades wore out before completing one of the 4 side cuts. When I said its not like sheetrock I am not kidding. I have to pre-drill a hole to put a nail in the wall. The best method is to mark your corners, and drill a hole large enough for your jigsaw blade to fit. Then from living space area, mark a line outlining your 4 drilled holes where to cut. Your cuts don't have to look perfect, the faceplace will hide your cuts well. I removed 1 long side bracket, and used an oscillating tool to cut the nails that were in the way of the other long side that goes between the joist and the sheetrock. This will all make sense when you start the process. I then used 2 construction grade screws in the roof joists to mount the fan and connected up the insulated air tube. My attic did not have an outlet, but it did have a light fixture, so I had to install an outlet. Easy for most, but some might need an electrician to do the install. This unit comes with a wall mountable wireless remote, I did mount mine in the hall, hidden around the corner. You need to pair the remote with the control box, I suggest you do that immediately after you get it mounted and connected to power. The remote is wonky, it takes a couple of touches to wake it up, then you need to press your options once you see all options light up. The remote shows a H M L fan speed option (high medium low). This model only functions on High and Low. I took 1 star away from it not coming with a Medium setting (I'll elaborate later). Low fan setting works very well with 3-4 windows opened about 4-5". It will blow the curtain and you'll feel a nice steady breeze near the window. Noise is minimal, its no louder than the dryer in the basement running. It will not overpower or drown out your TV or conversations. At times you might not even notice its running. High fan setting will certainly get the air moving! if you keep the same 3-4 windows open, it will blow off anything on the window sill that isn't heavy. I suggest opening those 3-4 windows 6-9" to allow for the additional air flow. Noise is now at a level where you can hear it, its a low drone sound and will not drown out a conversation, but you'll need to bump up the TV volume a little. Keep in mind, I have a very small house, and its all 1 floor. those with 2 floors and will barely hear it I am assuming. Overall use of this has been a pleasant experience, I am glad I got this, however after some use, I really really wish it has a medium setting. There is an extreme difference between low and high that it really warrants a medium. Does it move air, yes.... yes it does!! Would I get this again, YES. Do I recommend this? YES. Can anyone install this, yes, and no! Yes to those who are handy, and can do basic electrical wiring. No to those who are not handy and unsure how to do wiring. I would equate this to a skill level for anyone who could install a ceiling fan where there is no junction box already. If that is a challenge to you, you might want some help. The fan is heavy, and you might need a helper to hold it while you mount it using the metal straps. Sorry I didn't take pictures of the process or the final install (I might take some the next time I am in the attic) Be sure to get the appropriate model for your square footage, I would verify it with seller.

This unit has been great. Easy setup , helps with the power usage in spring and the fall. Not too loud really. You can hear it but not overly loud. I would recommend.

I love my fan, it was easy to install and now I don’t wake up in a cold sweat during summer nights. I only have to open a few windows in the house and the air will blow through like crazy! Very happy with my purchase :).

I love my new house fan!

The fan itself is excellent. It’s quiet, powerful, and efficient. However, a few aspects of the installation haven’t been well thought out. Most importantly, the motor controller is mounted on the top of the fan. If you have a shallow attic, the controller ends up right below the roof, which means you need to remove the fan from the hanger straps to see the controller LEDs, press the test button, or pair the remote. You can’t flip the fan around to put the control on the side or bottom because the straps are too short. Second, you are supposed to drill the provided screws through the drywall and then through sheet metal flanges, which aren't supported in the back. That might be fine if the screws were self-drilling, but they aren’t, and they can’t penetrate the flange on their own. You end up needing to pre-drill holes or get self-drilling screws. This is a fairly minor hassle, but it would’ve been so easy for the manufacturer to include appropriate screws, especially for a fan that costs more than $1,000. Third, and this is just the manufacturer not explaining installation well, the instructions are for joists 16" or 20" apart. Mine are 14-1/4" apart, but the damper box fits when both side flanges are removed. Finally, the power line hookup and duct fasteners are now much better than shown in the instructions, which is great, but why aren't the instructions updated (if you have to get them online anyway)?

The installation was easy! I wish it had WiFi! I would have given it 5 stars! ( basically sounds like a fan!)

Absolute game changer in our house. We don't get a lot of air by just opening windows or even using box fans, so we often replied on A/C even when it was cool enough outside to not need it. Now we just open a window on the other side of the house from the Quietcool inlet and let it draw air all throughout the house. Add in that the airflow crosses the main cold air return for our HVAC, so we can now turn on the main HVAC on fan only mode to move even more cool air around. This uses so much less electricity than having to rely on the A/C. Noise levels are just OK. I wouldn't call this totally silent. On low, there is a constant low rumble - like someone has a car running outside - almost imperceptible if watching TV.or something, but audible if it's otherwise quiet. On high it's comparable to a box fan in another room on high - you will always hear it, thought it is not super obtrusive. The RF wireless functionality is great, but the wall mounted remote looks out of place compared to regular wall mounted switches with switch plate. It just sticks out like a sore thumb because of how thick it is. We ultimately removed it from the wall and just leave it laying around like any other remote. That being said, the place where this is really lacking is that it is not "smart" in any sense of the word. It's 2025. Something with a remote should also be able to be controlled by a proprietary app at minimum, or better still compatible with modern smart home systems like Smartthings, Alexa, or Google Home. If they updated it to work with smart home systems this would be a 5 star device hands down. I do wish I went a size up over their recommendations since I'd like to see just a bit more air move on low to keep the noise down instead of using the high setting, so bear that in mind if you are looking for less noise. Low gets the job done, just slower. So if we need a quick cool down we will use high speed just to cool things off quickly, then switch to low once things are comfortable.
