Quietcool AFG SMT PRO-3.0 Smart Attic Fan for Gable Vents - 2940 CFM - Smart App Control - Thermostat and Humidistat - 20ft Power Cord - Plug-and-play - Two Speed

Let me paint a picture for you. It’s the middle of summer, and the heat is unbearable. Our garage feels like an oven, and the attic? A sauna. I was desperate for a solution and stumbled upon the Quietcool AFG SMT PRO-3.0 Smart Attic Fan. Skeptical it would make a difference, I decided to give it a shot. Boy, am I glad I did! Pros: • Effective Cooling: This fan is a game-changer. It makes going into the attic in the summer to grab something actually bearable. And the garage? It’s like night and day—significantly cooler. • Easy App Connection: Connecting the app to my phone was a breeze. Controlling the fan settings has never been so easy. • Quiet Operation: Even on high speed, the fan is barely audible unless you’re right under it and outside. The sound is not overpowering at all. • Improved AC Performance: Since installing the fan, my air conditioner has had no trouble maintaining the set point. In previous years, the AC struggled to keep up during the hot months. • Flexible Installation: The unit comes with cardboard trim to accommodate various vent sizes, making installation easier. • Appearance: The sleek design blends seamlessly with the existing vent, maintaining the aesthetic of the house. • Fit: The unit fit perfectly over the gable vent, thanks to the adjustable cardboard trim. • Power: This fan packs a punch with its impressive 2940 CFM, ensuring maximum ventilation. • Durability: Built to last, this fan feels robust and durable, ready to withstand the test of time. • Value for Money: Considering its performance and features, this fan offers great value for money. Cons: • Installation Requires Two People: Trust me on this—it’s difficult and potentially dangerous to hold and mount by yourself. A second pair of hands is essential. • Additional Supplies Needed: Be prepared with a roll of heavy-duty tape for the seams and around the fan to ensure everything is secure. • Outlet Required: You must have an outlet in your attic to run the fan. • Challenging Summer Installation: Installing this in the summer heat is tough. Plan accordingly. To give you some background, my house was built in 1993. I added blown-in insulation above the garage and in spots above our ranch, which likely helped the overall cooling. Overall, I am beyond satisfied with this purchase. If you’re looking to improve your home’s cooling efficiency, I highly recommend the Quietcool AFG SMT PRO-3.0 Smart Attic Fan. This fan has made a tremendous difference in our home, and I’m sure it will do the same for you!

Great product! We’ve had this unit installed for about a week and it has made a huge difference. Our house has a black roof and the attic can easily reach 130+ degrees on an 85 degree day. We’re well insulated but it doesn’t matter, at those temperatures we cook. On hot days our interior temperatures can reach 95 degrees. With the attic fan the house is running at least 10-15 degrees cooler. Victory! Install was easy and the smart control and Bluetooth app are working well. My only complaints: 1) the specs are thin, specifically about the power draw when the fan is running on high; 2) the fan is loud running on high. We don’t hear it in the house, but I’m glad I chose the gable aimed at the street over the one aimed at my neighbor’s bedroom. I can’t comment on operating cost yet, I’ll report back after a couple of power bills. Regardless, I’m confident that this is a cost-effective alternative to the portable AC unit we purchased last year. Update: We’ve had this unit installed for about a month and it remains brilliant. The operating costs are negligible, frankly we can’t detect any meaningful difference in our electric bill. And it’s effective! We used to suffer in summer, now the house is comfortable. Recommended!

Overall, I’m extremely pleased with the purchase. The Bluetooth makes it easy to control the fan. Allows speeds adjust settings for automatic operation and change any other speeds if needed for summer or winter, temperature and/or humidity level changes, etc. – really easy to use app. I had to build a from for the fan, but either case -- the low speed is very quiet whereas the high speed is a bit louder, but still can’t hear it inside the house—only a hum coming from the ceiling intake. Installation was really easy – about 30 minutes if you already have an outlet near the fan location and (as mentioned) don’t have to build a frame to setup the fan. Since I installed it in the winter, can’t tell if it will saved any money, but I’m sure it will help by keeping the attic cooler.

The unit was fairly easy to install, but I was disappointed in the quality. The metal shroud around the fan and the mounting tabs are thin. The tabs were bent and the shroud was misshapen when it arrived, to the point that the blades wouldn’t spin when I first turned it on. After I bent the shroud back into shape and got the blades spinning, I realized the blades are not well balanced and the whole unit vibrates fairly violently on high, creating a lot of noise. You don’t really hear it on low, but on high it’s audible throughout the upstairs of the house. The fan is a good concept, but I’m disappointed in the quality, considering what I paid for it.

Our attic fan finally gave in, and I had procrastinated on getting it replaced. For months, we actually saw our electric bill be higher than usual by about $20-$40/month due to the increased AC usage. In the three or four months I could have replaced the attic fan, we lost all that money to air conditioning -- a whopping $60-$160 -- that could have easily paid for this fan! Serves me right for procrastinating, but I really, really did not want to go into the hot attic to begin with. Now that weather has cooled down, I finally bought this fan and installed it. INSTALLATION Was very straight-forward. Just follow the included instruction guide. It tells you how to rewire to existing electric wires (if you don't plan on using the included wall plug). WARNING: the wall plug was included so you can test it prior to mounting to the attic. Don't do what I did: I tested the fan on top of our kitchen island, and the moment it turned on, it started moving around. Instinctively, I probably would have tried to grab the fan from falling that could have resulted in my fingers getting chopped off! So, if you want to test the fan, be sure to have it on the FLOOR and put some heavy thing around it to keep it from moving! Don't forget to attach the dampener to the 4 metal pieces that you put the screws through. This helps keep vibration to a minimum. The install guide tells you how the fan should be mounted in order to ensure the best air flow. NOISE At the lowest fan setting, it's very quiet. Set it to the highest, and you can hear it from several rooms away. It's LOUD but also has a really powerful suction. APP App (for Android and Apple iOS) was easily paired to the fan's controller. Once that was done, you could configure it to use WiFi to check for firmware updates. My fan was already up to date when I checked a few weeks ago. With the app, you cannot turn on/off the fan (manufacturer says that this is not needed since consumers hardly ever need to do so -- the fan turns on/off automatically based on humidity and temperature), but you CAN set it to use specific presets where you could control when the fan turns on or off (and at what speed). You could, perhaps, set up a custom preset that would force the fan to turn on or off by setting the temperature limit to something ridiculous. The app connects to the fan via Bluetooth. So, there is a range limitation on where you can control or view the status from.

Essentially, I am giving this product 5 stars. If you only have a single vent and you need to push out as much air as possible, this PRO-3.0 fan is likely the best on the market. However, it is REALLY LOUD!! Anyone who has experience with air handlers or air systems will know that anytime you try to push almost 3000 cubic feet per minute of air volume through a 17" hole, you are going to get noise. This noise is a result of fan motor speed, air velocity as it is pushed through a small space, turbelence from the fan blades and any other obstruction, etc. In my scenario, the fan motor and air noise created a loud mid-range humming/buzzing that just cut right through the ceiling. My bedroom and office are directly under the attic where the fan is mounted and the noise was so intrusive that I could not live with it. This is not the fault of the product because we are essentially fighting physics here. The PRO-3.0 product pushes an incredible amount of air. Outside, the wind noise is not extremely loud but it is loud enough to disturb neighbors in the evening/night. It sounds like the inside of a warehouse factory with machinery running. The way to reduce the noise output in this scenario is to increase the size of the hole for air transfer and also reduce the speed of the fan motor. This will reduce the air velocity since we are using a bigger hole, but it will not necessary reduce the amount of air being pushed out (CFM). This is exactly what I did here. Since I had 2 gable vents for output, I returned the RED FAN and purchased two BLUE FANS which ran at a much slower speed and allowed a larger hole (essentially 2 x 17" which essentially equates to a 24" hole). The noise level was night and day. The noise is SIGNIFICANTLY QUIETER and the system still pushes as much or more air -- and two BLUE FANS actually use less power than a single RED FAN. I did replace the 5uf motor run capacitor in these fans with a Cornell Dublier MPF 5uf oil filled motor run capacitor (part number 32FD3705A-F at $24). This actually resulted in the motor running smoother and just a bit quieter with less capacitor resonance humming. At night in my bed with the two fans running full speed, I can hear a very quiet low frequency tone from the motor noise and air noise. It is much like a comfortable white noise and barely noticeable after I got used to it being there. So essentially, the numbers come down to the following: RED FAN (PRO-3.0) - 2940 CFM (about 1700 CFM real world), 264 watts, 1700 RPM motor speed, 74 decibels at 3 feet 2 X BLUE FANS (PRO-2.0) = 3890 CFM (about 2000 CFM real world), 240 watts, 1000 RPM motor speed, 61 decibels at 3 feet GREEN FAN (ES-3.0) - I did take a brief look at this fan. Yes, the brushless DC motor is much more efficient and versital since it can drive at 3 speeds instead of 2. However, the power supply uses electrolytic capacitors to drive the motor. I would be concerned about long term reliability on a device that operates 15 hours a day for many years in a high heat and high stress environment. Electrolytic capacitors really do not do well in this environment and will dry up and fail sooner than you think. I think the conventional motors on the PRO versions which uses film-based run capacitors will be much more reliable and durable.

Simple install Very affective

Excellent. The long extension cord was great, reached the plug on the opposite side of the attic. Runs much more quietly than I expected. Not every installation 'canvas' will be as perfect as the support videos (mine is an old house with odd gable vents) be prepared to cut the provider vent filler-plates to shape and have some metal duct tape to hand to complete the job. The unit is really good value for money. Will save loads on unnecessary air con / cooling. The app is excellent to configure, good to know what's going on up on the attic!

Upon inspection one of the mounting tabs was bent and broken off and laying in the bottom of the box. The other tabs were bent and scratched as well as the housing and one of the fan blades was bent. This made the fan unusable. I was advised to return the fan which I have done. It looks like a well built product otherwise.
