I had no idea an attic fan of this caliber existed until I researched online to find the best. It costs more than your cheap fans, but it is worth it. This fan is in a different universe altogether from traditional ones. It is so well made, and it is much more hefty and solid than the cheap noisy ones. This fan is quiet, yet powerful, and the 3 stages are definitely a fine feature. On stages 1 and 2, you cannot hear it from an adjacent room or the floor below. On stage #3, you can barely hear it in those areas, but it is so little, and it doesn't interfere with anything. You really have to focus and TRY to hear it. If you were having a special event and wanted the fan to not be heard at all, you could simply turn off the 3rd stage for that period. As for the app, it works flawlessly and seamlessly. This is especially nice because I cannot physically access the fan easily. The Bluetooth connection is good for 100 feet in any direction here at my house. I am rarely this pleased with purchases I make, but I cannot say enough good things about this fan. BUY THIS FAN...!!!!!

I'm very pleased with this fan. It is definitely the expensive model for the category but I already think the value is there. The fan moves a lot of air. While it didn't state the "square footage" on product listing, on the box it says 4000 sq. ft. For me, it's in the attic of a 1930s vintage 1900 sq. ft. house, so it should be able to turn the air over rapidly and without effort - the 3-speed design of this one is especially appealing to me. We live in the deep south on the humid Gulf Coast. The best investment I've made in keeping the house comfortable in the summer was a light-colored metal roof. Even still, the attic isn't a place to be during July or August, so this will keep air moving. Installation was surprisingly simple. It helps that my vents were proper 16" with double 2x4 frames, which matched the fan design perfectly. The little black borders zipped right in, too. The control panel came properly pre-wired with a nice gauge, 20' 3-prong extension cord and I already had an outlet in the attic -- like it was meant to be. The test cycle went perfectly; bluetooth connection was seamless; from underneath the fan in the living room, I could still easily communicate with it. I've set the summer mode and should be ready to roll once the next warm front comes in. With it all said and done, I'm glad to have sprung for this model; hoping I never have to think about it for the next 2 decades....

This is a great attic fan. The Bluetooth feature and app make it easy to configure and control. You can turn it on for a timed period (in hours) at high, medium, or low speeds. In automatic mode it turns on depending on temperature and humidity. And the app tells you what's going on. It's also pretty quiet. We can hear it on high, but not quite on medium, and not at all on low. It moves a good amount of air. Installation was pretty easy, especially if you can reach a plug with the long cord.

The fan in itself is of great quality. Very quite and light built. It is only Bluetooth capable. The app ota easy and the connection is reliable enough. The concept of "cooling" the attic just doesn't work. Don't purchase it if your intentions are to cool down the attic in the summer.

I don’t write effusive reviews but this is one of those must have items for a home owner. You must have attic insulation, a whole house fan and a good gable fan. With that combination house temperatures moderate and your utility bills come down. This is a great fan. Quiet and powerful. It has long lasting bearings. Because it’s powerful I found it runs at a low speed a lot of the time which makes it quieter. And I like that I can connect to it with Bluetooth to see speed, temperature and humidity. It does have a bit of a funky Bluetooth pairing handoff scheme. Check out the manual.

These attic fans are the best. I bought 2 for my house and they are making a big difference. Super quiet on low and medium. You don't even know they are running. On high they make a little noise but you can only hear it if you are in the room below the fan and it is not a deal breaker. I live in Arizona and in the summer it gets HOT. I can check the attic temps on the app on my phone. Attic is staying much cooler. On a 105 degree day the attic is staying around 121 degrees. A man died in Dewey a short while ago after working in an 150 degree attic. These are made in Temecula, CA. It was an easy install. I wish I had them installed years ago.

This fan was exactly what was needed to pull the heat out of our attic space. The air handlers for our heat pump are located in the attic and the temperature in this space reached 150 degrees on sunny days. This fan pulls that heat out by drawing outside ambient temp air through the ridge vent and the vented soffit. Installation was very easy and the extra long cord allowed it to be a plug and play without having to hire an electrician. I love the Bluetooth capable programming with dual summer/winter settings. The manual times feature is a bonus as well. I’m looking forward to our first power bill to see the savings of reducing the stress on those air handlers in the attic space.
