Fan is quiet enough. If you're on the roof or in the attic, you'll hear its hum but it's nothing overwhelming. Inside the house one can not hear it. It can run on solar power alone. Depending on the sun's intensity, the motor can run at full speed or slower. The included 20V AC backup power ensures that the fan runs even on cloudy days. The built-in thermostat ensures the fan turns on at around 80 degrees F. There is no way to adjust the thermostat nor force the fan on or off. There is a bug / finger protection screen that faces the inside. The openings will keep out larger bugs and rodents but not flies, termites etc. Installation was easier than I expected. Check out the various online videos. I'm an experienced DIYer and have done reroofing repairs. You'll have to determine if it's something that you can handle yourself or have it installed.

Was pretty easy to install, despite QuietCool's video and written instructions being pretty meager. There's a few freelance installation videos on youtube, all with different details. Fan is very, very quiet. I can't hear it in the room beneath it, and actually thought it wasn't running until I climbed on the roof and checked. I noticed the difference in the interior temperature immediately. This house holds heat in the attic and then the entire house heats up and stays hot all night. Additionally, the AC ducting runs through the attic, and when the attic is up over 120 degrees, it takes more to keep that AC air cool in the ducts. I haven't had to run the AC since installing this fan. The house temp is about 9-10 degrees cooler with this fan in service. I do plan to run the included AC adapter to a plug and then to a switch down to the hallway so that I can run the fan when I want. Overall I'm really pleased with this solar powered attic fan. It's gonna lower my electric bill for sure.

I have 2 of the solar attic fans and they work great. They keep my attic 3-5 degrees of the outside temperature. Which if you know attics, they can reach 120-130 degrees. If you duct work attic furnace are located in the attic, your unit is going to work that much harder in the summer months. The only flaw is, which I notice that there are other reviews with the same issue and this is you can get water entering in where the fan exhaust the hot air. What I found out with my situation, it only happens when there is a very heavy wind, hard rain and with a steep pitched roof which I have. You can see the pitch of the roof and the flashing that roofer installed in the picture. The wind blows the rain horizontal, it bounces off the roof into the outlet of the fan. At first I thought it wasn’t installed correctly. Roofer came on 2 different occasions. Checked everything and the attic fan was installed correctly. So finally, one storm that we had with the right conditions I actually went into the attic and witnessed what was happening. So, called back the roofer who installed and explained to him what was happening and he basically said there is nothing he can do about it other then to remove it and put the roof back the way it was. I explained to him if you just put a flashing in front of the attic fan that would block the rain from coming in. Again he refused. With the benefit that these 2 attic fans installed, I was willing to try everything I could not to take them out. I called another roofer and explained to him what was happening and he has heard of this before, which the other roofer said he never seen this happen, and said he would install the flashing. Now we have had 2 storms with heavy wind and rain and no more water coming in. Hopefully this helps anyone else this this issue. Hopefully quiet cool can come up a solution for this issue.

Purchased fan and had it installed by a reputable roofer. The first rain the fan leaked and ruined my sheet rock. Had the roofing company come back out. The fan was installed correctly so they added some more silicone. The fan still leaked. Ended up replacing the fan with another brand and have not had any leaks. I contacted Quite Cool company and explained what happened with the leaking fan. They have continued to give me the run around and have not returned any of my phone calls. Customer service is terrible. They will not stand by their products. The fan was still under warranty, but they did not provide a replacement fan.

My HVAC pros put two in my main house when we put the air handler in the attic. I wanted to cool my garage gym and another room, and added the same model. The installation was relatively easy, as I have a composite shingle roof and new wiring.

I installed 2 of these and the house cools much easier in the heat of the day now than it did when I had 2 whirlybirds
