Answer: 
The sound is similar to a ceiling fan on high, and that is right next to the fan. At 12' away on my roof I cannot hear it. Inside my house I cannot hear it at all.

Answer: 
The noisy fan is in the attic above my bed... so I am acutely aware of the noise inspite of the fact that I use a breathing device. The noise is heavier than a vacuum cleaner and is a drumming stemming from an out-of-balance fan blade. There is no noise I can compare it to, but it is a heavy drumming noise.

Answer: 
Thank you for contacting Master Flow ... Our fans are very quiet. I would compare it to a refrigerator fan motor in operation.

CUSTOMER REVIEWS

Rated 4.5 out of 5 by 42 reviewers.
Rated 5.0 out of 5.0 by Great power vent. I had the vent installed by a professional. It works great, is quiet and helps keep the garage cooler. May 17, 2016
Rated 5.0 out of 5.0 by Cool running :) I hadn't installed a roof mount in 40 years so I was nervous but all went GREAT. The heat that came out once I punched the hole was like putting your head in a hot oven. Instructions were simple, it's all about organizing your work. I have very sensitive hearing and it took a very quiet room and concentration to hear the fan from inside the house. We love it and notice the considerable difference in our home temperature. PS I watched a couple YouTube videos to help with confidence on installation. August 4, 2015
Rated 5.0 out of 5.0 by This Fan Rocks! This was a piece of cake to install. I removed an old heat vent from the roof and cut the existing hole with a jigsaw about 1.5 inches larger. I slid the unit under the shingles, nailed it down and used plastic roof cement as instructed. The electrical hook up was easy as I tied into an existing circuit found in the attic and tied into it using 20 amp wire, staples and a new j-box with switch. This fan has cut my run time on my 5T unit by 25%. I set the t-stat @ 80deg for now as I want the attic to cool at least this low. I'll re-adjust to 95 in July sometime. Great product, low electrical usage and BIG savings on my HVAC usage. June 10, 2014
Rated 4.0 out of 5.0 by Power attic fan It's good price recommend to buy. Run quite n easy to install. January 21, 2016
Rated 4.0 out of 5.0 by A good value roof mounted power vent Like all of us, after reading reviews I decided to install this unit in our attic. We're located in Kansas, and our summers aren't like the south, but we do have hot and humid days. The local HD had 3 of these units in stock. Upon opening, the unit was in good shape, no damage. It appears to be a well made fan assembly. I did notice that the "varmint" screen was pulled taught and there was about a 1/4 " gap in some spots. That was quickly remedied with some silicone. The instructions were 1 page with 7 steps. Enough info to do the job for most DIY folks. The container had a 15" diameter template for aiding in cutting your access hole. It took me about 3 hours total to install. I had some sealing membrane leftover from a skylight install, so I used it to seal up the flashing under the surrounding shingles. The color of the cap matches our shingles perfectly. I would have been ok with plain steel or black, but "Weatherwood" is a great color. In addition to the sealing membrane, I also used pure clear silicone to seal everything. You can opt for roofing tar, but if you're not careful it can get away from you and end up in places you didn't want. The thermostat hasn't changed much over the years. Easy hook up to your incoming power. You will probably need to purchase a wire clamp for the thermostat box to be in compliance. That will prevent the wiring from rubbing on the sides of the bare hole. The fan runs fairly quiet. And it does pull more than enough air out of our attic. It comes with a 5 year limited warranty on parts, and an additional 3 year "labor" warranty to have someone remove the fan and reinstall it. Not bad. All in all, I believe this fan is a good value for the current purchase price ($85.50). November 9, 2014
Rated 5.0 out of 5.0 by Definitely works! After installing this fan, our home stayed cooler, the AC kicks on less often and runs shorter when it does. Installation was pretty straightforward and it's still running strong almost 2 years later. Thinking about installing another one or two soon. October 14, 2015
Rated 5.0 out of 5.0 by I believe this fan is saving me money and I know my ac is running a lot less. I debated back and forth about this fan. Some say a powered vent fan will cost money not save it. My ac was struggling and my attic was very hot, 141 degrees. Now it is 105 with the thermostat set on 100. After installing this vent fan my ac has been cycling more and I have calculated the cost to run the vent 10 hours per day to be just under $6 per month. My ac has been running 1/4 to 1/3 less during the day so I am almost positive I am saving money on electricity and it is less wear and tear on my ac system. I have a low pitch roof 3/12 and I cannot hear this fan run with everything else off standing directly under it in the house. I bought this fan from the orange box because it had, what looks to be, a better motor than what the blue box models offered. I installed it my self in less than two hours. The hardest part was removing the nails from the shingles so the unit could slide under them. August 3, 2015
Rated 3.0 out of 5.0 by Decent value I purchased two of these roof ventilators, having had two on my house for many years (26). After installing the two most recent attic ventilators, I found that one vibrated and made noise excessively and it must be replaced. I love the usefulness of this product and believe strongly in the energy efficiency it adds. It seems like the replacement ventilators are superior in quality to the two that they replace and that is pleasing. But I dislike having to get up on the roof to replace one fan blade or one motor and fan blade to solve the vibration/noise issue. I believe that better quality fan balancing and better packaging design would go a long way toward delivering a very high quality/high value product. I should add that the county I live in does not accept these electric ventilators as adequate long term attic ventilation because of the lack of reliability of these units. But I believe so strongly in good attic ventilation that I put them on anyway and added 7 passive roof vents in addition to get my inspection passed. Both my money and my mouth are together!
