Answer: 
Yes they advertise as quiet but this louder than my previous whole house fan! It is not 65 db as stated. My db meter says 85 db on low or high. Because low is only one fan spinning on high speed. Which is not efficient as it just pulls air from the attic when the other fan is off.

Answer: 
The decibels for this fan are 65. Our 30" WHF is 72 on high speed. The pitch of the Tandem is higher which can make the fan seem louder if you are more sensitive to higher frequencies. The 30" WHF has a lower pitch sound so it appears to be more quiet. The noise level will be perceived differently by different individuals. Please call Technical Services at 800-211-9612, M-F 8A-5P ET, for additional Read More

Looking it over, I see no reason that it could not be mounted on a side wall, but I would defer to the manufacturer's recommendation. The electric door works against gravity when opening, and with gravity when closing, I don't see how it would be affected be side mounting with the same stress on the electric motor, but I can't see inside the unit to be assured.

The remote is RF, so it works through walls, and seems to work fine most anywhere in my house. It has an on and off button, a high and low button (actually turning on one or two of the fans) and a four hour timer that when pushed while the unit is on, will turn it off automatically in four hours. It seems to work just fine. Read Less

Answer: 
No, the power has to be routed through the IC card inside the fan. It coordinates the automatic opening and closing of the insulated lid. Please call MasterFlow Technical Services at 800-211-9612, M-F 8A-5P EDT, for any additional questions.

Rated 2.8 out of 5 by 33 reviewers.
Rated 5.0 out of 5.0 by Great Fan I love how this fan opens and closes when you run it on and off. No worries about sealing it in the winter. To me its no noisier than any other whole house fan. We installed it in the hall so it doesnt cause a problem when watching TV and fan noise is just white noise when sleeping. I like the timer on the remote. We set it to run for a couple hours when we go to bed then it turns off automatically. Installation was easy too. No framing involved! I would definitely buy this again. June 18, 2016
Rated 1.0 out of 5.0 by VERY VERY Noisey The fan works as described, however, it is so loud that it will drive people out of the house. We had a 36" whole house fan and it was not nearly as loud, we went with the Master Flow after seeing it on "This Old House" because it had the R39 insulation. I read reviews before I purchased and was aware of a noise issue. We set it up on a bench before installation and loosely wired it and started it up, the noise level was acceptable. Installing the unit during construction, five months later the weather called for us to start it up and get the benefits. It is too loud to sleep with and too loud to have on and have a normal conversation. NOT A GOOD VALUE, I AM IN THE PROCESS OF ATTEMPTING TO RETURN IT. June 8, 2016
Rated 4.0 out of 5.0 by Great exhaust fan. Great product. re purchased as a replacement. The prior unit had manual controls. This new model has all electronic remote controls. Still pulls air really well but I really preferred the manual control of the prior unit. May 12, 2016
Rated 5.0 out of 5.0 by Easy install and beats expectations I have installed 4 of the 24" whole house fans in various homes and have always been hesitant in installing this fan due to the increased cost and poor reviews. At the insistence of my wife we decided to use this fan and if it didn't work we could easily install the full 24" fan. The house we live in is 101 years old and is lathe and plaster and after the framing out the hole the instillation was EASY. This unit is not silent but it is about 40% quieter than the 24" whole house fans without having to cut any joists. The fan works great and looks great. If you are looking for a QUIET solution for cooling, use AC, if you want a cost effective ambient cooling solution this fan is great and although it is not quiet it is more quiet than other comparable solutions June 29, 2014
Rated 1.0 out of 5.0 by Sounds like a jet engine Yeah it moves air but it's so loud we can't stand running it. Can't talk or watch tv in the house when it is on. I have two units installed and now will have to replace them. The problem is that the motor mounts flush with ceiling and not up higher in the rafters like the quiet cool products. Save your money and go with quiet cool instead October 17, 2015
Rated 2.0 out of 5.0 by Would not have bought it if I could have found something better The fan is EXTREMELY, repeat, EXTREMELY noisy and in balance, does not move much air. I grew up with a 5' louvered attic fan, and while [less] noisy, would suck your socks off while lying in bed. Papers would fly off the desk, instant cool air and no more hot house. This fan won't move any paper; heck, it would barely move smoke. However, if left on for a prolonged period of time, it will finally make a difference. Don't bother until the outside (ambient) air temperature is at least 8-10 degrees less than inside. If you are worried about hearing ANYTHING going on inside your house while the fan is on, FORGET IT. You will hear nothing except exceptional noise. The TV has to be turned up by 1/3rd just to hear it in the bedroom, even though the fan is down the hall. The good news is that it seems to be well made, works as advertised and the RF remote works well from just about anywhere in the house. The little lid opens and closes obediently before and after the fan begins blowing, and the second speed (actually just fan # 2 coming on) does not double the noise.... only increases it by about 40% by my estimate. Physics would dictate that airflow doubles when the second fan is on, but I can't tell that much difference from only having one running. The four hour timer works well, but will wake you when the fan noise finally stops..... I am not disappointed that I bought it; I just wish something better were on the market like in the old days.

Rated 4.0 out of 5.0 by Works Great but is Loud Installation was easy and quick. The fan works great cools the house down quickly but you need ear plugs when you get within 10 feet of the fan even on low. September 1, 2015
Rated 4.0 out of 5.0 by not as quiet as they say It was easy to install. and it is nice to have it sealed up above. So far the only problem we have had is it is not as quiet as they say it is. There is still a roar that most whole house fans have. September 22, 2015
