Answer: 
This fan is fairly loud, but we don't mind it. Since the windows are open when it's running, it drowns out the noise from outside so my kids can still get to sleep.

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.

Customer Reviews

Rated 2.7 out of 5 by 39 reviewers.
Rated 1.0 out of 5.0 by The first unit that was shipped to us was defective and I had to call the online number and then return it to the store which was a hassle. The re-order was confusing, but finally a week later the 2nd one arrived at the store and I went and picked it up and we had it professionally installed. That evening we couldn't wait to turn it on!!! What a disappointment! Hardly any air movement and the temp in the house went down only 2-3 degrees. I only cracked windows as suggested and still no luck cooling the house down. I have better luck cooling down the house by opening all the windows and doors. The fan is noisy, but that wouldn't bother me at all if it worked as it claims. Out the money for the unit, plus $100 for the installer. I don't recommend this at all. October 28, 2016
Rated 5.0 out of 5.0 by Great fan for the price If you want a quiet fan, you need to be willing to spend more money. For under $500, this fan works great. You need to open windows for this to work. I feel like everyone on here who complains either doesn't know how a whole house fan works, or they're super impatient. It takes about 30-60 minutes to cool the house off completely once it's cool outside. I always rotate which windows are open. I start by opening the windows that the sun is no longer hitting. When the sun is down, I switch which windows are open. This fan was super easy to install. I love that it has a remote, so I didn't install a switch. I can always install one late if I lose my remote. :) September 7, 2016
Rated 4.0 out of 5.0 by Whole House Fan Installation The installation worked out just as the instructions indicated, pretty easy. It worked just as described. It isn't silent but it is a whole house fan. I wouldn't put it in my living room but it works great on the second floor of our house. The remote works great. October 11, 2016
Rated 1.0 out of 5.0 by Did not work as it should My husband decided to wire up the fan before installing it up in the attic and we are glad he did! The fan did not work correctly at all. The automatic door stayed shut while the fan was running and when the fan shut off then the door would open. That is the exact opposite of what it is supposed to do. We returned it the next day. September 27, 2016
Rated 4.0 out of 5.0 by Works GREAT, but is LOUD It works wonderfully, but it is LOUD, even with only one of the two fans on. Just know this before you purchase. September 20, 2016
Rated 1.0 out of 5.0 by Too Noisy - Poor Air Flow I have used this fan for 5 or 6 years now. It is reliable. Did anyone mention Noise? It is unacceptable. Did anyone mention air flow? It is poor. I put a furnace filter in front of the fans to try and cut some noise. Not much use. A better solution for me was to use a 1000 cfm turbo duct fan 12 inch. Hang it in the rafters with rubber tire mounts or mount it on a board and plum it with insulated 12" flex duct hose. My old house had a 12" grated vent hole in the kitchen which I use as my inlet with a 12" flap valve on the 90 degree elbow I used in the attic. The flap valve closes when the fan goes off to keep heat from flowing back inside.The fan itself on mine is mounted on a good size board with 2 by 8 risers topped with 1/4 inch rubber for vibration control.You can then point the outgoing air where you want to. The fan is on the end of the ducting in the attic. I control it with a self shut off timer switch with 5-15-30-60 min and 2 -4 hr settings. If you want to branch off to other rooms with added grates, simply install the grates in the ceiling and probably go to 8" ducting to a junction before the 12". You can barely hear the fan in the attic and it will suck your kid up the vent hole. I checked air flow with a new flow meter. The turbo fan is pulling air in at 200mph on a 50 ft flexible duct. I could not even get a reading on the other unit. Enough Said! July 30, 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 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
