Rated 4.2 out of 5 by 56 reviewers.
Rated 4 out of 5 by evaluating performance I installed this Power Gable Vent 1 week ago and the product is operating smoothly. I am going to evaluate its performance over the next two months or until the hot weather breaks; whichever happens first. I will then post my results here. I realize that a comprehensive comparison might take up to 6 - 9 months but if the product performs as it says it will, (and as well as others have said it will), then I should see positive results in energy used to cool my house, how often the current system cycles on / off, etc. The fan installed easy enough. I used a section of 1/2" b/c plywood (2' x 2') with a diameter hole cut-out equal to the diameter of the fan housing, (about 15.5"). My frame was (2) vertical 2' x 4' flat side down against the plywood 24" apart OD, (see photo). I will add 2 horizontal pieces to block-in. I used 2" wood screws to attach to T1-11 (both sides) to pull up tight. I wired into an existing 20 amp line using 12-2 romex. Helpful hint; if you are working by yourself a pulley mounted into soffet rafter can be a handy way to ease louver up to your position. August 27, 2014
Rated 5 out of 5 by Excellent Fan I purchased this fan from Home Depot because I had a similar fan from the same Company years before. My old fan quit working after years of service and I never had a problem with it. The installation was easy because I already had the wiring done. My attic is very small and its hard to move in the small space. I found that if you remove the three bolts from the Shroud the Motor & Fan Blades come out. (Do not drop the Motor & Blades for this will bend them and cause vibration) The unit is now much lighter and therefore easier to screw to the Gable. Once you have the Shroud in place you install the Motor & Blades back into the unit. Make sure the three bolts are tight and then connect the wiring. I am sure it will be years before I need another fan because the old Master Flow lasted for yeas. July 16, 2013
Rated 5 out of 5 by Installation was easy and straightforward; works great I purchased this fan yesterday and installed it today; so this is more a review of the installation and my initial impressions, rather than a review of how the unit works over time. Installation was completely straightforward; though I did have to install cross braces because my studs were too far apart. The wiring was also straightforward. If you have ever done even a little bit of home repairs you will find it simple. Once I was in my attic it probably took me 20 minutes; and most of that running wire and tapping into an existing line. The unit seemed mildly noisy right next to it, but I could not hear it at all in the room below. There was a vibration at the beginning; but it turned out that the metal electrical sheath covering the wiring that led from the unit to the thermostat was resting on the fan housing, I bent it out of the way and the vibration stopped. The thermostat seemed to work perfectly. I tested the air with a regular thermometer right next to it and it seemed perfect. I mated the unit with the master flow gable vent. They open from the air pressure from the fan; seem to work ok but they don't open all the way; just about three quarters of the way (I think by design). It had the effect of directing the air downwards out side; you could tell it was working right because standing underneath it felt like someone was blowing a large hair dryer on your head.

Rated 5 out of 5 by Excellent SUPER QUIET!!! We have had other attic fans in the past and they were pretty noisy but they worked so we figured it was just part of the compromise...WOW this thing is REALLY QUIET...the only way I know it was running is if I looked at the vents and they were open or if I went half way up the stairs in the attic. The thermostat works great. As a precaution I put some tape and padding on the power cable coming off the motor because of past experience with other fans where the vibration actually broke through the armor retrospect I don't believe this is necessary. This fan runs so steady and quiet I don't believe it will be an issue. Installation was EASY, the hardest part was running the wire. If you are thinking about this stop thinking and do it...remember in the summer that attic can get to over 150 degrees and at night that is like having a heavy blanket on your whole house...these fans really bring the temp in the attic down and make it easier for your AC's to cool you down. My attic is 1,200 SQFT... I might have another one installed next year to give me some additional air movement. Not necessary but if I can and it makes sense I might. August 21, 2013
Rated 5 out of 5 by Good product Replaced a 30 yr old fan. This fit the old opening so it only required removing the old unit and installing the new one, no modification to the gable wall or vent lover already in place. Works great! August 19, 2014
