CUSTOMER REVIEWS

Rated 4.5 out of 5 by 35 reviewers.
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 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 So far, So good Just took the fan out of the box for some preliminary testing. Here are my thoughts so far: Well built unit, heavy gauge steel for dome and "duct". Assembled with bolts, not sheet metal screws. Dome supports heavy duty. Fan blade is "3 wing" type with the blades riveted to the hub. Much better design than the 6 blade stamped steel fan used on cheaper models. Fan runs quiet with decent airflow. Electrically the fan uses the PVM105 1/7hp motor. Motor is rated at 1050rpm/1.9amps. Motor is heavy duty PSC design with a 10uf capacitor. PSC motor designs are much more efficient than the cheaper "shaded pole" motors. I hooked it up to a "kill-a-watt" and the Motor Amps read 1.51A, Wattage 163W, Power Factor .88. Power use for a month based on 10hr per day run time would be 50kwh/month. If you pay 10 cents per KWH it cost about $5/mo to run the fan. IMHO the extra $15 over the entry level fan is well worth it. In addition to the better fan blade/motor you also get a paint job. I'll write another review once the unit is actually installed on the roof. July 22, 2011
Rated 5.0 out of 5.0 by Works as advertised Installed as a vent in my man cave. Had an electrician set up a switch to turn on anytime. Sucks the cigar smoke right out. March 3, 2015
Rated 5.0 out of 5.0 Quiet, and makes a noticeable difference This fan is VERY QUIET!! and moves a decent amount of air, I bought this based on reviews here, vs the one at the big blue box place. Someone on that review site mentioned how loud their unit was, and that they exchanged it for this one sold at the Home Depot. They mentioned that the quality of this fan was significantly better that the blue box one. If you look closely at the pictures on the two websites, you can discern a difference. I bought this fan to install in my recently purchased house that has a hip roof. I went up into the attic a few weeks ago when the temp was in the upper 80's outside, and my attic felt like it was 120F. Someone mentioned that this unit does not come with a template. That is technically true, but......The cardboard packing inside the fan box is cut to the shape of the round inlet. All I did was take that piece up on the roof with me, and it worked like a charm. Wiring the fan was easy. You will need a cable relief/ connector to run your romex (or in my case conduit) to the box that contains the thermostat. The cover pries off. No screw removal needed (but the instructions do not indicate that- and when you are working in the attic, every minute counts). The thermostat box is not too tight, and they give you plenty of wire to work with. Getting the cover back on was a little bit of a chore (in a hot attic- before the fan was running) but you will want to make sure that the U shaped cover piece's tiny lips go over the part with thermostat attached. My fan seems to be perfectly balanced, and there is no vibration felt when touching the unit. The unit is very quiet. When I climbed out of the attic (before replacing the attic access cover) I could not hear the fan while standing on the ground. There is no way you will hear it with the cover in place, I will have to crawl up in the attic occasionally to make sure it is working. I guess I will know it is working, because the temperature in the upper level of my house should be much more comfortable, and hopefully my utility bill will decrease. August 24, 2013
Rated 5.0 out of 5.0 by Easy Install & quiet operating I purchased two of these for the home we recently bought in Florida. The home had two pre-install units that had the motors locked due to age. These new units had the same diameter (15 inches) for the required opening as the old units. Although the old motors were about half the size of the newer heavier duty motors, the brackets on the new units were shorter. This allowed me to reuse both the existing roof opening stacks and the caps from the old systems. My own install was simply a matter of climbing on the roof, removing 3 screws on the old top hat covers, and then removing the 3 fan bracket bolts on the side which retained the fan motor assembly. From that point I lifted the old fan assembly out, reached in and disconnected the wires, reconnected the new fan wires and slid the new unit in replacing the previously removed screws/bolts. As a side note, even though the install was made during mid December the thermostat controls on the new system (set at 95 degrees) have already kicked on automatically. The fan motor was very quiet and if I had not been sitting directly under one as if started I don't believe I would have known it was operating. The attic fan's operating noise can best be noted as quieter than a refrigerator. December 29, 2014
Rated 5.0 out of 5.0 by One heck of a value This fan is a great value as it includes the thermostat and a 5 year warranty! Masterflow is a GAF brand. The unit is all metal, I don't think their is a piece of plastic in the whole thing. I would say the sheet metal brackets that connect the dome to the main chassis seem a little flimsy, but I guess they must be good enough. Seems to have a nice motor. It's not loud either. Has a nice large flashing. The instructions are very good which helps a lot with installation. Not only is there an extensive FAQ section, but they also provide detailed tables to help you determine the size and quantity of fans you need for your application, plus your makeup air vent requirements. Be sure to follow the instructions for a good install. You don't want to go to all that work then have it not work optimally. Be sure to remove some of your soffit vents and check them as I found that all of mine were clogged with environmental filth and had to be replaced. Also make sure that insulation in the attic is not blocking the movement of air from the soffit vents up through the fan. This can and should be corrected otherwise you're wasting your time. I'm very pleased with this fan. What a great value--especially if you have a coupon to apply to your purchase! :-) June 20, 2010
