Rated 5 out of 5Â by Tommy 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.

Rated 4 out of 5Â by Handyman 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).

Rated 5 out of 5Â by Bob571 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.

Rated 5 out of 5 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.
