Very quiet !! Very easy to adjust thermostat !! Beautiful !!!

Easy install from an existing 20 yrs old attic fan. Since its winter it wont be running for quite a few months. Will have to update review in the spring/summer.

Had the fan installed and then a electrician wire it - fan ran continously at 100 setting at 73 degrees ambient temp. So removed the thermostat and headed to Home Depot to exchange. Don’t expect this will be easy.

Low profile on my new roof and looks great. It does a great job at cooling my attic, it even reduces the heat in the garage beneath the attic. My only complaint is that is a little noisy, a little squeaky. May have to have the electrician come back and double install but a GREAT unit.

Install was as expected, somewhat difficult on metal roof but looks good and performs well. Motor is quiet and pulls a lot of air.

Easy to install, the inclusion of the thermostat was much appreciated and works great!

Very nice and quite no noise very smooth

Super easy to install and already notice a huge difference in the overall feeling of the house without having all that static hot air sitting in the attic. I did purchase a unit larger than my actual attic space to help move air a bit quicker. Unless the house is super quiet and you are in an are directly underneath the installed location you don't even know it's running.

Bought two and had them installed. After electrician wired them only one work. Now I am stuck with one good and one bad.

Installed on a client's house, easy installation and wiring instructions. Would purchase again.

Easy install, great instructions.

The fan was easy to install and wire. However, the problem is it shakes. I have more than enough nails to secure it. I verified all mounting hardware. I have enough air flow from soffits ( my old fan did not rattle). Not sure if the low profile allows the correct air flow out. Will probably try a speed control to see if lower speeds help.

Installation was easy, and fan is effective in cooling my garage.

Master Flow 1250 CFM Weathered Wood Power Roof Mount Attic Fan? Works fine, fairly quiet, but doesn't seem to turn on as much as previous replaced fan.

I bought two, it was easy to install, and my attic was cool in no time.
