 Ms. Carrillo,
Thank you for asking. Fan has been installed and we are already enjoying it.
Yes, it is powerful...just with a look you can see the difference vs a Lowe's fan.....I know I returned one after I decided to purchase yours.
Also, it is quieter than the old fan and from what I can tell and feel....there is a reduction of about 5 degrees cooler in the upper floor
 
Thanks,
Daniel

This fan was exactly what I have been looking for. I went to the Home Depot and Lowes they do not have a quality fan like The German Attic Fan. Very quiet compared to the old Home Depot Fan.

Hi Brad,
Regarding the fan:
It's so quiet that I don't even know it's there.  I used to have a fan from Home Depot that was quiet too.  It turned out it wasn't working...someone had installed it on a rheostat instead of a thermostat and the control had burned out years ago.
The gentleman I hired to replace the old fan with this new one had never seen anything like it.  He was extremely impressed by its quality: its balance, silence, the way it was housed in an easy-to-mount box, and the good thermostat with a long enough cord to reach and install right next to my attic access.
In all the years he's been doing work on homes--and he's quite an intelligent guy--he had never thought about blocking off the rest of the fan's vent so that the fan would cross-ventilate from the opposite side of the house and cool the whole attic.  So, using the same idea, he also blocked off another vent near the new fan. Now my whole attic will be cooled instead of just over the back bedroom.
Brad, thanks for doing the thinking on that cross-ventilation and explaining it on your website.
You're generous with you're good ideas and the effect is going further than your hometown.
All the best to you.

 Brad--

I have several comments.  The German fan is far quieter and better built than the one from Lowe's which costs 3 or 4 times less.  I actually bought and installed one of each.  My house is a split-level with two completely separate attics, so I put the inexpensive noisy fan in the end of the lower attic over the carport, where no one is going to mind the noise.  The quiet fan is in the upper attic over the bedrooms and I simply can't hear it. 

Your instructions were very helpful.  I made sure that I had sufficient area of venting before installing the fans, and I did a very good job of preventing air return around the fans, so I suspect the fans are operating  very efficiently.  My most recent electricity bill was slightly lower than average, but that doesn't tell us much, because the weather was unusually hot.

We love our new attic fans!  They are quiet and efficient. I hope they outlast the cheapies we've purchaced in the past.
