OP here...I just scheduled an install for my similar size home. Getting the Trident Pro 7.0 with an out the door price in the $2k neighborhood. I do need two additional roof vents which will be extra cost as well. I did ask about the newer Stealth line which is more efficient and expensive, but was told there was a higher motor failure rate so decided to pass on that one. Also, the WiFi controls and apps are apparently not ready for prime time yet, but could be retrofitted in the future. Hope that helps!
Thanks for the link. These guys were by and far the cheapest price I was quoted ($1795 out the door for the Silent-X 7.0) Installation proceeding next Wednesday. Will update on how things go once completed.
Do they make one that exhausts out of a gable wall in the attic? I've got a sealed, conditioned attic, so it doesn't help to exhaust living space air into the attic. I saw some of QC's units that exhaust through the roof, but they use a lot more power than the others -- no ECM motor -- and I'd rather not add a roof penetration.
For those proceeding with installation and getting the RF remote, I suggest getting two. I keep one downstairs and one upstairs. It can be mounted on the wall as it is similar size to a typical wall switch, but I just keep it on the table next to me.
I have the rf remote on mine and the instructions say only one can be paired to the unit. If you can indeed pair two please confirm so that I’ll get another for mine. I only recently went with the rf because I invested about a grand to get the WiFi units for mine installed years ago and it never worked stably.
I have (2) of the RF wall looking remotes, one upstairs and one downstairs, and have zero issues with it turning on, or off, or changing speeds etc. EDIT: two of these:
You would think in 2020 they could build a more . . . attractive device. That thing literally looks like someone took a wall switch and put it in a plastic box.
They do make gable fans, but I have no idea how effective those are, relative to other gable type fans.
it is meant to mount on a wall and look like a 1 gang box. Definitely not designed for a table top aesthetic.
Installation completed just a few minutes ago. Overall took 2 guys about 90 minutes to get it installed. Perhaps I'm just a quiet freak, but the "Silent" fan is louder than I expected. I was expecting to not hear it at all on the low setting, but it is audible.
its not silent, but how much you hear it depends on the attic, etc. Try it for a week or two, and if you still are unhappy with it, call them back and see if they can re hang it to make it quieter. In my case, they installed it, and it was louder than I thought it would be, and after a couple weeks called them back (quietcoolguys). They said "sure lets get you scheduled for the crew to come back and take a look". a few days later, they came back and moved it to hanging between a slightly different pair of joists. Made a difference, and it was quieter. The first crew didnt hang in there because it was over a bedroom, but the bedroom is a spare bedroom so I didnt care if it was a bit louder there, as it was quieter in my master and less echoing downstairs. It ends up sounding like white noise at night, and I got used to it after only a couple nights, and I am a light sleeper.
Is the noise on low more from the motor harmonics, or from the air whooshing through the grille and flex duct? Ar the end of the day, pulling a few thousand CFM through a 16-18" duct is going to have some noise, though to me it's more of a not unpleasant low white noise...
It sounds more motor noise, not a "woosh". I'm going to have to do some more testing and get more data to make a conclusion and decide if the sound is going to be tolerable long-term.
Its a low motor growl, at least in my case. I found the utility and operation of the fan made such a difference in the interior comfort of my home without using my AC, I wanted to give myself a chance to acclimate to it. I mentioned a couple posts ago that it still seemed a bit loud to me but then I had them re adjust / re hang it, and it was better. Not "silent" by any means, but it turned into a white noise type thing that I got used to pretty quickly after they adjusted it.
So just had my install done, 5.5X Stealth by QuietCool Guys. They were excellent. Great communication, wore masks, cleaned up very well any drywall mess. Install took a grand total of 30 minutes, and 5 of that was me paying the bill. I'll post some updates later. I put a EcoBee temperature sensor in the attic 3 or so weeks ago to get a baseline of attic temperatures so curious to see how this will effect it.
So first night/evening using the quietcool went pretty well. I think my part of San Diego is still a bit too humid to be ideal to be running the fan solo. We left for dinner when it was still a bit too hot out, once we came back home we opened a few windows down stairs and turned it on high, coupled with the nice breeze we did notice a very rapid 5 degree temperature drop (outside 74, inside 79) and stayed about 5 degrees warmer than outside for the rest of the evening. Overnight dropped it down to low and ran it for 4 hours with the bedroom windows open. One thing I noticed that was interesting, the Attic while it cooled down very fast in the evening when we turned it on actually stayed warmer running the quietcool fan than without. Running the fan overnight actually kept the attic warmer than on previous nights. Back to the humidity concern House went from around 45% humidity up to about 61-65% humidity. That is a bit too much, and not the fault of the fan but just the San Diego climate. It wasn't too bad in the evening, but i'm actually running the AC again this morning to dry out the air so its not warm & humid in the house during the heat of the day. Overall, I can see its utility and plan to keep using it too supplement/augment our AC but I do feel a little constrained by the humidity concern.
