So I ordered the package on Friday and received it next Tuesday (it could be delivered Saturday, but the order was placed by noon and logistics had to pick it up Monday! I live in GTA area maybe that’s why it was delivered next day after picking up Monday).
The fans are REAL game changer, as I live in a stack house and the AC/furnace almost never cover last floor (where bedrooms are located, hence in Summer it’s like Sauna. It made a difference (at least 30%-50%) achievement, which is very good as the other solution is changing the duct infrastructure.
It’s WAAAAY better compared to other smart registered like (keen and flair) which are recommended by some smart thermometer and also better than many on the internet and Amazon.
The reason is easily that the smart registered recommended by some Smart thermometer are JUST opening and closing the vents but not puling ANY air to the rooms, while this one, it pulls the air from the ducts (either Cold or hot) to push air to rooms where no air is reachable (like in my case).
It’s also better than Just registered fans on the internet, as you can control it remotely and don’t need to depend on Bluetooth or be close to it control it, so you may run it on Max fan speed to pull as much air as you can to cool/warm the room before you arrive (as the max fan speed is very loud especially if you live in quite area), then reduce the fans speed during your sleep or when you don’t want any noise (normal default operation is like running a fan in the room, so if you Rin a fan in the room along this, you wont feel any noise in default fan settings, But I need to run on Max to pull as much air as possible for those exiled rooms on 3rd floor)
It also has Eco mode, which It runs when either HAVC/fan is on and stops when HVAC/fan is off. It also has Auto mode , where you may set to desired temperature and the fan will stop automatically when it reaches this temperature or start again if it exceeds it (in case of cooling)
One other best part, it’s Made in Canada and support also is here in Canada which is we are very proud of and need to support (especially, it really worth it)
Glad to have it!
Very happy with results.
First got two fans for main bedroom on the second floor, that did help with cooling on the second floor, but still a little hot. Got two more for the other rooms on the second floor and that solved the issue, the second floor pulls lots of cool air and stays cool on the hottest days.
I haven’t used it yet but the installation and the hook up to my nest was simple ! I turned on the nest and lowered the temperature so it would turn on and the cocoon turned on beautifully and the ac came through perfectly! I’m sure the heat will work the same.
