Bests & Worsts Reviews from Amazon

Be aware that this unit has a high pitch whine to it that, in my case, has never gone away. I’ve had mine installed for two years and use it regularly. It’s great for pulling cool air up from the basement but I have one in my TV room, and I like to turn my TV up pretty loud, and I can still hear the whine over the TV. It has two whine levels. If the central air isn’t blowing and it is just the unit blowing air, the whine is one level, but when the central air kicks in and the unit cranks up faster, the whine decibel level goes up and you can hear it winding up as it does it. And I don’t think it is air noise like some reviews claim because when I go outside in the wind, I don’t hear a whine like I do when this unit is turning. So it must be motor noise. It does work well, I just wish they would do something about the whine.........obviously.
