UPDATE July 20, 2020: We had a very hot June and July and have used it extensively to good effect. Then we ran out of electricity for a few days and I ran it on a generator so I could power the air conditioning. I put the car in non-eco mode at maximum power, turned it on continuously and closed the doors upstairs when we were down so it could try to cool the entire house. Of course he couldn't, but he could drop the temperature from a sweltering 90F to 77F and wasn't as humid during the hottest part of the day. It is wonderful. A year has passed and the device still works well and we are glad we have it. FIRST OVERVIEW You can't have everything at once. This device (12,000 BTU) is designed for high-performance applications. That's good in that they didn't skimp on cheap, lightweight materials that wouldn't really cool at rated temperatures and wouldn't last long. Even though this machine is noisy even on low settings, it releases a large amount of cold air with strong airflow on these low settings. The good news in terms of noise is that it's a constant low rumble rather than the very annoying variable rumble that cheaper models will have. However I think if you install this in your bedroom you will have trouble sleeping until you get used to it. By the way, 12,000 BTU isn't really meant for the bedroom, is it? We're talking about a nominal unit of 550 ft^2, so what's that use case? The top of my house is about 700ft^2 and the air conditioner can't cool it down at all. Upstairs in the hallway, at the top of the stairs, is a window where I installed the device. I built a wooden frame to support it since its 75 pound weight would crush the vinyl window. A lot of nasty words were said during installation due to the weight, but the frame I built really helped me do it on my own due to the leverage. The gap sealing materials they provide are very helpful, the best I have seen. A steel bar running across it helps seal and stabilize the unit in the window. How does it work? I used low wattage and directed the vents up and down, hoping the cold air would rush down toward the bedrooms rather than unnecessarily going down the stairs that are right next to them. Weight and noise pay off. A huge fan sends a huge stream of cold air at high speed down the hallway and into the two open doors. A kind of convection is created, which cools the rooms. This surprised me, I thought ceiling fans would be required to facilitate convection but there weren't any. The car just blows out so much cold air, so much that the top quickly becomes saturated. Maybe we turn it on and off an hour before bed because when the sun goes down the temperature isn't too bad in Michigan where we live and that way we're spared the noise. Like I said, you can't have everything, but the sheer power of this machine gives you the choice. PACKAGING: If not already done, place the box face up. After cutting the plastic ties, lift the crate. You'll smile at how thoughtful the packaging design is.
