Quieter than others and easy to set up
By DPS5099 on Reviewed in the United States on July 1, 2022
12,000 BTU Unit - This is the 3rd floor model air conditioner I’ve purchased and I love it. The packaging was very sturdy. Heavy cardboard box, thick styrofoam padding and nylon straps outside the box protected the unit which was delivered in perfect condition. Unpacking was a breeze. One of the things I love about this unit is the exhaust hose is a heavy, more rigid plastic material that easily snaps into the unit. Other units like this came with flimsy exhaust hoses that needed to be stretched over the exhaust port. I always ended up buying heavier hoses and attaching them with large steel “worm” clamps. Not necessary with the SereneLife unit. The window insert is not as tall as others so it allows more visibility out the window but because of the size and characteristics of my window I had to raise it with a 1” board cut to fit the sill. I also had to trim about 4” from the slide out part for it to fit in my sill. Not a big deal. Took me a minute with my table saw but could easily be done with a hand saw. On a positive note, if you have a very wide window this will fit with no extra work. Also there is a tab to lock the slide expander j to place. I’ve never seen this on previous units. A convenient feature. Now to the important stuff - cooling the house… The unit easily cools my L-shaped living / dining room area as well as the attached kitchen. That’s about 1000 sq ft.. I do have 2 ceiling fans running at slow speed to help circulate the cool air. It is MUCH quieter than previous units I’ve owned. There is a feature that allows the cool air directors to slowly oscillate up and down. I don’t use it but you may find it beneficial. It has a sleek appearance that is aesthetically pleasing. The price was very reasonable for such a powerful, effective air conditioner. Now I’ll mention a few negative issues… 1. There is no screen to cover the outside end of the exhaust port. Depending on where your window is critters and debris can easily find its way into the hose. I’m going to make a screen cover for it. 2. The remote is pretty flimsy and there is no display. My other units had remotes that displayed the same info that is in the unit display. Also the lettering of the functions of the remote buttons is really tiny. 3. As stated, the window unit is very low profile and very wide. Depending on the design of your window you may have to raise the window insert and/or trim the width of the slide expander. All easy things to do but know that it’s possible. All and all I’m very pleased.

If you are a fan of blowing money on useless things, they've got just the thing for you

I bought this at the end of July 2024 when my upstairs HVAC unit went out and I needed some way to survive the summer heat. It was...ok. First, I had to have someone cut the plastic window insert to fit my window because the 'adjustable' part actually blocks the exhaust flow. Also, the way it adjusts also makes one side wider than the other so you have to fill on the gaps with insulation foam. Yay fun. But, I got past it, turned it on and cold air came out so it was good....and loud. So loud. But again, Georgia heat, so I'll be ok. Now, I was only trying to cool one bedroom, which for this size should have been a piece of cake, but it struggled. I survived August and September and then finally put it away in October. So basically I used it for a little over 2 months. Due to unfortunate life circumstances, I was not able to get the HVAC fixed before the temps got warm here, so I decided to use this unit temporarily. It doesn't cool at all anymore. It's basically a very large, very loud, VERY EXPENSIVE fan. Today is day 3 of trying to use it at night. It's not terribly hot here, just a little warmer than I like it, so you'd think it would be cooling pretty easily. Today it has been running in a closed off bedroom for 2 hours and the temperature hasn't moved at all, but yet it feels more humid in the room than anywhere else in the house. It actually feels like it is pulling in the humid air from outside and pushing it into the room. I've had it less than a year, used it for less than 3 months of that time, and it is useless. Edit: The very next day after I posted this review, the unit started having a strange burning smell, so I turned it off. When you turn the unit off with the remote, it shows you the current room temperature. It showed the temperature at 86°F, when it was only 70°F. I then unplugged it. Tomorrow, I'll be buying a different unit by a different company.
