SereneLife Small Air Conditioner Portable 14,000 BTU with Built-in Dehumidifier - Portable AC unit for rooms up to 650 sq ft - Remote Control, Window Mount Exhaust Kit

So, I originally ordered 2 of these. When they arrived, one worked great, but the other one was leaking all of its coolant fluid out of it. The box was all torn up and there was a spot where the outer plastic cover of the unit was crushed or punctured. The replacement came and was also leaking all of its coolant out... actually it was in worse condition. Finally, the replacement for the replacement came and it was in perfect condition; no leaks, no scratches, no issues. Finally! The pictures are of the first one that arrived leaking coolant.So now that I have the two, the timing is pretty perfect. It's early spring, so some days have been in the mid 80's and some days have been in the 30's. That's just how Texas weather is. I can say that both the cooling and heating is awesome on these things.What took me back was how quiet these things were. Some other reviews said they are loud. Compared to what, I don't know, but mine are super quiet. I wasn't expecting this since this is, essentially, an electric furnace and a/c in a plastic container. My only guess about the noise is that they're comparing the noise it makes to... silence, I guess, or (a common issue with any air conditioner) is that they plugged it up and powered it on soon after getting it. When it comes to anything with a compressor pump that moves coolant (or any liquid, for that matter), you have to let it sit upright for hours before ever powering it on. The compressor is not made to move air, so if the liquids haven't settled properly before operating, you're going to quickly damage your compressor. It might still "work", but it might loud or it may never heat or cool to its full capacity. Same goes for refrigerators.The heat capacity of this was impressive. It takes a moment to warm up, so when it does come on, the compressor might kick on first, then the fan will kick in on low. After a while of running it'll be much warmer than when it starts. So far, the coolest night for me was 34 degrees and I actually had to turn them down from 72 to 68 because it quickly got hot in here. While the heat coming out may not be as hot as the heat from a gas furnace or electric space heater, it moves far more air in general. The heat coming out won't be hot enough to set something on fire like a space heater, but the massive amount of air it moves quickly made me see why it didn't need to be any hotter. The heat these provide are more impressive when I realized they use less than 1000 watts each when they are on heat. Most much smaller and less capable space heaters use at least 1500 watts.This thing does have a setting to use to dry out or evaporate the water it has accumulated. If you don't use the included drain hose and leave the drain plugged, it will evaporate this water off when it fills up. If you use it, what's interesting is that the drain is pressured; it comes out with a bit of force, enough to blow bubbles when submerged. It won't splatter water everywhere, but what's good about this is that it means it won't get clogged up like the drain on most air conditioners.I have been working from home for years and years, long before covid, so I know how important it is to have a quiet room to work in as background noise can not only be distracting, but can get you fired. This thing sits less than 6 feet away and can't be detected on my mic. Again, a working unit shouldn't be loud. It says to let it stand upright for at least 2 hours before turning on. I let them stand for at least twice that time, 4 hours. This might be the reason my units are quiet because once that compressor pushes air, it will never run quietly again if it keeps working.As far as the remote, you don't have to point it right at it for it to work.This, like all portable air conditioners, will create a bit of a vacuum which will pull air into any cracks in your walls, windows, floors, etc. No matter how well your home was built, it will pull that air in from somewhere... kitchen vents, dryer vents, bathroom air vents, etc. This happens because the air that the unit uses to cool the rear radiator, which vents outside, is pulled from the back and sides of the unit. It also pulls the air that it is going to heat or cool through the same area. So only some of the air is coming back out into your home (the air that is heated or cooled), but about half of all the air coming in is pushed out of the back of the air conditioner out of the vent that goes through the window. I'm used to using portable air conditioners, so I tend to build a box around them and put an extra vent near the back and pipe it outside, about half the size of the one going out. That tends to stop the issue and give me far greater BTU value than it is rated at. Otherwise, I just leave a window cracked somewhere near the unit as I am used to having to do this with wood stoves anyhow.

I am extremely happy with my purchase of the SLPA8 AC unit from Serene Life. It works well cooling my 10x10 office with a builder grade 60 x 48 inch southeast facing window. Last summer it was unbearable here (Seattle) with temperatures reaching 100 deg F. or more for many days. Since installing the AC unit I am able to instantly cool the office when needed. I find that I do not need to run it all the time, only long enough to be comfortable... usually 15 to 20 minutes at a time providing 1 to 2 hours of comfortable conditions. I seldom use the high setting as low is quite cool.The unit is easy to set up although the supplied pvc window louver is too short for my window. I purchased a 60 x 6 x .5 inch piece of lumber and used my jig saw to cut out the necessary opening and attached the louver to the board. I also purchased pvc half inch pipes to use in the window track and middle of window keeping pressure on the window and eliminating risk of unwanted guests or air gap. Last piece of customization was double sided half inch foam tape between the board and window edge really providing a gap free seal.The unit is rated at 57 db and seems a bit loud but not disruptive. I have a noise canceling speaker and am told others on my Zoom calls cant hear the ac when it is running. It takes up a bit of floor space but its worth the trade off. I have no problem with negative air pressure it just a tad bit more of a pull to open my office door. I have had no problems with the water resivoir filling up nor have I had any issues with power or electricity. I do have it running on a 20 amp circuit which is nearly 3x what is required (8 amp draw when cooling on high setting I believe). The supplied remote is small and easy to use.. not a lot of functions or buttons so it tends to be self explanatory.I am very happy I purchased the SLPAC8 and would do so again.Great experience with fast shipping via Amazon and arrived in the original box and packing materials.One last suggestion, don't wait til the dog days of summer (like I did last year) as most options sell out quick. No way I was making the same mistake this year!Very Satisfied thus far (nearly 21 days run time).
