BRAVO Haier--YOUR Serenity Window Air Conditioner is the Cream of the Crop and Incredibly QUIET !!!
The Haier Serenity ESAQ406P 6050 BTU Window Air Conditioner is easily the best Window Air Conditioner that I have ever owned. My main reason for purchasing this Window Air Conditioner was the claim that it was the most quiet window Air Conditioner on the market today. I had been using a Keystone 5000 BTU Window Air Conditioner that was listed three years ago as one of the 10 MOST QUIET Window Air Conditioners on the Market in 2013 by a respected consumer testing and marketing publication. The Keystone was quiet on LOW setting but on HOT days when it had to be set on HIGH the Keystone was noisy. So noisy in fact that I could not hear people on the phone or watch TV unless I was at least 20 feet away.
The Haier Serenity ESAQ406P 6050 BTU Window Air Conditioner which replaced the Keystone was actually more quiet on the HIGH setting with the compressor running than the KEYSTONE was on the LOW setting with the compressor also running. I tested the Haier Serenity by running it on HIGH setting with the Compressor on against 6 other ACs set at LOW with the compressors on using a decibel meter. In every case the Haier set on HIGH was more quiet by 11 decibels or more than the other ACs set at LOW. In fact I could not find another AC that could even come close to the Haier for quiet operation. Simply stated, there does not seem to be any competitor on the market today that even comes close to the Haier Serenity for QUIET Operation.
The Haier Serenity is very quiet on the HIGH setting and I can not really even hear it running on the LOW setting. The room I use it in is 20 feet by 20 feet with a cathedral ceiling and there is an adjoining room that is 16 x 14 feet with a flat ceiling. The Haier easily cools the entire 624 square foot area on the LOW setting even on 90 degree days. I set the thermostat at 72 on LOW fan setting and the Haier cools the room to the level that I like.
Installing the Haier was a breeze it took me under one hour and most of that time was taken up in removing the old Keystone Window Air Conditioner. Make sure when you install the Haier that you tilt the AC unit a little bit towards the outside. That will prevent water ever dripping into your home indoors. It should be noted that there is a drain plug on the Haier and according to Page 23 of your Instruction Manual it is okay to remove it and allow the unit to drip outside. I did in fact elect to remove mine because I live in very humid Western Pennsylvania and I did not want a lot of water sloshing around inside the unit. The plug is located on the right side of the unit when you are facing the outdoors side of the unit near the right outside far corner. When I removed the plug after running the unit only 2 days there was over a quart of water that came out immediately.
I like that the Haier Serenity ESAQ406P blows the cool air upwards and not directly forward. It is much healthier and much more quiet to send the cool air out in this direction. I do not ever get chills or cold pockets with the Haier--that often took place with the Keystone.Haier uses "cross-flow technology" that effectively makes the fan sounds and blowing air less noisy. The Compressor is actually wrapped in a blanket to reduce the noise you hear.
If you look closely you will see that the two vents on the Haier can actually be adjusted down so that the air is blowing up and forward from the unit at about a 45 degree angle. If you use that position you will maximize your cooling effectiveness. The only other position is more upwards at about a 75 degree angle and will be less effective.
This is a truly exceptional Window Air Conditioner!! It amazes me that there are 29 negative reviews. I decided to carefully examine those negative reviews and found that over half of them were not from Verified Purchasers. Some even sounded made up and were so short that they were useless. The 12 or so negative reviews from Verified Purchasers claimed the product was damaged and for reasons that seem mysterious they did not return the AC for a replacement. All I can say on that is that AlumiGogo is an Outstanding Company that has NEVER given me a problem in returning a damaged item for a new replacement or full refund.
Haier has in essence taken the old Window Air Conditioner known for the unwanted excess noise and set a new benchmark for Window Air Conditioners that other Manufacturers should follow. No one really wants an Air Conditioner that is loud and noisy and interrupts your life indoors. The Haier Serenity ESAQ406P is truly whisper quiet even on the HIGH setting. It is by far the most QUIET Window Air Conditioner I have ever experienced or tested to date and it has been one of the most rewarding purchases I ever made! I truly and without hesitation recommend the Haier Serenity ESAQ406P !

like you had to read tons of reviews from people ...
First of all, I think you need to know that I live in Southern California, so my demands are year round. Having said that, you will understand the date of my review is appropriate, but also more applicable than you might expect. I have gone around the bend trying to find a window AC for my study. I've been to Home Depot and Lowes on several occasions and settled for the usual Frigidaire, and LG units. They failed, got loud and eventually within a year wore out. My study is upstairs at the warmest corner of the house, which does not have air conditioning whatsoever. This means that this room needs a heat pump working the whole day as heat rises and collects here. I, like you had to read tons of reviews from people that proved to be no help.
I finally came to this air conditioner and tried to compare three units, this one, the Frigidaire 6,000 BTU 115V Window-Mounted Low Profile Air Conditioner with Full-Function Remote Control, then the same conditioner made by Crosley by Frigidaire Low Profile 6000 BTU Window Air Conditioner CLP06EHQ1. The last 2 were too big- wide for my window and appeared to be just as loud as my LG unit I just gave back.
There is a lot of chatter about the Haier (Hi-er) brand, and the serenity line. Most of the reviews trash the dB levels, but they would be wrong. I measured the dB with my phone app, and the LG had significantly louder sound, almost double.
But the killer is that the Haier is not only quieter, but conditions the air with a combination of fan modes, all of which are quiet. From room ambient sound levels at 44dB, the fan comes on at 55dB, and the motor kicks in at 63 dB. Remember the beginning levels are already at 44dB! But these are levels standing inches away from the unit. When you come away 3 feet, the sound for the fan goes down to 46dB, when the motor kicks on the level goes down to 55dB. When I speak into the phone at conversational level it is at 71dB. Therefore, you can read, talk on the pone, or watch the TV without even knowing the airconditioner is on!!!!!
My next step is to get some neoprene foam rated at 30+- density to cushion the vibration and deaden the sound even more.
Note: I had to tuck foam pieces against the vent hinges to keep them from vibrating, and a couple strips inside the front cover to press against the filter to keep that from vibrating as well. You can't see them and they dont interfere with the function.
Lastly; the air conditioner is very accurate. See the pictures and you will see when the unit turns on- it is only off by +- 2 degrees. This is important because if the temp gauge is off more than that- it will stay on for longer than necessary and turn on at higher temps. If the gauge is +- more the 4 degrees this means that it probably will not be efficient. This is really important because when the unit (compressor) works harder than it needs to, then it will wear out much faster, and never keep up with rising temperatures you want. You will get a noisy compressor and vibrating mounts inside the unit will begin to rattle.
The only complaint I might have is that the front comes out from the window mount about 6 inches. This is the front and is designed with sound deadening foam. This extra space is lined with foam and acts as an air basin from which the cool refrigerant coils can be positioned further away from the outside heat pump and sound. This is a very nice trade off all things considered. I don't need to worry about that extra space coming into the room anyway.
This is the best little air conditioner I have ever bought. The research paid off.

Finally, I can run the A/C and sleep too.
Bought this in the winter! The previous window A/C that came with the room I rent was good at cooling but horrifically LOUD!
The sound when the bearing are out on a fan. Couldn't talk on the phone, sleep, or even watch TV with it on.
Today's the first 94 degree day so had a chance to run it. In quiet mode it's spooky quiet. But that speed was too slow to quickly cool the large bedroom. High speed is louder, a little distracting, but...I did fall asleep with it on high. Medium speed is perfect.
It did start that horrible compressor undulating vibration sounds. Remedied that by unfastening the front cover and then just lightly placing it back in position without snapping it in fully. Now....it's very quiet.
Update 8/6/2017: Definitely had a chance to test this unit out with some very hot days. I find that it takes a good 2 hours to cool down a 90 degree room at 300 sq. ft and 9 foot ceilings. I put it on Auto mode and energy saver. About the 3rd hour the fan slows to medium and then about 30 minutes later down to slow. Slow fan, and super quiet, is the norm from there on. Very quiet and cycles on and off as it should. My best advice, if you don't want to wait for the 2 hour cool down is to raise the temp setting while away, then lower it upon return. This will cut cool down time by about 60%.

So far, so very good!
I just got it installed and it is really, really quiet (even on high). It's still a window unit so it's not going to be central A/C quiet, but it's by far the quietest of any window unit I've ever owned. It hasn't gotten really hot yet so I can't say for sure that this whisper quiet unit will be able to cool like my older 'blow your toupee off' unit did, but I hope it delivers. My only complaint is that it sticks out into the room quite a bit more than the previous unit I had in the wall. It sticks out a good 5 inches from my wall.

Lives up to its name "worlds quietest AC unit"
I bought this 100% for the reviews on being quiet. I have a 400$ unit that does 12,000 BTU and a 90$ unit from walmart that does 4,000. So i have had my fair share of "cheap" units, so this purchase was to finally compare this unit with the cheaper units.
First this is definitely quiet.
Secondly, i think this truly is a 6K BTU unit. On high very cold.
which is the fan doesn't go really high. Now this is mainly because the lower the fan the quieter the unit, and they need to keep the title of "worlds quietest AC unit" so they didn't make the fan too high. However, even with that said, i will definitely purchase another! I do like my room to feel breezy so take this with a grain of salt.

Not quiet as a mouse, but pretty darn quiet!
While I do wish that the package had "this side up!" written on it, as FedEx delivered it on its side, I simply let it sit correctly for two days (to be completely safe, although the instructions say a few hours is enough), and started it up without any issues. It took a little bit of work to get rid of all of the vibrations, but, that isn't the air conditioners fault. Lucky for me, another reviewer here mentioned an idea, which helped me out a bit. I ended up taking their advice and wedging some paper in the air filter and I also wedged some paper between the metal guard that holds the top sash in place and the sash. To really crank the sash down on top of the unit, I used security locks that you thumb screw into the window frame while pressing down the window sash fairly firmly down onto the unit - this seemed to help with vibration as well when the compressor came on.
I will say that the fan on quiet is darn quiet. I use this in an office with 2 running PCs and 3 running laptops, so I already have some fans going at times, and I cannot even hear this over them. When the AC compressor turns on, there is a hum, but not very annoying or loud, especially when compared to a previous unit that I had.
I would definitely recommend this unit to anyone looking for a quiet unit. Do remember that it doesn't run silent, but, with a little extra work you can reduce additional vibration as well and make it as quiet as possible.

Well I'm so glad I went to the trouble of seeking out this ...
This was my third attempt at buying an air conditioner for my office. It is only 10 x 12 and the only window that opens (and the only workable place for my desk) is about three feet from my face. Well I'm so glad I went to the trouble of seeking out this unit - and it was a lot of trouble. I finally went with OJ Commerce, despite some forecasted shipping dates that were far enough out to make me worried about sweltering, and, wouldn't you know it, the unit arrived three days before the earliest forecasted arrival date. Thanks so much!
In any case, the unit is shockingly quite. Again, three feet from my face. I could easily carry on a conversation in person or over the phone. I love the unit's lower profile because it doesn't block too much natural light. I also love that the air is sent up, rather than out. In a pace less than 250 square feet, who would want to be frozen. I am also impressed with what looks like reasonably good quality - so hard to find these days. And it's definitely one of the more attractive units around.
Bring on summer!

A meaningful improvement in noise reduction--
First, I will say I am comparing this a/c to the same brand 5k btu window a/c.
This one is far quieter than the Haier 5k that I had used in this same window, next to my big screen TV. It cools very well, and allows me to keep the TV at 'normal' volume levels (TV was set to volume of "50" with the old a/c, now set at "28").
The cabinet vibrates in sympathy with the condenser motor at certain speeds, which is not obnoxious, but disappointing. The 'auto' fan setting appears to allow a continuously variable fan speed, moving faster or slower as the cooling demand dictates. The fan speed selector offers set speeds only unless one selects 'auto'.
If this trend in window units expands to other brands and can be improved upon even further (quieter still), I am tempted to abandon my plans to install a mini-split system. This is a meaningful advancement in noise reduction at a reasonable cost. Efficiency is as
good as any window unit, but is lagging compared to the mini split systems.
I give it one star reduction for the cabinet vibration noise.
Based upon other reviews' criticisms, I will add that I did not find the unit to be any heavier or harder to install than any other unit (I am
using 4 in my home).
Update 8-25-15--I received a kind note from a fellow buyer of this unit, describing how he solved the cabinet vibration noise cheaply and easily. It worked!!
Here's how I did it:
Purchase a window air conditioner foam filter (the 'cut to size' type) and place it in front of the current factory filter behind the front panel--i.e. between the front panel and the factory filter. This places a 'pad' to quiet the OEM filter from vibrating. That is to say, it is not the cabinet that was vibrating, but the brittle plastic OEM filter frame. Problem solved--quietest a/c I have ever owned--even on 'high'.

Overrated! Bought this Haier 'quiet' ac after buying a ...
Bought this Haier 'quiet' ac after buying a LG 5000 btu ac but I thought the LG was too noisy. Comparing both Haier and LG on low fan speed Haier ia indeed quieter, but not by a lot. Using a sound meter on my samsung phone the difference between the two are merely 4-5 db (haier is about 56 57 while LG is about 61 62)
But I do have to mention that the noise from haier is less disturbing than LGs. It may be because haier's is more of a wind noise while LG ia more a mix of wind and compressor noise??
But the problem is the air flow of the haier is so much weaker than the LG. When I put my forearm over the vent the LG low fan speed feels the same as Haier high fan spend; even though the spec says otherwise.
Another thing is the coolness. Turning both unit to the coolest setting and LG blows much cooler air than haier!
So, in my opinion this haier serenity ac is way overrated and not worth the premium price. I got the LG for $127.

Baseline noise level is really good. Random sporadic noises are not.
Default noise level is pretty desirable for trying to get to sleep in a bedroom, however, it's the random clicking and other sporadically inconsistent noises that are more disrupting than the overall volume. I've taken to sleeping with foam earplugs in the summer when it's in use.
I tried troubleshooting the issue extensively, ensuring the unit was properly level/tilted towards the outdoors, etc., but nothing makes a difference in the sporadic clicking noises while the unit is in operation.
The "Auto Quiet" mode is a complete joke. The low/medium settings are quieter than the "auto quiet" mode.
But overall I'm still happy I own this. I just wish it was more consistent in the noises it produces.
