New, EXTREMELY noisy, with a pulsing quality. We found that propping it forward about 10 degrees solved that. Is that OK to do?

No, it is not supposed to be quiet, it's supposed to be loud, replace it if you think you need a new one.

It is REALLY noisy, seriously I will be returning mine because of that. I had bought for my bedroom but this is unbearable, even the lowest speed generates so much more noise than my old AC on the max speed.

Hi, it wasn't too noisy at all but I returned it and bought an oil heater instead .... A radiator. The reason was because we prefer the "warmth" of an oil radiator

No. I'm already having problem. It started making noise when I increase speed the second week I got it. So I can't use it as I wanted on a daily base.

I purchased a very popular brand and it was very loud. I replaced it w the same one Exact same problem. I sent it back and got this. No noises that I know of, very smooth.

Hi Terry. Good point. Worth asking the seller. I don't know if all ac from them have the same issue. Plus, people may have different levels of tolerance for noise. I couldn't sleep. Maybe it is just me.

ours are not really very noisy, I mean I had louder ones before. I guess this one is medium noisy if that makes any sense...we are happy

I havent installed it yet. My existing was sounded like the bearings were going out so I got one ordered, but it quieted back down. I would make sure that the drain on the bottom is clear so your not getting condensate in the bottom of the fan. If it were a high pitch noise, I would say it is a bearing, but low pitch noises are normally imballance - which could be caused by things like a little rub on a blade, blade manufaturing defect, condensate in the bottom, pluggage on the inlet or outlet, or a slight missalignment. Hope this helps and good luck. Sorry for the late response. I thought this was just junk email from amazon. I havent installed it yet.

hi, I turned it up as much as could( I live in an apartment complex). I did not notice any disturbances. unfortunately I cannot tell what decibels it was.

Mine does not have this high pitch you're talking about, just a loud hum, rather like a window air-condition unit. Since it is in my basement, it does not bother me. Maybe you have a bad unit?

As I have no decimeter the answer is it is not very loud. You should not have a problem with the noise level.

Not so fast people. *Most* of the time this unit is pretty quiet, only producing a very low steady hum. However, it *can* get annoyingly loud (3-4 times its normal volume) where it's sort of vibrating the plastic pieces of itself together. Topping off the water level sometimes helps a little, but most of the time it makes no difference. (It does the same thing right after a fresh cleaning too, so it's not an issue with debris.) When this happens, you can tap it / nudge it / smack it and the vibrating noise will cease - USUALLY. But sometimes it won't. There have been times where I wanted to smash it to bits with a hammer to make the noise stop. The only thing I've found that you can do to quiet it down is to completely open it up like you're cleaning it and pop the pump assembly loose and reseat it. It helps to barely press the pump down onto its suction cups, which is now what I do when I clean it. Before, I used to press the pump down firmly, which seemed logical but only increases the chance the unit will vibrate loudly. It seems like they ought to have put rubber seals between the plastic pieces where they meet or at least on the little studs the pump sits between or something, although I'm sure that would've increased the cost. Oh, I have the unit sitting on a thick, soft, rubber mat too. It's not sitting directly on a hard surface that would exacerbate any vibration noise.

sorry, the one we have has not made any unusual sounds. Do you have pets? If yes, could it be hair around wheels? Or if its a motor bad sound, I'd consider returning the item. Sorry, best luck

First of all, I don't think my AC (indicated) is any louder than any other its size. Secondly, I think if is laying flat and supported and cushioned it won't rattle and vibrate any more than another would. Hope this helps. Mine is into 2nd year. For 8,000 BTU's it does a reasonable job - so far anyway.

i have one installed at 1000W@1ohm and it is incredibly loud without rattling my interior, and hits everywhere. the pressure is too much behind the ears sometimes. Adjusted the LPF filter to be lower and now I get all the vibration w none of the pressure in my head.

As long as your fan is clean, there really shouldn't be much noise under different load mods. I haven't heard that the fan is an issue.
