Keystone air conditioners are also sold under the brand name "Polar Wind" at Meijer stores. I bought the 5,000 BTU Polar Wind unit about seven years ago and it has been a real little workhorse for me. I use it to cool down a fair sized open living room, dining and kitchen area. I just bought the 6,000 BTU Keystone unit for my master bedroom. I am surprised at how quiet it is.

Any compressor makes some noise. I can carry on a decent conversation with it right next to me; I also have no problem sleeping with the unit on. My pet rabbits are not bothered by it either.

I shared your skepticism back in my purchasing days. I can tell you this is a solid unit and it resides on the window of a 1.5 yr old baby......so far, it has never woken up our lil one. The compressor is pretty silent.

I never heard of them either. But it's a whole new world and I can't keep up:) As far as the noise - I obviously can hear it when it kicks in but I use the room a lot for phone calls and I never have a problem hearing over it nor do I find myself speaking louder. I'd say that after 30 seconds you don't even notice that it went into 'high drive'. Not a problem and I am sensitive to noise:)

I don't know about the brand but this has been a Great little machine! My hubby used in garage small work area during summer & was GREAT! Not noisy either. I had a non-star energy saver & noticed savings when we put this one in. Recommend highly!

I really have no idea. It is a generic switch that is pretty common to a lot of compressors.

none of them are particularly quiet in my experience with a usual rough vibratory tone made worse if they are operating under any back pressure. Run it free in a bucket and see how it sounds. If still loud then that's the sound of the pump.The maxijets are worse

Don't know because mine is not noisy. Maybe you should call the owner/manufacturer and ask. He is very helpful and nice to do business with.

It is a whole shop compressor so it is loud, but surprisingly quiet for this type of compressor... I have another 80 Gal in my shop that is louder!

It is a hard machine to quiet. I tried different ways of mounting it and still could not quiet it down. The unit I had had a compressor that was extremely loud when it would kick in or kick out.

There was one of these in the home I moved into last year. It worked well enough, but the vent fan sounded like a jet engine. Also, there seemed to be no noticeable sound difference between high and low. My model was made in 2006, so I'm not sure how much they've improved this since.

No, upon installation turned on the vehicle and the compressor was whisper quiet. A complete 180 from the previous compressor, which was as load as a jumbo jet. This new compressor works like a champ and is very quiet.

Hmm... I would say it's certainly quieter than a full size air compressor or a lawnmower, and I don't feel like I need to wear ear protection with it, but it does make some noise. My wife can hear it in our living room which is adjacent to the garage when I use it there. Hope this answer helps.

Many powerful pumps are noisy, just like small air compressors. The "smoke" is vaporized oil - it's normal.

Thank you! That was definitely part of my problem. One last question: when opening, I hear a pleasant ratcheting sound, which I don't hear when closing. Does yours also not make that sound in one direction?

Sounds like you may need a new unit. The first one that was delivered to us got very loud at the 6 month mark. Viva Appliances was awesome and exchanged us for a new one. The new one is super quiet....night and day difference from the first one.

I picked up factory reconditioned Bostitch compressor here on Amazon. It looked new out of the box and it's performed well. A little over hundred bucks.

The fan shuts off with the compressor. Bought this to replace a four year old unit from Lowes that ran continuously. This Keystone works great, I should have bought it a year ago. It dries the air quickly then cycles on & off as needed. Very quiet compared the old one.

If it is a Deni product it was made by Keystone Mfg. Co. in Buffalo, NY. They have been out of business for a few years now and Deni support phone numbers had a recording stating the same thing.

Have not had any problems with my unit. I do not like to keep air in the tank for any extended time due to condensation build up and possible rust inside the tank. My compressor is stored with drain valve open. It is the quietest compressor I have ever heard and has always worked for me. I have had the rolair for a little over a year now.

I run a 180psi viair onboard system and they are LOUD! My compressor cut back on once I'mdown to 110psi and they are still loud. Less than 110psi prob wouldn't be worth while
