Having a quiet window mounted air conditioner can go a long way in creating a comfortable living space. The noise a window unit makes does vary between manufactures but there is somethings you can do to help get rid of unwanted noise. Here are some of the things I have found over the years to help quiet a unit. If you have any tips let us know in the comments below. The sides of every window unit never fits exactly into the space leaving a gap on the sides. Most every manufacture will give a slider to fill the gap which is thin and does a less than desirable job. Using foam insulation on the sides is much better at muffling the noise and also helps in keeping the cols air inside. It will depend on how big the gap is as to how much installation to get. I have found pipe insulation works good for small gaps. There is side insulation packages that can be bought and cut to fit a install which likely is a better solution.

While the window is likley level for the most part, even small bumps can throw a unit off. Using a level to see if it is right is necessary without assuming it is. The components in a package are all setup to work when it is flat, so even if it is slightly off vibrations will happen which will than make noise. I seen this at a friends home which does help keep the sound levels down. Don’t hang a blanket directly in front of the unit but away 4-5 feet with the sides open. As long as the room is big enough and you are situated on the other side, the room will still be cooled and the noise level will go down. Not every one will be able to do this, especially if you have small a room, but for large spaces it can help. Sometimes the cage will rattle at certain locations.

Using something like a small piece of insulation pushed between the cage and the window will stop it from vibrating. It may seem simple but it does work and something I have used in the past to stop a rattling sound.Buy a Better Unit Some units are made cheaply and mass produced quickly.

Identifying Quiet Window Air Conditioners Is No Easy Task Noise is one of the most common reasons for dissatisfaction with a window air conditioner (A/C). Most people would prefer a but when you're shopping for one, it's not easy to tell how noisy a given model will be. One reason is that noise measurements (decibel readings) are rarely included in manufacturers' product literature.

Another problem is that you often don't get the chance to hear an installed unit in operation before buying it. Types of Air Conditioner Noise To further complicate matters, there are different kinds of noise that an air conditioner might make: The hum of the fan under ordinary operation Rattling and vibration of the case or internal parts A thunking sound made by the compressor when it switches on Electronic beeping sounds when you adjust the controls Shaking and rattling of the glass or frame in the window where the unit is installed Noise from outdoors that is no longer being blocked, since the window is no longer shut If a model gets good ratings in independent side-by-side testing for low fan noise, that won't mean much to you if the thunk of the compressor kicking in wakes you up at night. Another example is a model that gets very good reviews for quiet operation as well as for overall quality and value, but which makes a piercingly loud beep every time a control is adjusted, a detail which makes it an unacceptable choice for many consumers.

Some rattling and vibration sounds are created or made much worse if a unit is not installed properly. For quietest air conditioner operation, it is essential that the unit be installed according to the manufacturer's instructions.

If quiet operation is a very important factor for you, you may want to consider a instead of a window A/C unit. These are nearly noiseless, much quieter than any window unit you can buy. Tips for Reducing Noise in Your Existing A/C Window Unit If you have a window air conditioning unit and you're not in the market to buy a new one, here are some things you can do to minimize the noise it makes: First, verify that the original installation procedures have been followed properly. Pay special attention to any gaskets. If improperly installed, even a high quality, low-noise unit can rattle mercilessly.

For noise originating from inside the unit: Be sure that all the compressor mounting parts are present and are properly tightened. If you identify a part that is rattling against another part, you might be able to eliminate the noise by slightly repositioning it. For vibration noise in the A/C case or the window: Be sure all the mounting screws are present and are tightened properly. If the window frame is vibrating, fill the gap with wooden shims or with foam weatherstripping applied to the A/C frame where it meets the window frame. If the glass panes in the window are rattling, apply window putty to secure the glass panels. Keep the fan blades clean. Dirt on the blades can cause them to become out of balance, prematurely wearing out the bearings. Recognize that new units are quieter than older units, especially compressors. In some cases, with an aging appliance, replacement of the entire unit may be the best option to reduce the noise. Read more: Recommended brands and models of quiet air conditioners for windows
