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.best central air conditioner ratings Using a level to see if it is right is necessary without assuming it is.mobile home hvac systems prices 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.air conditioner unit not window 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. While they are more affordable the compressor, fan, and other components will be louder than a well built unit. All window units will make some noise but some are quieter than others. This may not be a option if you are on a budget but if you need a new unit than here is a lit of units that make the least amount of noise. Window air conditioners are easy to install, setup, and cool a space at a much lower cost than having a HVAC company install a system.

Unfortunately since all the working parts are located in one package they will make more noise than other options. This doesn’t mean that they have to rattle about making so much noise as to make a living space uncomfortable. The above is just a few ideas to use.

Iconic One Theme | Don't Let Your Hard Work And Cool Air Go Out The Window As the temperature outside starts to heat up, you might be getting ready to install room air conditioners (AC) to cool your home. Before you do, read these tips from the New York State Energy Research and Development Authority (NYSERDA), so your hard work – and cool air – won’t go out the window. First, if you’re buying a new room AC, be sure to select an ENERGY STAR®-qualified model, which will save you more than $100 in energy costs over the lifetime of the unit. Installing your room AC unit correctly can save a bundle in energy costs, too.

In fact, in a report issued on April 14 by Urban Green (a chapter of the U.S. Green Building Council), researchers found that the average room air conditioner leaks as much air as a six-square-inch hole in the wall. Aptly titled There Are Holes in Our Walls, the report states that each poorly fitted and poorly sealed unit leaves a gap “about the size of your fist if you punched a hole in the wall.” NYSERDA recommends the following tips to keep the cool air in your house when using a room AC unit: Seal the unit’s top and bottom: Since most portable air conditioners are installed in an open window, the window must be lowered onto the top of the unit. Even if it looks like the window is tightly closed, there is usually a space between the unit and the window where air is leaking. Use a foam strip to insulate the gap where the two sashes meet. o   Home improvement stores sell kits to insulate your AC unit, which include foam rubber strips that squeeze into small spaces for a snug fit.o   Hardware stores sell foam insulation for pipes, usually in the plumbing section, which reduces “sweating” of the pipes in summer.

These are usually available in various lengths, but you’ll only need 3-4 ft. Be sure to buy the insulation for a 2-inch pipe, approximately the same size as the bottom edge of a window. Open the insulation where it is split and push it along the bottom of the window.Check the sides: When you expand the accordian-like sides on the AC unit, be sure they are not cracked or split, and that they fit snugly. Replacement units are available at most hardware stores.  Don’t forget the area between the upper and lower sash: Be sure to insert foam insulation in the space that is left when your window is open.  NYSERDA recommends these additional tips to maximize the operation of your window-type AC unit: Size it up: A properly sized air conditioner will operate more efficiently and dehumidify more effectively. Stir it up: Run ceiling paddle fans on medium, blowing down, in summer. Close it up: Close shades and drapes during the day to help keep heat out in summer. Clean it up: Remove and clean the AC air filter monthly. 

Seal it up: Keep “fresh air” vents closed on window AC units. When your air-conditioning unit is snug in its window, don’t neglect the other places in your home where cold air could escape. Use caulk to seal other windows and doors. DUE TO THE EXPECTED INCREASE IN ELECTRICITY DURING THE SUMMER MONTHS, PLEASE USE THE TIPS BELOW TO STAY COOL AND CONSERVE ENERGY: -Close blinds or shades on sunny windows, but open windows to take advantage of natural ventilation when conditions permit – especially during cool morning or evening hours. -Set the air-conditioning thermostat just a few degrees higher. Each degree above 75° F saves you 3 percent of the energy used to cool your home. -Turn off all lights and electrical appliances in unoccupied areas. -Run household appliances such as dishwasher and dryers at "off-peak" (after 7 p.m.) hours. These would include dishwashers, dryers, pool pumps and water heaters. -Keep doors closed when it is hotter outside than inside.
