Best Quiet Air Conditioners






Most air conditioners are in 60 decibel range, which is about the same volume as a conversation or light traffic. For comparison, a vacuum cleaner operates at around 75 decibels. Those who live in homes with central air are probably used to the loud hum and whir of an air conditioning unit. Since these units are outdoors, the loud noise they make is typically not an issue for homeowners.

However, portable air conditioners are inside the home, so while these units can help you beat the heat, the noise they produce can make your home uncomfortable. For instance, if you are used to sleeping in a quiet room, an air conditioner unit that is installed in your window will be a noticeable addition. If you are looking to keep noise in your home to a minimum, you will want to invest in the best quiet air conditioner.

Is Bigger Always Better?
Do bigger air conditioner units put out more air? Buying an air conditioner that is too large for a room means that it will cool off the space before it has had time to remove the humidity. This will leave your house or office musty and dank. Smaller, portable air conditioners don’t have this problem.
Are bigger air conditioners louder? One of the reasons to avoid extra large air conditioners is that they generate a lot of noise when in use. This can be distracting while you work during the day and detrimental to sleep. If you care about portability and noise, a mid-size to smaller-size air conditioning unit is recommended.
