BUYING GUIDE

How Loud is Your Window Air Conditioner?

Before we move onto any of the more interesting stuff, we just want to make sure you understand how the noise level of an air conditioner is rated.

The level of noise air conditioners make is expressed in decibels (dB) – which is a unit of measurement that indicates how loud a sound is. Humans can hear sounds between 0 and 140 decibels. 0 decibel does not mean that there is no sound, merely that we cannot hear it. 0 decibel is the so-called hearing threshold for the human ear. Hearing more than 140 dB can be too painful for our ears. To buy a quiet window air conditioner, you need to look at an AC’s decibels rating. The lower the decibel rating, the quieter the AC.

To understand how loud is 60 dB or 50 dB? And, how will you know if the AC is quiet enough for you? Here we give you examples of noise sources for each decibel level:

  • A quiet conversation at home produces approximately 50 dB
  • A simple conversation between two people at a restaurant only marks 60 dB
  • Running a vacuum cleaner produces 70 to 75 dB.
  • Running a garbage disposal produces 80 to 85 dB.
  • Busy traffic comes it at 70 dB while a subway registers 90 dB and an airplane taking off comes in at 100 dB.

Here is the sound of an air conditioner

Here is the sound of a vacuum cleaner

As loudness increases, the amount of time you can hear the sound before damage occurs decreases. A noise level of 85 decibels within an 8-hour shift can lead to hearing loss. Those numbers above don’t really make sense. The difference between 50 dB and 60 dB is obviously 10 dB, but as far as decibels go it is around ten times louder. Also, 60 dB is 1/10 as loud as 70 dB.

Most window air conditioners on the market today rated from 40 dB to 70 dB. It’s inevitable that as an AC increases in size, noise levels will increase. A 10,000 Btu window air conditioner is often louder than an 8,000 Btu window air conditioner. An AC also generates more noise when it runs on higher fan speed. The quietest window air conditioners should be less than 60 dB on the lowest fan setting. And if your window air conditioner is rated less than 50 dB, it’s extremely quiet.

Air Conditioning Systems provide a “White Noise”

Although most people think that noise from air conditioners causes insomnia, it can have a positive affection on sleep as well. Sounds like white noise, for example, can moderate intermittent noise levels and provide a consistent backdrop for more peaceful rest.

Pediatric sleep consultant Jennifer Schindele suggests that environmental noise and new sounds can indeed disrupt sleep, however, she finds that white noise can help both kids and adults sleep well:

I often find that the addition of low to moderate level white noise can be very helpful to the sleep of my young clients. White noise works to block out normal everyday environmental noises that could cause a person of any age to startle awake or keep them awake in the middle of the night where solid and consistent sleep is needed the most.”

Choosing the Right Sized Window Air Conditioner

We need to clear up something crucial before we move onto looking at the quietest window air conditioners. After all, would you really spend money on something if it’s not capable of satisfying your needs, even if it doesn’t make a lot of noise? The best quiet window air conditioner must also be powerful enough to cool a room quickly and keep you comfortable. If an air conditioner can’t perform this function, then it does not serve its purpose.

Before looking at the noise level of a window AC, the first and most important consideration is the cooling capacity. For the best efficiency and effectiveness, stick with a unit that has a BTU level designed to fit your space. A window AC with too little BTU power will run continuously to try to cool a large space and, in the process, will eat up your energy budget. A window AC that’s too large for your space won’t cool and dehumidify your space evenly, leaving your room air susceptible to uncomfortable hot and cold pockets.

Window air conditioners typically have cooling capacities ranging from 5,000 to 12,500 Btu. For a small bedroom or home office (100 to 300 square feet), look for an air conditioner with a capacity of 5,000 to 6,000 Btu. To cool a bigger or busier room (250 to 400 square feet), you’ll want to step up to a mid-sized air conditioner rated at 7,000 to 8,500 Btu/hr. For a large room such as living room or family room (350 to 650 square feet), you’ll want a large air conditioner, 10,000 to 12,000 Btu/hr.

Other Things To Consider

Because the average household spends 15 percent of its annual utility bill on cooling, so it’s important to choose energy-efficient models. Look for a unit with an Energy Star label and an Energy Efficiency Ratio (EER) of 10 or above. An Energy Star qualified air conditioner use 15 to 20 percent less energy than units without that certification. And the higher the EER, the lower your operating costs. The best quiet window air conditioners have an EER of 10 or above.
