Which Central Air Conditioner is Quietest? A Kansas City Tech Answers
July 23, 2018
All central air conditioners have an audible ambient hum, but some models are inherently louder than others.
And nobody wants to be stuck with an AC that’s obnoxiously loud.
So, which air conditioner is quietest?
Well, any AC with a decibel range of 50 to 60 decibels (dB) is considered quiet.
In this article, we’ll cover the following info:

What are decibels?
Decibels (dB) measure the loudness of a particular sound.
The human ear can hear sounds as low as 0 dB, and sounds around 140 dB start to create painful ear damage (although, any prolonged exposure to sounds above 85 dB can start to cause ear damage).
Like we mentioned above, the quietest air conditioners fall within the 50–60 dB range.
To give some context, see the chart below to see what sounds correspond to certain dB levels:
AC systems that fall into the 50–60 db range
Some current quiet ACs on the market include:
American Standard AccuComfort™ Variable Speed Platinum 20 AC = as low as 54 dB
Lennox XC25 Variable-Speed Air Conditioner = as low as 59 dB
Carrier Infinity® 19 Variable-Speed AC = as low as 56 dB
Trane XV20i TruComfort™ Variable-Speed AC = as low as 57 dB
Note: You can find an air conditioner’s decibel level by looking at the marketing materials or technical specifications.
So, what makes one air conditioner quieter than another?
The quietest air conditioners come with noise-reduction technology, which includes:
Insulated base pan
Noise-reducing fan blades
You can verify if an air conditioner has noise-reduction technology by looking at brochures or online marketing materials (see screenshot below):
A note about decibel ratings...
When you see a decibel rating for an air conditioner, you need to know 2 things:
Bigger air conditioners are louder. Bigger air conditioners (measured in “tons”) are louder than smaller ACs by nature. So just be aware if you get a bigger AC, it will probably be louder than the dB level you see advertised.
Be aware that the advertised decibel rating is only true if the AC is running in optimal conditions. The advertised decibel rating is calculated while the AC is running in moderate weather and at the lowest motor speed, so the actual dB rating can fluctuate up to 10 dB.
