Looking for the quietest central air conditioner money can buy?
Then you need to look at an AC’s decibels (dB) rating, a unit used to measure the intensity of sound. The lower the decibel rating, the quieter the AC.
For example, on Carrier’s website you can see the quietest ACs by comparing their dB (sound) levels. The Infinity 19VS is quieter than the Infinity 21, as you can see from its lower dB level
Note: It says “as low as.” Which means it’s the lowest decibel level achieved from the quietest size within each model group during low fan-speed operation.
Currently, the 50-60 dB range is as quiet as an air conditioner can get. As of 2015, some of the quietest ACs include:
OK, so what do those numbers mean, though? How loud is 65 or 56 decibels? How will you know if the AC is quiet enough for you?
For a frame of reference, Purdue University’s Chemistry Department gives you examples of noise sources for each decibel level:
So, if you’re looking for a quiet AC, make sure it’s within 50 to 60 dB.
If you can’t find an AC’s sound level, look for certain features that imply quietness, including:
Remember that any sound rating you see implies two things:
In other words, the advertised sound (dB) is the AC running under perfect conditions.
So, if you have a larger home (implying a larger AC) and live in a hotter area like Florida (implying that the fan will run at a higher setting) the AC you buy will probably be louder than advertised.
You’ll need to get a professional AC installer to perform a Manual J Heat Load Calculation on your home.
Most reputable HVAC companies will do this for you free of charge as part of an air conditioner installation estimate.
Nice, right? You’re free to choose the first offer you get or leave it to find someone else with no charge to you.
