Samsung measures 1 m in front and 1 m below
Each wall unit's sound pressure comes from an anechoic room, in cooling, with the microphone 1 m in front of and 1 m below the head; the outdoor drawing puts it 1 m in front of the unit at 1.5 m height. Both drawings sit in the "6. Sound Data" chapter of the RAC technical data book, whose notes say "Sound pressure level is obtained in an anechoic room" and that it "is a relative value, depending on the distance and acoustic environment."
Ceiling cassettes are measured differently. The cassette data book draws the 1-way's microphone 1 m to the side and 1 m below, and the Mini 4-Way's and 4-Way's 1.5 m straight below. Cassettes therefore meet only cassettes.
Two data books also print sound power, the total a unit radiates, "Measured according to ISO 3741". Power and pressure measure different things, so sound power gets a section of its own.
Samsung's 1 m is close to the distance Mitsubishi and Daikin draw. Microphone heights and test rooms still vary by maker, and comparing decibel ratings explains why a cross-brand gap of a dB or two means little.
Which Samsung mini-splits are current?
The R-32 systems. On November 6, 2026, samsunghvac.com listed the WindFree Standard, Premium, Max Heat and IAQ wall units, the 36K wall unit, and the light commercial 1-way, Mini 4-Way, 4-Way and 360 cassettes and floor console. The WindFree Premium page and its siblings offer 9,000 to 24,000 BTU single-zone sizes, plus a 7,000 BTU head "Compatible with FJM outdoor units only" that has no single-zone figure.
Max Heat is not a separate head. It pairs the Premium's indoor units, AR09DXDABWKNCV to AR24DXDABWKNCV, with the AR09DXDACWKXCV to AR24DXDACWKXCV outdoor units, so its indoor figures match the Premium's at every size.
Older R-410A WindFree model numbers, such as the AR09TSFABWKNCV, have gone from Samsung HVAC's product pages, and nothing here applies to them. A quote naming one calls for that unit's submittal from the contractor.
How quiet is a Samsung wall unit on Silent?
22 dB(A) at 9,000 and 12,000 BTU in every series, rising to 28 or 30 at 24,000 BTU and 38 on the 36K, all in cooling at 1 m.
| Size | dB(A) on Silent, cooling |
|---|
| 9,000 BTU | Standard, Premium, Max Heat and IAQ 22 |
| 12,000 BTU | Standard, Premium, Max Heat and IAQ 22 |
| 15,000 BTU | Premium and Max Heat 25; Standard and IAQ 27 |
| 18,000 BTU | Premium and Max Heat 25; Standard and IAQ 27 |
| 24,000 BTU | Premium and Max Heat 28; Standard and IAQ 30 |
| 33,000 BTU (36K) | 38, labeled Silence |
Below 24,000 BTU, the largest jump is the step from 22 to 25 or 27 between 12,000 and 15,000 BTU. A head sized no bigger than the room needs is the quiet choice, and the mini-split guide's bedroom section covers sizing across brands.
On High, the cheaper Standard leads at 18,000 and 24,000 BTU
High runs from 38 dB(A) at 9,000 BTU and 39 at 12,000 up to 51 on the 36K, in cooling, and the series order flips at the larger sizes.
| Size | dB(A) on High, cooling |
|---|
| 9,000 BTU | All four series 38 |
| 12,000 BTU | All four series 39 |
| 15,000 BTU | All four series 41 |
| 18,000 BTU | Standard and IAQ 41; Premium and Max Heat 42 |
| 24,000 BTU | Standard and IAQ 45; Premium and Max Heat 47 |
| 33,000 BTU (36K) | 51 |
The Premium wins on Silent, the Standard on High. A living room head often runs fast with people in the room, and the living room mini-split guide compares those larger sizes across makers.
The wall units' airflow rows list four speeds, "L/M/H/Turbo", and the Premium 09 submittal mentions "Three fan speed settings and auto settings". Noise figures cover only two of them, Silent and High.
The 36K breaks the pattern. Its data book prints four figures, "51 / 48 / 46 / 38" for "H/M/L/Silence", which puts its Low, 46, just 8 dB(A) above Silence and 5 below High.
A "Good'sleep mode" and a "Quiet mode" appear in the submittal's feature list too, with no separate figure for either in any document.
How quiet are Samsung's ceiling cassettes?
25 dB(A) at best, from the 1-way on Silent and the Mini 4-Way on Low, both at 9,000 BTU. Their microphones stood in different places, so each type is ranked only within itself.
| Cassette | Speeds and microphone | dB(A) |
|---|
| WindFree 1-Way AC009DN1DCG/AA | High / Mid / Low / Silent, 1 m to the side and 1 m below | "32 / 29 / 26 / 25" |
| WindFree 1-Way AC012DN1DCG/AA | Same | 35 / 32 / 29 / 28 |
| WindFree 1-Way AC018DN1DCG/AA | Same | 43 / 40 / 37 / 31 |
| WindFree Mini 4-Way AC009DNNDCG/AA | High / Mid / Low, 1.5 m below | 31 / 28 / 25 |
| WindFree Mini 4-Way AC012DNNDCG/AA | Same | 34 / 30 / 25 |
| WindFree Mini 4-Way AC018DNNDCG/AA | Same | 39 / 34 / 29 |
| 4-Way AC018DN4DCG/AA and AC024DN4DCG/AA | Low / Mid / High in the catalog, 1.5 m below by the data book | 30 / 33 / 36 |
| 4-Way AC030DN4DCG/AA | Same | 31 / 35 / 39 |
| 4-Way AC036DN4DCG/AA | Same | 32 / 38 / 43 |
| 4-Way AC048DN4DCG/AA | Same | 35 / 40 / 45 |
The 1-way and Mini 4-Way submittals print the same numbers under reversed labels, "L / M / H / Turbo" for the 1-way, so the order above follows the data book. The 1-way cassette page sells it in 9K, 12K and 18K sizes.
How loud is a Samsung outdoor unit?
For the wall systems, 45 to 54 dB(A) in cooling on High, 1 m in front of the unit, led by the 9,000 BTU units at 45. These figures describe what a patio or neighbor hears, and they are ranked only against each other.
| Size | Outdoor units | dB(A), cooling |
|---|
| 9,000 BTU | AR09DXDABWKXCV (Premium), AR09DXDACWKXCV (Max Heat), AR09DXFAMWKXCV (Standard and IAQ) | 45 |
| 12,000 BTU | AR12DXDABWKXCV, AR12DXDACWKXCV, AR12DXFAMWKXCV | 46 |
| 15,000 BTU | AR15DXDABWKXCV and AR15DXDACWKXCV; AR15DXFAMWKXCV | 48; 51 |
| 18,000 BTU | AR18DXDABWKXCV, AR18DXDACWKXCV, AR18DXFAMWKXCV | 51 |
| 24,000 BTU | AR24DXDABWKXCV, AR24DXDACWKXCV, AR24DXFAMWKXCV | 54 |
| 36K | AR36DXFUMGMXCV | 50 by its data book and the catalog |
The 36K's 50 would sit below the 24,000 BTU units, but its submittal prints 60, so it goes unranked. No WindFree submittal prints a heating figure; the 36K data book lists 52 in heating.
The cassettes' Premium outdoor units, AC009DXSCCG/AA to AC018DXSCCG/AA, list 46, 47 and 51 dB(A) in cooling in the cassette data book, also at 1 m and 1.5 m height. The July 2026 submittals for the 9,000 BTU cassette systems print 53 for the AC009DXSCCG/AA, though, and that keeps the cassette outdoor units out of the wall-system ranking.
Sound power, printed for the 36K and the cassettes
Measured to ISO 3741, Samsung's sound power figures run from 48 dB(A) on the Mini 4-Way AC009DNNDCG/AA to 69 on the 36K outdoor unit, and they are ranked only against each other.
| Side | Sound power, dB(A) |
|---|
| Indoor | Mini 4-Way 48, 51 and 56 (9K, 12K, 18K); 1-Way 52, 55 and 61; 36K 65 |
| Outdoor | AC009DXSCCG/AA 59; AC012DXSCCG/AA 61; AC018DXSCCG/AA 65; AR36DXFUMGMXCV 69 |
None of the WindFree wall-unit documents gives a sound power figure.
Where the documents disagree
Every WindFree wall figure matched across submittal, data book and catalog. Three outdoor figures and a console row did not, and where they differ this page follows the data book.
| Unit | Data book and catalog | Elsewhere |
|---|
| 36K outdoor | 50 cooling, 52 heating | "60 / 60" in the August 2026 submittal |
| AC009DXSCCG/AA | 46 and 47 | "53 / 53" in the July 2026 1-way and Mini 4-Way submittals |
| AC012DXSCCG/AA | 47 and 48 in the data book and the catalog's 1-way table | 54 and 54 in the catalog's Mini 4-Way table and that system's submittal |
| Console AC009DNJDCG/AA | The catalog's "L/M/H" row prints four values, "24 / 29 / 31 / 35" | |
The labels disagree too. The 36K and 1-way submittals call their four indoor figures "L / M / H / Turbo", lowest first, where the data books call the same numbers Silence or Silent to High. The numbers are identical either way, and this page uses the data book names.
Is WindFree mode quieter than normal cooling?
Samsung claims it is, on a basis that does not line up with its spec tables. The catalog says WindFree mode "produces only 26dB(A) of sound*" and charts 26 against 40 for "Normal mode" on the AR12DXDABWKNCV, and 29 against 43 on the AR24DXDABWKNCV. The same catalog's spec tables give those heads 22 and 39 on Silent and High, and 28 and 47. Its chart footnote calls the numbers "internal testing" and states no distance, so they stay out of every list.
For the 1-way cassette the catalog says "In WindFree™ mode, it produces just 24 dB(A) of sound*", charted for a "3.2kW model", a metric rating rather than a US model number. It is quoted here and not ranked.
What WindFree mode does is close the louver and push air through micro-holes in the front panel. The clicks and hums that no spec sheet captures are in the mini-split noises explainer.
Sold only through contractors
No price appears anywhere on samsunghvac.com. Its pages send buyers to a "Locate a Pro" contractor search and note "Product Registration Required. Conditions Apply." Every figure here comes from Samsung HVAC's submittals, data books and catalog, and Samsung warns that sound pressure "may differ depending on operation condition". Set 22 and 51 against everyday sounds on the decibel chart.
