How loud is a Bryant central air conditioner?
A Bryant central air conditioner rates 55 to 78 dBA of sound power on its product data sheet, depending on model, size and compressor speed. Every table ends with "Tested in compliance with AHRI 270 but not listed with AHRI"; only the 191VAN's names an edition, 270-2015.
Size codes are thousands of Btu per hour: 18 is 1.5 tons, 24 is 2, 36 is 3, 48 is 4 and 60 is 5. These are the rows Bryant prints.
- Evolution 191VAN, minimum and nominal cooling: 2 ton 55 and 68; 3 ton 55 and 72; 4 ton 64 and 72; 5 ton 58 and 72.
- Preferred 148TAN, low and high stage: 2 ton 67 and 69; 3 ton 68 and 69; 4 ton 71 and 71; 5 ton 70 and 73.
- Preferred 146SAN, single rating by size: 1.5 ton 70; 2 ton 67; 2.5 ton 69; 3 ton 67; 3.5 ton 73; 4 and 5 ton 74.
- Legacy 135SAN, without Sound Shield: 1.5 ton 72; 2 ton 73; 2.5 ton 71; 3 ton 69; 3.5 to 5 ton 75.
- Legacy 134SAN, without Sound Shield: 1.5 ton 72; 2 ton 74; 2.5 ton 72; 3 and 3.5 ton 74; 4 ton 78; 5 ton 74.
A minimum speed figure describes a variable speed unit idling. Compare it with another unit's low stage or minimum, and hold single stage ratings against nominal figures.
Which Bryant air conditioner is the quietest?
The Evolution 191VAN is the quietest Bryant air conditioner: its 2 and 3 ton sizes print "55" dBA at minimum cooling. No other Bryant AC prints a figure under 67, though the 191VAN's own 4 ton bottoms out at 64.
At full output the order flips. The 191VAN's nominal ratings are 68 to 72, while the single stage 146SAN rates 67 at 2 and 3 tons. On a 95°F afternoon, then, Bryant's sheets put the Preferred unit a point or more under the flagship.
What the 191VAN buys is time at the bottom of its range. A compressor that can throttle to 25% spends spring and autumn near 55 dBA, while a single stage unit has one speed and rates the same every time it starts. The same trade decides the quietest central air conditioners across brands.
Is the Bryant 148TAN 67 or 71 decibels?
The 148TAN is 67 dBA at its quietest, on low stage at 2 tons, according to Bryant's product data. Its product page gives both numbers: "Sound as low as 67 dB (quiet as a vacuum)" in the feature list, and "During most common cooling operating condition: 71 dB" in the specifications.
The category listing uses the 71, so a shopper filtering by sound sees the 148TAN rated four decibels worse than its sheet. In the table, 71 appears only at 4 tons, on both stages. The coastal 148TAN***C page repeats the same pair of figures.
Two stage units rarely run on high, which is why the low stage column matters more here. At 5 tons the low stage rates 70, under the 146SAN's 74 at that size.
How do Bryant's coastal air conditioners compare?
Bryant's coastal air conditioners carry the same sound claims as their standard versions: the 135SANC page says "as low as 71 dB" and the 148TANC page repeats its sibling's 67 and 71. Neither has its own sound table.
The C suffix marks a unit built for salt air corrosion, and the 148TAN sheet lists "C = Coastal" in its model number key. Asterisks on the product page stand in for the size digits. Nothing on Bryant's pages suggests the coastal build changes the noise.
What do Bryant's sound blanket and Sound Shield do?
Both wrap the compressor to cut its noise. The blanket is standard on the 191VAN, 148TAN and 146SAN; the Legacy Line gets an accessory cover that Bryant's tables credit with 0 to 3 dBA, depending on size.
The naming is loose. The 135SAN sheet calls the kit a "Sound Hood" in its accessory notes, the 134SAN a "Sound Blanket", the parts list a "SOUND BLKT KIT", and both rating tables say "with Accessory Sound Shield". Bryant recommends the cover for condensers placed "closer than 15 ft (4.57 m) to quiet areas, bedrooms, etc."
The gains are uneven. On the 134SAN, fitting it lowers the 1.5 ton by 2 dBA and the 3 ton by 3, yet the 2 ton reads 74 with or without it. On the 135SAN the 4 and 5 ton gain nothing at all.
How loud are Bryant heat pumps?
Bryant heat pumps rate 53 to 73 dBA of sound power across the five models with a data sheet table. The variable speed sheets list four figures per size: minimum and nominal cooling, then minimum and nominal heating. Nominal means "maximum speed operating at 95°F in cooling and 47°F in heating".
Two test editions appear. The 293VAN and 291VAN cite AHRI 270-2008, the 290VAN and 249VAN cite 270-2015, and the 248TAN names none, so we rank within each edition.
- Evolution Extreme 23 293VAN (2008 edition): 2 ton 53, 62, 54, 64; 3 ton 56, 64, 55, 68; 4 ton 56, 67, 56, 68; 5 ton 58, 72, 55, 71.
- Evolution Extreme 21 291VAN (2008 edition): 4.5 ton 58, 69, 55, 65.
- Evolution Extreme 290VAN (2015 edition): 2 ton 56, 68, 56, 71; 3 ton 55, 72, 54, 72; 4 ton 64, 72, 56, 73; 5 ton 58, 72, 55, 73.
- Preferred 249VAN (2015 edition): 2 ton 58, 67, 57, 67; 3 ton 59, 71, 59, 69; 4 ton 64, 71, 64, 70; 5 ton 61, 73, 62, 70.
- Preferred 248TAN, low and high stage: 2 ton 65 and 67; 3 ton 66 and 68; 4 ton 69 and 70; 5 ton 69 and 72.
Each set reads in the column order above. Our heat pump ranking across brands compares these with other makers.
Which Bryant heat pump is the quietest?
The Evolution Extreme 23 (293VAN) is the quietest Bryant heat pump, at 53 dBA minimum cooling in its 2 ton size under AHRI 270-2008. On the 2015 edition sheets, the 290VAN leads with 54 at 3 ton minimum heating and 55 at minimum cooling.
The 293VAN pulls further ahead at full speed. Its nominal cooling figures of 62 at 2 tons and 64 at 3 are lower than the 148TAN air conditioner's low stage, and lower than any other Bryant heat pump prints flat out at those sizes, though those sheets cite the 2015 edition or none.
Heating changes the order inside the 2015 group. The 249VAN's 2 ton rates 67 at nominal heating against the 290VAN's 71, so the cheaper Preferred unit is the quieter one on a cold morning at full output, despite a higher minimum.
Do Bryant's heat pump pages match the data sheets?
Only partly. The 293VAN and 248TAN pages match their sheets, but the 290VAN, 291VAN and 249VAN pages each print a figure as a cooling minimum that their tables put in the heating column, or nowhere.
- 290VAN: page "54 dB during lowest capacity cooling operating condition"; sheet minimum cooling 55, minimum heating 54.
- 291VAN: page 54 dB; sheet minimum cooling 58, minimum heating 55.
- 249VAN: page "During lowest capacity cooling operating condition: 57 dB"; sheet minimum cooling 58, minimum heating 57.
The 291VAN gap is the widest: four decibels between the page's cooling claim and the sheet's cooling row. The heat pump listing adds its own filter labels, "As low as 53 decibels" for the AeroQuiet System II tier. When a page and a PDF disagree, we go by the PDF, as our guide to comparing decibel ratings suggests.
Which current Bryant models print no sound table?
Two split heat pumps, the Preferred 246SAN and the Legacy 235SAN, show only page claims of "as low as 67 dB" and "as low as 70 dB", and we found no product data sheet for either. Floors like these are quoted on this page, never ranked.
The 235SAN's two claims disagree: its page says 70, while the heat pump listing files the Legacy line under "As low as 72 decibels". The coastal 235SAN***C page repeats the 70.
Three more heat pumps on the listing sit outside the ranking. The 37MUHA and 37MURA crossover units print outdoor sound pressure, "Levels as low as 59 dB(A)" and "Levels as low as 55 dB(A)", a different quantity from the AHRI 270 sound power above. The 33NM3 air-to-water system shows only "as low as 52".
Which Bryant air conditioners are discontinued?
Bryant's R-410A generation is gone from its US site: pages for the Evolution 189BNV, 186CNV and 187BNC air conditioners and the 288BNV and 286BNC heat pumps now redirect to the category listings. Every model ranked on this page uses Puron Advance, Bryant's name for R-454B.
A leftover remains. The air conditioner listing's sound filter still reads "Extremely Quiet AeroQuiet System II (dBA as low as 51)" and its Red Shield replacement warranty row still notes "Models 186CNV & 189BNV only", both from the older range. No current Bryant AC sheet prints a 51.
