How makers measure noise

Makers do not measure noise the same way. TCL and Friedrich publish two figures, one with only the fan running and a higher one while cooling; Hisense lists its fan speeds; most Midea pages give one "as low as" figure without saying the mode. We rank on the cooling figure where there is one, and every number says which it is. No test program rates room-AC noise, so treat a few dBA as a tie.

What makes a window AC quiet

Two things. An inverter compressor slows down instead of switching on and off, so it hums instead of clunking. A U-shaped design puts the noisy compressor outside the window, with the window closing in the gap between the halves. Every 10 dBA is about twice as loud to the ear.

Size it first

Buy the size your room needs before you shop for quiet: a unit that is too small runs flat out, and that is its loudest. ENERGY STAR's sizing chart for an 8-foot ceiling. Add 10% for a very sunny room, take 10% off for a shaded one, add 600 BTU for each regular user over two, and 4,000 BTU for a kitchen. Bigger is not better: an oversized unit cools the room before it dries the air, so the room feels damp. The BTU calculator does the math for your room.

Questions buyers ask

What is the quietest window air conditioner?
On Amazon today, the Midea MAW06V1UBL: 32 dBA (the maker does not say which mode). Among units whose maker gives a cooling figure, the TCL H8W4KW is the quietest at 40 dBA while cooling.
Is a fan-only dBA figure the same as cooling?
No. With only the fan running, the compressor is off, so the unit is quieter than when it cools. TCL and Friedrich publish both, and their cooling figure is the higher one. Compare cooling with cooling.
Are U-shaped window ACs quieter?
Usually, because the compressor sits outside the window. Compare the published dBA figures and their mode, since they come from the makers, not a test lab.
