What is a normal or good noise level for an AC?

Across our catalogue, real models range from 27dB (whisper-quiet) to 38dB (still reasonably quiet, comparable to a library). Anything above the high-30s starts to become noticeable in a quiet room. If your AC is meaningfully louder than that, it's worth checking installation and servicing rather than assuming that's just how it sounds.

📐 Calculated estimate Based on real BEE-certified data — see the exact numbers below.

For reference, 27-30dB is close to the sound of rustling leaves, while 35-38dB is closer to a quiet conversation at a distance — genuinely unobtrusive for most rooms. If an AC is producing noise well beyond its rated dB — grinding, rattling, or a loud hum — that's a sign of a real problem, not just "a slightly louder model."
