semiatic

Quiet / Silence

The indoor fan runs at its lowest, quietest speed, and on some makes the compressor is held back too, to cut noise.

What pressing it does

Panasonic’s QUIET “reduces airflow noise”; Daikin’s quiet airflow setting runs the fan at a weak level; Midea’s Silence (hold the fan button 2 seconds) also runs the compressor at low frequency. Samsung allows it in Cool or Heat and then fixes the fan speed.

What it does not do

It does not keep full cooling or heating power: Midea warns Silence may result in insufficient cooling and heating capacity, and Daikin says to change the airflow if the room does not reach the set temperature.

Makes differ, check your unit’s manual: the same drawing can mean different things on different brands, and only your model’s manual says exactly what a button does and which modes it works in.

What it looks like
Usually the word QUIET or SILENCE; some remotes use a fan with a single low bar or a figure with a finger to its lips. Our drawing is a speaker with one small wave.
Names makers use
QUIET (Panasonic, Fujitsu); Quiet (Samsung, Daikin airflow setting); Silence (Midea); Silent speed (Airwell)

Where makers differ

Most quiet settings act on the indoor fan. Daikin’s separate OUTDOOR UNIT QUIET and Mitsubishi Electric’s NIGHT MODE lower the outdoor unit’s noise instead.

Often confused with

A short burst at maximum fan speed and compressor output to reach the set temperature as fast as the unit can.
