Is the equipment noisy in operation?
No. One of the most important design criteria for the equipment manufacturers, is a low operating noise level. Many systems incorporate ‘quiet’ or ‘silent’ modes, which provide sound levels as low as 20 dB(A) from the indoor unit and 43 dB(A) from the outdoor unit. In basic terms, you have to be within 2 metres of these units in the quietest of environments, to hear any indication that they are running.
