Hello, due to the principle of operation, very large quantities of air must be sucked through the unit. For me as a "drilled-out craftsman", I can spend hours concentrating on programming work with it. For office sensibilities, I guess only the split units remain. The nerves with the noisy outdoor unit may be the neighbours. Milo offers 3 valve stages. And thus noise levels. LOW is usually enough for me. On AUTO on hot days
Full cooling capacity on hot days, with minimum possible noise levelx. During transitional periods, it can also be used for heating. Caution: The compressor causes a large starting current. A type C or D circuit breaker is recommended, otherwise the circuit breaker may trip. Yours sincerely, B.Peter
