The noise level of air conditioning units can vary. The loudest component is typically the compressor. Portable air conditioners can be quite loud, often reaching up to 55 dBA, because the compressor is housed in the indoor unit. However, modern split system air conditioners, which have the compressor located in the outdoor unit, are much quieter. This design helps minimize noise inside your home, ensuring a more peaceful and comfortable environment.
When the air conditioning units are run in heating mode, that is when they ramp up the pressures in the system, so this is when they are at their loudest. Many units in the Daikin range have a quiet mode for running units at night which is a fantastic feature
