No, they are designed to operate at very low noise levels. Most models are as quiet or quieter than an equivalent electric unit.

Yes it is very safe. The gas is consumed outside the building. All gas installations are completed in accordance with the relevant Australian safety requirements.
No, the system only uses gas to drive an engine in the outdoor unit. The indoor units that provide the warm or cool air to the rooms are powered by electricity in the normal way.
