In India, we have been using "Ductless Air-Source Heat Pumps" aka split AC units with 3,4,5 star energy ratings for decades. The more efficient ones come with dual inverter compressor which allows them to operate at lesser power (for lesser cooling) during long continuous operation periods (like sleeping at night).

Having a heat pump warm up central heating water and use appropriate radiators or floor heating allows you to move the noisy bits outside the rooms you're in.
