A cool refuge from a heat that no longer behaves.
British summers aren't what they used to be. Done well, air conditioning is the quietest, most efficient way to make a home liveable in 30°C; without a portable unit roaring at the foot of your bed.
A modern inverter split is a different machine to the rattling boxes most people imagine. The right unit, correctly sized for the room, runs at the volume of a quiet library and costs pennies a day to operate. Most of what makes AC noisy, ugly or expensive is bad sizing and bad installation; both solvable.
