Sure, a great boon but in the sixties most bungalows had ceiling fans in every room which provided most of the relief one needed. We lived in a hacienda type bungalow with louvred shutters and a patio open to the main living room which we locked at night by simply closing ornamental wrought iron gates leaving the air to flow through. I think we had folding glass doors too but these were rarely closed.
The only aircon room was my parents' bedroom.
With an ambient temperature of 30c most days and cooler nights I never recall as being as hot as I do here in Thailand.
After three years in Singapore I can remember my folks buying a portable heater for the living room when we all complained of the cold during a particularly cool winter monsoon!
Anyway, old Harry would say that since he was never comfortable in the heat and preferred the cold of England.
