AnomalyConstant, lowvfrequency sound, similar noise to a tank water pump or a small transformer rigged to one house such as a rural electricity supply to a property. I've looked around the neighbourhood and listened for possible causes. New transformers on street poles, other reverse cycle airconditioners or pumps running. Have managed to find two water leaks re: mains pressure changes: Yet to be fixed. Turned off the mains electricity - no luck. Turning off the mains water is slightly more difficult but shall be done to see if it could be responisible.
