Question: Our air conditioner was installed incorrectly by the builder 5 years ago. Is the repair of the resulting leak part of the strata maintenance responsibilities?
Answer: As it is likely not common property, you would need to repair it.
Generally speaking and without knowing where the external unit is located, an air-conditioning unit which services only one lot is that lot’s responsibility.
As for the defect in its original installation, as it is likely not common property, you would need to repair it.
