In practical terms, most brands (if not all brands) in this capacity will not meet council requirements if noise is measured one metre from the outdoor unit. Council requirements are typically assessed at the property boundary (or the nearest noise-sensitive receiver), so the noise level at the assessment location may be lower than what is stated at close range—however this should be confirmed against the specific council methodology and site layout.
It is also important to note that compliance is highly dependent on the installation environment. If the outdoor unit is installed in an area with hard surfaces (e.g., concrete walls/floors, narrow passages, alcoves or corners), sound can reflect and amplify, which may increase the measured result.
At this stage, we do not have a specific product or accessory we can supply that will reliably reduce noise to meet a council condition. If an acoustic barrier or screening solution is pursued, it must be designed so the unit can maintain required airflow and service clearances. Any solution must allow the unit to “breathe” and be installed strictly in accordance with the installation manual—restricting airflow or enclosing the unit can impact performance and reliability and may lead to faults.
Recommended next steps:
Confirm the council assessment point and measurement method (boundary/receiver location and any adjustments applied).
Review outdoor unit placement to maximise separation from boundaries/bedroom windows and avoid corners/alcoves where reflections can increase sound.
Consider re-orientation or relocation so discharge is directed away from the most sensitive boundary/receiver.
Ensure anti-vibration measures and mounting are appropriate to minimise structure-borne noise.
If screening is required, engage an acoustic consultant to specify a compliant barrier/screen that does not compromise airflow or access.
If you can provide the proposed outdoor unit location (site plan/elevations) and confirm the council measurement position, we can provide guidance on placement/clearances and any available acoustic documentation to support your response.
