Start with the controller
Check that the system is on the intended heating, cooling or fan setting. Confirm the target temperature and fan speed, and allow the system time to respond. Some operating modes change fan behaviour, so use the manufacturer’s instructions for the model rather than relying on another unit’s settings.
Look for visible obstructions
From a safe position, check whether curtains, furniture or other items are blocking the indoor unit’s intake or outlet. Outside, keep the surrounding area clear only where this can be done safely from ground level.
Do not climb, open equipment covers or place hands near electrical components or moving parts.
Follow the user instructions for accessible filters
Some systems have filters intended for routine user access. Follow the manufacturer’s instructions for the exact model. If the filter is difficult to reach, the instructions are unclear or access would require unsafe positioning, stop and request help.
Note what has changed
Useful details include when the airflow changed, whether the issue affects one mode or every mode, any new noise, leaking, repeated stopping or visible error code. A photo of the full indoor unit, outdoor unit and model label may help with the first conversation.
When to contact Airmax
If the simple checks do not resolve the problem—or the system shows another concerning symptom—contact Airmax with your suburb, make/model and what you have noticed. These details help identify the next sensible step; they do not replace professional fault-finding.
Use the Airmax contact page to send the details.
