How long does split system installation take?
A standard split system installation typically takes between 3 to 6 hours, depending on the complexity (indoor/outdoor unit placement, electrical wiring, refrigerant piping). Most residential installations are completed within a single day. Our team works efficiently while ensuring high-quality workmanship and cleanliness.
For multi-split systems or large commercial projects, we’ll provide a clear timeline before starting.

We understand business needs: minimal disruption, fast turnaround, and energy-efficient solutions.
How often should I service my air conditioner?
We recommend servicing your air conditioning system at least once every 12 months. Regular maintenance helps:
- Prevent unexpected breakdowns

For commercial systems or units that run heavily, biannual servicing is often ideal. Airfrost offers scheduled maintenance plans across Sydney — contact us to set a reminder.
