Ducted air conditioning installation in Sydney typically takes one full day (8–10 hours) for a standard 3–4 zone residential system. The team arrives with all equipment, installs the indoor unit in the roof space, runs ductwork to each zone, mounts the outdoor condenser, connects the electrical supply, and commissions the system — all on the same day. Two-storey homes or installations requiring complex ductwork routing may take two days. Your installation team confirms the exact timeline at the free site inspection.
