A standard single split system installation in Australia typically takes between three and six hours for a straightforward back-to-back setup, where the indoor and outdoor units sit on opposite sides of the same wall.
More involved jobs, such as those requiring a longer pipe run, double brick walls, second-storey access, roof-mounted outdoor units, or switchboard upgrades, can take a full day or longer.
Multi-split systems connecting several indoor units generally require one to two days. If you live in a strata property, strata approval may add time before work even begins. Getting a quote that includes a site inspection beforehand will give you the most accurate timeframe.
Blue Mountains Air offers upfront quotes with a full site assessment so you know exactly what to expect before any work begins.
