What a split system installation costs in Sydney
The hardware is only part of a Sydney install — the labour and access decide the rest. Running pipe and drainage between an indoor head and an outdoor condenser is simple on a single-storey home, but on a two-storey terrace, across a tight side setback, or up to an apartment balcony it gets involved, and high-level or crane-assisted condenser placement lifts the cost well above a ground-floor job.
Apartments and townhouses bring strata approval and rules on where a condenser can go and how it looks, which adds time and sometimes dictates a dearer solution. Sydney's high electrical and trade labour rates lift the installed price above most capitals, so a simple back-to-back install in a single-storey home is affordable, while a high-access terrace or a strata-constrained apartment head is at the dearer end.
