What a air conditioning installation costs in Sydney
Sydney's humid summers rule out evaporative cooling and make reverse-cycle the default, for both the February heat and a little winter warmth. In the apartment-heavy inner city and east, the real cost driver is approval: mounting a condenser on a facade or balcony needs owners-corporation sign-off, there are rules on where it can go and how it looks, and limited external wall space can force a dearer multi-head solution.
In freestanding houses, ducted systems are popular but the install is dearer in two-storey homes and anything with a tight roof space. Sydney's high labour rates lift the fitting cost above the national figure, and peak-summer demand stretches lead times just when you want it done. A licensed electrician and a refrigerant-handling-licensed installer are both required, which is reflected in the quote.
