What a split system installation costs in Melbourne
Melbourne's cold winters mean a split system is bought as much for heating as cooling, so reverse-cycle units sized to actually warm a room in a Melbourne July are the norm, and correct sizing matters more here than in the warm-climate cities. The period terraces and double-storey homes of the inner suburbs add access and pipe-run cost, while a single-storey home on a slab is a simple back-to-back install.
Melbourne has one of the deepest pools of air-conditioning installers in the country, so the market is genuinely competitive on standard single-head installs and prices sit around or below the national figure for a straightforward job. The cost climbs with a multi-head system to heat several rooms, with long pipe runs in a period home, and with any switchboard upgrade an older house needs to carry the load.
