What a split system installation costs in Adelaide
Adelaide's lower labour rates make a standard split-system install one of the more affordable in the country, and the city's largely single-storey, accessible housing keeps most jobs to a simple back-to-back install with a short pipe run. For a conventional home, Adelaide is usually among the cheapest capitals to get one fitted.
The climate of hot, dry summers and genuinely cold winters means reverse-cycle units bought for both cooling and heating are the norm, so correct sizing for both duties matters. The city's older stone cottages and double-brick homes can add wall-penetration cost like Perth's, and an older house may need a switchboard upgrade, but for a standard home on an accessible block the combination of low labour and simple layouts keeps Adelaide at the affordable end.
