What a air conditioning installation costs in Melbourne
Reverse-cycle dominates here because it does double duty: Melbourne's cold winters mean the system is sized for a real heating load, not just a few hot days, which pushes buyers toward higher-capacity units than a warm-climate home needs. The city's Victorian and Edwardian housing is the complication, with no ducting cavities, plaster ceilings and heritage constraints that make a ducted retrofit involved and often tip owners toward multiple split systems.
The deep local trade pool keeps competitive pressure on planned installs, so a few quotes genuinely pays off. Dry northerly days still make evaporative cooling a cheaper-to-run option some homes choose, though it does nothing for heating. A licensed electrician and a refrigerant-handling licence are required, and winter is actually a good time to buy, when demand and lead times ease.
