Air Conditioning Melbourne: Find the Right System for Your Home

From evaporative cooling to ducted reverse cycle, Plum Trade Services supplies, installs, services and repairs every major air conditioning system across Melbourne and Geelong.

Evaporative Air Conditioning

Evaporative cooling is the most cost-effective way to cool your entire home, using up to 75% less energy than ducted refrigerated air conditioning while dropping temperatures by 8–12°C.

Running costs sit around $2–3 a day, and because it draws in filtered fresh air rather than recirculating it, evaporative cooling uses 80–90% less water than you'd expect and keeps indoor air quality high.

Every system comes with up to a 9-year unit warranty, plus Plum's lifetime workmanship warranty.

Not sure if it's right for you? Read our in-depth evaporative cooling guide.

Ducted Air Conditioning

Ducted reverse cycle air conditioning heats and cools your whole home from a single, near-invisible system, with zoning for up to 8 areas so you're only running the rooms you need.

Installation typically starts from around $10,000, with running costs of $5–10 a day (less if you're pairing with solar). VEU-approved units may be eligible for rebates of up to $5,000.

Every system is Wi-Fi controllable, and Plum is a registered warranty agent for both Brivis and Mitsubishi.

Split System Air Conditioning

Split systems are the most affordable way to heat and cool individual rooms, available in a range of colours and designs to suit any decor.

Small units (2.5–3.5kW) start from around $2,500 installed, while larger units (8–9kW) run from $3,650–$4,200 installed, with running costs of roughly $3–4 a day.

We install trusted brands including Mitsubishi Electric, Rinnai and Daikin, all backed by up to a 9-year unit warranty and Plum's lifetime workmanship warranty.

Getting the install right matters. Read our guide to perfect split system placement.

Multi Split Air Conditioner

A multi split system lets one outdoor condenser power up to 5 indoor units, saving on outdoor space while still giving every room independent reverse cycle heating and cooling.

A typical 2-bedroom setup runs from around $4,800–$5,200, while a whole-home system costs roughly $8,500–$12,500 installed. Every system is Wi-Fi app controllable.

We install Mitsubishi multi split systems and are a registered Mitsubishi warranty agent.

Add On Cooling

Already have Brivis gas ducted heating? Add On Cooling adds refrigerated cooling to your existing system, reusing your current ductwork and vents rather than starting from scratch.

Pricing starts from around $12,000, with near-silent operation and optional Wi-Fi control. Unlike evaporative cooling, it performs just as well on Melbourne's humid summer days.

Plum is a registered Brivis warranty agent for all Add On Cooling installations.
