Tips for Your Air Conditioning in Victoria

Ducted systems cost 2–3x more than split systems but offer whole-house climate control with better aesthetics.

Choose a system sized correctly for your home — oversized units short-cycle (wasting energy) and undersized units run constantly.

Inverter systems use 30–50% less energy than non-inverter models and maintain more consistent temperatures.

In hot climates (QLD, NT, WA), prioritise cooling capacity; in cold climates (TAS, ACT, VIC), ensure adequate heating output.

Check your energy star rating — every additional star saves roughly 10% on running costs over the system's lifetime.

Frequently Asked Questions

How much does air conditioning cost in Melbourne in 2026?

Air conditioning installation in Melbourne ranges from $6k for a single split system to $19,000+ for a fully ducted whole-house system. The average mid-range ducted installation for a 3-bedroom home is around $11k.

Do I need a licence to install air conditioning in Victoria?

In Victoria, air conditioning installation requires both an electrical licence and an ARCtick refrigerant handling licence (issued by the Australian Refrigeration Council). Your installer should hold both. Verify credentials with VBA and the ARC register before engaging an installer.

What size air conditioning system do I need for my Melbourne home?

As a rough guide, you need 120–150 watts of cooling capacity per square metre of floor area. A 150sqm home in Melbourne typically needs a 15–20kW ducted system or 3–4 individual split systems. Get a professional load calculation rather than guessing — an incorrectly sized system wastes energy.

Is reverse-cycle heating effective in Victoria's cold winters?

Yes, reverse-cycle (heat pump) systems are the most energy-efficient heating option in Victoria's cool temperate climate, producing 3–6 units of heat per unit of electricity. They are far cheaper to run than gas ducted heating or electric bar heaters. Choose a model with a high COP (Coefficient of Performance) rating for heating.

What AC running costs should I expect in Melbourne?

In Melbourne, reverse-cycle AC is used for both heating and cooling, so annual running costs are typically $800–$1,500 for a ducted system in a 3-bedroom home. Good insulation (R4.0+ ceiling, R2.0+ walls) and double glazing significantly reduce these costs.
