Every split system on our best list is reverse cycle — in Australia there is no reason to buy cooling-only. But if heating is half the reason you are shopping, the ranking changes: what matters is how much heat a unit still delivers on a 2-degree morning, and how efficiently.
Reverse cycle is the cheapest heating most Australian homes can buy. A modern inverter delivers three to four units of heat per unit of electricity, which is why Victoria literally pays households to replace gas ducted heating with it.

Mitsubishi Electric's heating performance at low outdoor temperatures is the quiet reason it dominates Canberra and Melbourne quotes. Strong rated capacity down to freezing, sensible defrost behaviour, and the range covers everything from bedrooms to big living zones.
The same virtues that top our split list — near-silent operation, humidity control, dealer network — plus dependable heating output and comfort-focused airflow that does not blast your ankles at 6am.
MHI's premium series heats hard for the money and turns up constantly in trade conversations about value. If the quote gap to the big two is a few hundred dollars, this is where the smart money lands.
For replacing gas ducted heating outright, ActronAir's zoned reverse cycle systems are the Australian-engineered answer — per-room control, built for local extremes, and eligible for the big Victorian rebate when swapping out gas.
Street prices seen at major Australian retailers, August 2026, unit only unless stated — a standard back-to-back install adds roughly $700–$1,100. Your installer confirms the final figure on the invoice.
Heating load in a cold snap is usually bigger than cooling load in a heatwave, and capacity drops as the outdoor temperature falls. If winter comfort is the goal, tell the installer that — the right unit for Ballarat is not the right unit for Brisbane.
If you are running gas ducted heating in Victoria, do the rebate sums before winter. Between the Victorian Energy Upgrades discount and the running-cost gap, the payback on switching is the fastest in the country.

FAQ
For cold-climate heating, the Mitsubishi Electric MSZ-AP series leads on low-temperature performance; the Daikin Alira X is the best all-season unit; and Mitsubishi Heavy Industries is the value pick. For whole-home heating, zoned ducted from ActronAir or Daikin replaces gas properly.
At 2026 tariffs, usually yes. Reverse cycle delivers three to four units of heat per unit of electricity, and our running-cost calculator puts a typical living-room split at roughly 20–50 cents an hour of heating — under most gas ducted systems for the same warmth, before the Victorian rebate even enters it.
Yes. Modern units hold strong output well below zero, far colder than any Melbourne morning. The old reputation comes from undersized 1990s units — size it right and set 18–20°C, and it is the cheapest warmth in the house.
In Victoria, almost always worth pricing: the Victorian Energy Upgrades rebate can take $2,500–$5,530 off, and running costs drop for the same warmth. Elsewhere the maths still works more often than not — get the swap quoted before spending on a gas repair.
