Four seasons
in a day.
One system.
Reverse-cycle moves heat instead of burning gas to make it — typically several units of heat for every unit of electricity, depending on conditions. Sized and zoned properly, it can replace your gas heating.
Most systems aren't underpowered. They're oversized, unzoned and never commissioned.
Comfort is a design problem before it's an equipment problem. We calculate the load room by room, zone it around how you actually live, and record the commissioning numbers.
Sized by the room, not the house
Glazing, orientation and insulation move the load by 40%. Square metres alone will always oversize the unit.
Ducted with no real zoning
A single dump zone means you heat the whole house to warm one room — the fastest way to a shocking winter bill.
Never commissioned properly
Unweighed charge and unbalanced airflow quietly cost you capacity for the life of the system, and void warranties.
Condition the rooms
you are actually in.
A typical three-bedroom Melbourne home, ducted with six zones. Tap a room to switch it on and watch the running cost move.
Filled rooms are being conditioned · everything else costs nothing to run
Only the rooms you selected are being conditioned. This is where zoning earns its money.
The same warm house,
two very different bills.
Drag the slider to match how long you actually heat for. Figures use current Victorian rates and identical comfort.

Five parts.
Comfort is in the design.

The compressor doing the actual work — sized, sited and quiet.
Sizing is a calculation,
not a rule of thumb.
Four inputs move the required capacity by more than 40%. This is the same maths we run room by room on site.
Fit the 4.5 kW unit and it short-cycles: it hits temperature, stops, dehumidifies poorly, and can cost more to run than the correctly sized one.
Six choices between
comfortable and expensive.
Every one of these is settled before the equipment is ordered.
Sized on heat load
An oversized unit short-cycles, dehumidifies poorly and costs more to run. We calculate, we don't estimate.
Written sizingZoned to how you live
Bedrooms at night, living areas by day. Conditioning empty rooms is where ducted systems get expensive.
4 – 8 zonesInverter, always
Variable-speed compressors hold temperature instead of hammering on and off — quieter and far cheaper.
Variable speedRuns on your solar
Pre-cool or pre-heat scheduled into the midday surplus window so the expensive hours start from comfortable.
Solar scheduledDuctwork actually sealed
Leaky, uninsulated ducting in a Melbourne roof space can waste a meaningful share of your capacity before it reaches a room.
R1.5+ sealedCommissioned and logged
Vacuum, weighed charge and per-zone airflow recorded, so warranty claims never turn into arguments.

equipment second.
You get the sizing sheet and the zone plan before you commit. If ducted isn't right for your house, we'll say so.
Home assessment
Room-by-room measurement of glazing, insulation, orientation and ceiling height for a proper heat-load figure.
Sizing sheet & options
Split and ducted priced side by side, with a zone plan and honest running-cost figures for each.
Installation
Mounting, refrigerant lines, sealed and insulated ductwork, zone motors and electrical — floors protected daily.
Commissioning & handover
Weighed charge, per-zone airflow balance and scheduling set for your solar window, with readings documented.
Split or ducted,
priced side by side.
The coverage bar shows how much of the house each option can condition at once — the honest way to compare them.
Single split
One living area or bedroom, no ductwork, one-day install.
Multi-head · 3 rooms
Per-room control without a ceiling full of ducting — heat only what you use.
Ducted · 6 zones
Whole-home comfort with constant-zone design, so it never dumps into empty rooms.
Illustrative examples only. Savings compare like-for-like comfort against ducted gas using example Victorian electricity and gas tariffs, and include the removed daily gas supply charge only where the home goes fully electric. VEU incentives may apply, subject to eligibility. Your fixed price follows the heat-load assessment.
Illustrative 6-zone ducted layoutVacuum, weighed refrigerant charge and per-zone airflow are measured and documented at handover — so performance is verifiable, not promised.
Comfort,
answered plainly.
Often, yes. A modern reverse-cycle system can deliver several units of heat per unit of electricity (a seasonal COP commonly in the 3–5 range, depending on conditions), so even on grid power it typically costs substantially less to run than ducted gas — and less again when it runs on your own solar.
Every part talks
to the others.
Solar, storage, charging, comfort and hot water are designed together — not bolted on one at a time.
