What does heating and cooling actually cost to run?

A straight answer, by system type, home size, and how hard it runs — priced at current Mornington Peninsula rates, or your own. Built on Sustainability Victoria's published running-cost benchmarks, not a marketing estimate.

What this estimates

Pick a system, a home size, and how often it typically runs through the season, and the calculator gives a seasonal and annual running-cost range — never a single suspiciously precise number, because no honest estimate is ever exact. It also shows how that system compares to the other common options at the same settings.

What it assumes

Figures are scaled from Sustainability Victoria's own heating and cooling benchmarks for an average, pre-2005 Melbourne-climate home. Real running costs depend on insulation, glazing, ceiling height, draughts, occupancy, and the specific system installed — this tool is for comparing options, not replacing a proper site assessment.

Choose a system, home size, and how hard it typically runs. Electricity and gas rates are prefilled with current Mornington Peninsula defaults, but you can overwrite them with the rate on your own bill.

Estimated running cost

Reverse-cycle ducted

Whole-home electric heating and cooling through one ducted system.

Heating season$1,235-$1,730
Cooling season$115-$175
Estimated annual total$1,350-$1,905

Estimate for a medium (3-4 bed) home running reverse-cycle ducted at moderate (~8 hrs/day) use, priced at 27.4c/kWh electricity — scaled from Sustainability Victoria's home heating and cooling benchmarks for an average Melbourne-climate home.

How it compares

Estimated annual cost by system

Same medium (3-4 bed) home, same moderate (~8 hrs/day) use, same rates — just a different system.

Gas ducted$1,905-$2,420
RC ducted$1,350-$1,905
Multi-split$950-$1,270
Single split$295-$445
Portable heater$1,090-$1,330

Bars show the full efficiency range Hyde uses for each system (a basic model vs. a high-star-rated one) — not a margin of error. Ranges are estimates for comparison, not a quote: your actual bill depends on the specific system, the house, and how it's used. For a number to rely on, ask Hyde for a free on-site quote.

Methodology

How these estimates work

The seasonal dollar figures behind this calculator come directly from Sustainability Victoria's published heating and cooling running-cost benchmarks for an average existing Melbourne-climate home, across a range of system efficiencies (that's why every result is shown as a range, not one number). This tool then reprices those figures at the electricity and gas rates you enter — prefilled with the current Victorian Default Offer rate for the Mornington Peninsula's electricity network, and a representative current Victorian gas usage rate — and scales them by roughly how many hours a day the system runs in season. Reverse-cycle systems get their efficiency from a heat-pump COP typically in the order of 3-6 (energy.gov.au); gas ducted systems from typical burner input and AS4556 combustion efficiency; portable electric heaters are simple resistive elements, so all input power converts to heat.

Single split systems and portable heaters only condition one living zone, not the whole home, so their figures are scaled to a smaller area than a whole-home ducted or multi-split system — the calculator notes this whenever it applies.
