Pre-filled for NCC zone 6 (Cool Temperate, 110 W/m²). Covers Melbourne, Hobart, Ballarat, Bendigo, Geelong, Launceston. Enter your rooms for an instant cooling load estimate and ducted unit recommendation.
Zone 6 has warm summers but cold winters. While the 110 W/m² cooling factor is lower, heating loads are significant — ensure your ducted system is rated for heating as well. Melbourne's notorious four-seasons-in-one-day weather also means systems cycle more frequently, making inverter technology important for efficiency.
Once you have your total L/s from this calculator, the next step is duct layout design. neuralduct auto-sizes every duct against AS 4254.2 velocity limits, validates the NCC J6 friction rate, and produces a compliant PDF for handover — all in the browser, free to try.
