Pre-filled for NCC zone 2 (Warm Humid, 145 W/m²). Covers Brisbane, Gold Coast, Sunshine Coast, Townsville. Enter your rooms for an instant cooling load estimate and ducted unit recommendation.
Zone 2 covers the warm, subtropical east coast. High summer humidity means evaporative cooling is ineffective — ducted reverse-cycle systems are the preferred solution. A 145 W/m² load factor accounts for Queensland solar angles and the latent load from moisture-laden outdoor air.
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.
