Is Fujitsu or Mitsubishi Heavy Industries better for ducted AC in Sydney?

Both are Japanese-engineered mid-range brands at similar prices (Fujitsu from $9,800, MHI from $9,900). Fujitsu's standout advantage is its 310mm slim indoor unit for homes with limited roof clearance. MHI has a reputation for compressor longevity from its industrial heritage. For standard residential installations, both perform similarly — the choice often comes down to roof space (Fujitsu for tight spaces) vs long-term durability preference (MHI).

What is the price difference between Fujitsu and MHI?

Fujitsu starts from $9,800 and MHI from $9,900 — a marginal $100 difference at entry level. For a comparable 14kW 5-zone system, both typically land within $300 of each other. Neither brand carries a significant price premium over the other in Sydney's market. The decision is better made on features (slim unit vs industrial build quality) than on price.

Which is quieter — Fujitsu or MHI?

Fujitsu is quieter at 25dB indoor vs MHI at 22–26dB depending on model. Both achieve acceptable noise levels for residential use. For bedroom-adjacent placement of the indoor unit or return air grille, Fujitsu's quieter specification is a meaningful advantage. MHI's outdoor units are generally very quiet and typically meet Sydney's residential noise limits with ease.
