Mitsubishi Heavy Industries Air Conditioning Sydney
Japanese heavy-engineering pedigree — exceptionally quiet, compact, and built to outlast Sydney's harshest summers.
About Mitsubishi Heavy Industries
Mitsubishi Heavy Industries (MHI) is a separate company from Mitsubishi Electric, with its own century-long heritage in precision heavy engineering — the same discipline that builds turbines, aircraft and industrial machinery now goes into its air conditioning. In Australia, MHI has built a loyal following among installers who value the brand's robust build quality, ultra-compact outdoor units, and class-leading quiet operation.
The flagship Bronte (SRK-ZSA) and Avanti Plus (SRK-ZRA) hi-wall ranges run on eco-friendly R32 refrigerant and pair a high-efficiency inverter compressor with one of the smallest outdoor footprints on the market — a genuine advantage for Sydney's terrace homes, balconies and tight side-access installs. MHI units are also among the quietest available, with indoor sound levels starting at just 19 dB(A), and back qualifying models with a 5-year parts and labour warranty.

+61 429 401 541No — they are two entirely separate companies that both trace back to the historic Mitsubishi group but operate independently today. Mitsubishi Heavy Industries (MHI) and Mitsubishi Electric each design and manufacture their own air conditioning ranges. Both are excellent; MHI is particularly known for very quiet operation and compact outdoor units, which makes it a strong choice for apartments and homes with limited outdoor space.
The Bronte (SRK-ZSA) is MHI's premium hi-wall series, offering the highest efficiency, the quietest operation, and the most advanced air-filtration and control features. The Avanti Plus (SRK-ZRA) is the mid-tier series — it shares MHI's compact design and R32 inverter technology at a more accessible price point. We'll recommend the right series for your room size and budget during your free site inspection.
Yes — MHI is one of the best choices for Sydney apartments. The outdoor units are among the most compact available, which helps satisfy strata body-corporate requirements and suits balcony installation. Indoor units are exceptionally quiet, making them ideal for bedrooms. We handle all strata approval documentation as part of the installation.
MHI's residential hi-wall range runs from 2.0 kW (suited to a small 10–15 m² bedroom) up to 7.1 kW (for open-plan living areas up to around 60 m²), plus multi-split and ducted configurations for whole-home solutions. We carry out a load calculation during your free site assessment to specify the correct capacity for each room.
A hi-wall split system typically takes 3–5 hours. Multi-zone systems and ducted whole-home installations generally require a full day or, for larger properties, two days. We confirm a detailed timeline when booking and keep disruption to a minimum.
