Company Background & Australian Presence

Mitsubishi Electric is one of the world’s oldest and most recognised air-conditioning manufacturers, originating in Japan in 1921 and expanding globally throughout the mid-20th century. The company produces a wide range of residential, commercial and industrial HVAC equipment and is known for its long-term focus on reliability, quiet operation and advanced inverter technology. Mitsubishi Electric entered the Australian market more than 50 years ago and has since established a strong local footprint across every state and territory.

A common point of confusion is the difference between Mitsubishi Electric and Mitsubishi Heavy Industries. While they share historical origins and the Mitsubishi name, they are entirely separate companies, each operating independently with their own product lines, engineering teams and Australian distribution networks.

In Australia, Mitsubishi Electric operates through Mitsubishi Electric Australia Pty Ltd, headquartered in Rydalmere, NSW. The brand maintains local warehousing, spare parts facilities, authorised service partners and technical support centres nationwide. This strong on-the-ground presence helps ensure reliable warranty support from a trusted Australian presence, and contributes to the brand’s reputation for long-term product reliability among installers and homeowners. With a broad range of split systems, multi-splits and ducted products, Mitsubishi Electric is well-established as a premium, trusted choice for Australian households.

Air Conditioner Range, Efficiency & Performance

Mitsubishi Electric’s residential lineup covers a wide range of Australian households, from premium buyers to budget-conscious renovators. Manufactured in Thailand, the MSZ-LN Series suits customers seeking top-end comfort features, ultra-quiet operation and premium finishes. The MSZ-EF Series appeals to design-focused homeowners who want a slimmer, more stylish indoor unit without stepping up to the LN’s price point. The MSZ-AP Series is the most versatile and best-value option, offering strong efficiency and reliable performance for the majority of small to medium rooms.

For very large open areas, the MSZ-AS90 provides high-capacity heating and cooling at a competitive price. Mitsubishi Electric also offers floor consoles, bulkheads, cassettes, multi-split systems and ducted solutions for homes with limited wall space or whole-of-home conditioning needs.

MSZ-LN Series (Premium Range)

The LN Series is Mitsubishi Electric’s top-tier wall-mounted split system, featuring premium finishes, ultra-quiet operation and several comfort and hygiene features. Features include it’s 3D i-see Sensor that scans the room and adjusts airflow automatically, the Plasma Quad Plus that acts like an air purifier, reducing dust, allergens, and bacteria, and Dual Barrier Coating that helps stop dust and oil from sticking inside the unit. This series sits at the premium end of the market and competes with the highest-spec models from Daikin and Fujitsu.

* Star ratings from the Australian Government Energy Rating Register and show efficiency under test conditions — higher stars mean lower running costs.

MSZ-EF Series (Designer Range)

The EF Series combines a slimmer, minimalist aesthetic with colour options (white, silver, black). Efficiency is solid across small-to-medium sizes, though lower than the LN Series. It competes with Daikin Zena and Panasonic Z-Series on styling.

* Star ratings from the Australian Government Energy Rating Register.

MSZ-AP Series (Core Range)

This is Mitsubishi Electric’s most popular range, balancing affordability, performance and quiet operation. Efficiency is excellent in small systems, especially the AP25, with up to 6-star cooling ratings. This range competes directly with Daikin Alira X and Fujitsu Lifestyle models.

* Star ratings from the Australian Government Energy Rating Register.

MSZ-AS90 (Large 9.0 kW Split System)

The AS90 is Mitsubishi Electric’s largest wall-mounted split, intended for open-plan living areas. Efficiency drops as expected for high-capacity units, but airflow, noise levels and reliability remain competitive.

* Star ratings from the Australian Government Energy Rating Register.

Other Residential Split Systems

These include floor-mounted, ceiling cassette and bulkhead units for homes with limited wall space or renovation constraints.

• MFZ-KW Floor Console — compact, fits into fireplace cavities; quiet operation; suited for heating-focused households.
• SLZ-M Ceiling Cassette — 4-way airflow; suited for rooms without usable wall space.
• MLZ-KP Slim Cassette — 185 mm installation height; ideal for low ceilings.
• SEZ-M Bulkhead — concealed, ducted-style appearance for modern homes.

Efficiency is generally lower than Mitsubishi Electric’s wall-mounted ranges, which is typical for these system types.

Multi-Split Systems

Mitsubishi Electric’s multi-split range supports up to 8 indoor units connected to a single outdoor unit. Indoor units from the LN, EF, AP and floor-console ranges can be mixed. Multi-splits suit homes where outdoor space is limited, but efficiency is usually lower than individual split systems due to shared compressor loads.

Typical applications include:

• apartments with balcony restrictions
• homes requiring multiple small rooms conditioned
• designs prioritising a single outdoor footprint

Ducted / Whole-of-Home Systems

Mitsubishi Electric also offers a full ducted range (PEAD, PEA and other series) with zoning options. Key features include:

• slimline units for tight ceiling spaces
• broad capacity options suited to both single-storey and double-storey homes
• optional Wi-Fi and advanced controllers
• efficient inverter compressors

Pricing depends heavily on home size, duct design and zoning. Mitsubishi Electric ducted systems compete closely with Daikin and Toshiba in this segment.

Cost of Mitsubishi Electric Air Conditioners

Mitsubishi Electric sits between mid-range and premium pricing in the Australian market, varying by series. Typical supply-only costs for single split systems (not including installation) are:

• MSZ-AP Series (core range): $1,050–$2,200 depending on capacity
• MSZ-EF (designer range): $1,800–$3,200
• MSZ-LN (premium range): $2,600–$4,000
• MSZ-AS90 (large capacity): ~$3,800–$4,800

Installation costs vary depending on pipe runs, double-storey access, switchboard suitability and wall penetrations. Homeowners should also consider accredited installers for correct sizing, placement and commissioning.

These estimates exclude rebates you might be available for through state schemes like the NSW Energy Savings Scheme, VIC Energy Upgrade discount and SA Reps Scheme.

How Does Mitsubishi Electric’s Warranty Stack Up?

Mitsubishi Electric provides a 5-year parts and labour warranty on all residential split systems, covering both the indoor and outdoor units when installed by a licensed installer. The warranty is clear, consistent and easy to interpret, and aligns with leading brands in Australia.

Product Warranty

Coverage includes manufacturing defects for five years from the installation date, provided the system is installed within 12 months of purchase and used for residential climate control. Replacement parts installed under warranty are covered for the longer of 12 months or the remainder of the original warranty period.

What the Warranty Covers

• Parts and labour for legitimate manufacturing defects
• Attendance by an authorised repairer within 50 km of their base
• Repair or replacement at Mitsubishi Electric’s discretion
• Coverage applies only to units purchased in Australia from authorised retailers and installed by licensed installers

All the regular exclusions for improper use and installation are included in the warranty. There shouldn’t be a need to worry about this as long as you get the product installed by an accredited and reputable installer.

Consumer Takeaway

The Mitsubishi Electric warranty is strong, transparent and consistent with top-tier brands. Its nationwide parts availability and after-sales network make real-world warranty outcomes reliable, though consumers should be aware of access-charge exclusions, especially for multi-storey installations.
