Mitsubishi Heavy Industries — The Ranges We Stock

MHI has been engineering HVAC equipment for over 130 years. Their Australian range is purpose-designed for local conditions — strong reverse cycle heating and cooling performance across a wide range of climates. All ranges below use R32 refrigerant and carry a 5-year parts and labour warranty.

Avanti Series

MHI's entry-level wall-mounted split — and one of the highest-rated split systems on ProductReview Australia. The Avanti is suited to small and medium spaces and includes Clean Air Technology to capture allergens, smoke particles, odours, bacteria and viruses. Reliable, straightforward and popular with tradies for residential installs. Available in reverse cycle and cooling-only configurations.

Avanti Plus Series

A step up from the standard Avanti, the Avanti Plus Platinum Series adds enhanced performance specs and the NOVAShield PM2.5 filter for improved air quality. Built-in Wi-Fi on WF1 models means no optional adaptors needed — Google and Alexa voice control is ready to go straight out of the box. A strong option when the customer wants smart home integration without the fuss.

Bronte Series

MHI's premium wall-mounted split for larger spaces. The Bronte includes Jet Air technology for faster room conditioning — useful in large living areas where the customer wants to feel the difference quickly. Available at higher capacities than the Avanti range, making it the right call when you're covering a larger floor area and need the extra grunt. Available with built-in Wi-Fi on WF1 models.

Ciara Series

The Ciara is MHI's design-focused series — a sleek, premium-looking unit for spaces where aesthetics matter as much as performance. Think architect-designed homes, high-end apartments and commercial fitouts where the client doesn't want to look at a standard white box on the wall. Performance specs are strong across the range with all the features you'd expect from a premium MHI product.

Fujitsu General — The Ranges We Stock

Fujitsu General (also known as General Airstage in Australia) is consistently rated as one of the most installer-friendly brands in the market. Tradies who work with both brands regularly comment that Fujitsu units are clean to install, reliable long-term and generate minimal callbacks. Both ranges use R32 and carry a 5-year parts and labour warranty.

Lifestyle Range

Fujitsu's flagship residential wall-mounted split. The Lifestyle range is designed to blend into modern interiors — slim profile, matte finish, clean lines. The standout feature is Human Sensor Control, which detects room occupancy and automatically shifts to energy-saving mode when no movement is detected for 20 minutes, reverting to normal settings when someone returns. For rental properties and offices this is a genuinely useful feature that reduces running costs without any input from the end user. Economy mode and weekly timers add further flexibility. Some models reach a 5-star energy rating.

Comfort Range

Fujitsu's entry-level wall-mounted split — a solid, no-fuss reverse cycle unit that does exactly what it's meant to do. The Comfort range is the right call when the job is straightforward and the customer doesn't need the additional features of the Lifestyle range. Reliable, competitively priced and backed by the same 5-year warranty. Popular for standard residential installs, rental properties and small commercial spaces where budget is a consideration.

Which One Should You Recommend?

You can't go wrong with either brand. The decision usually comes down to the specific job and what the customer values most.

The customer wants smart home integration out of the box
→ MHI Avanti Plus or Bronte (WF1 models). Built-in Wi-Fi and Google/Alexa voice control without needing to purchase an optional adaptor separately.
It's a rental property or the customer wants automatic energy saving
→ Fujitsu Lifestyle. Human Sensor Control automatically reduces energy use when rooms are unoccupied — no user input needed. Ideal for tenants who leave things running.
Aesthetics are a priority — architect-designed home or high-end fitout
→ MHI Ciara. Designed specifically for spaces where the unit needs to look the part, not just perform. A premium aesthetic without compromising on specs.
It's a straightforward residential install and budget matters
→ Fujitsu Comfort or MHI Avanti. Both are reliable, competitively priced entry-level options backed by the same 5-year warranty as the premium ranges. No corners cut on quality.
It's a large space and the customer wants fast, powerful conditioning
→ MHI Bronte. Jet Air technology gets large rooms up to temperature faster. The right call for bigger living areas where performance is the priority.
Cold climate install — Melbourne, regional VIC, Tasmania
→ Check the heating specs on the specific model. Both brands perform well in reverse cycle heating but always check the rated heating capacity at low ambient temperatures before specifying in cold climates. MHI has a strong reputation for cold climate performance across the range.

Common Questions

Are Mitsubishi Heavy Industries and Mitsubishi Electric the same brand?
No — they are separate companies. Both are part of the broader Mitsubishi group but operate independently with different product ranges and distribution networks. Fastflex stocks Mitsubishi Heavy Industries (MHI). If a customer asks for "Mitsubishi" make sure you clarify which one they mean.
Is Fujitsu General the same as General Airstage?
Yes — Fujitsu General rebranded its Australian residential operations to General Airstage. Same products, same warranties, same support network — just a different name on the documentation.
What warranty do both brands offer?
Both MHI and Fujitsu General offer a 5-year parts and labour warranty on domestic systems installed in Australia, provided installation is carried out by a licensed installer in accordance with the manufacturer's installation manual and warranty card requirements.
Do I need an ARCtick licence to purchase these units from Fastflex?
Yes — as both brands use R32 refrigerant, purchasing requires a valid ARCtick RTA (business) licence. Installation must be carried out by an ARCtick-licensed technician to maintain the manufacturer's warranty.
