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.
