Weighing Up The Design & Install of Mitsubishi vs Fujitsu

As we dive deeper into their rivalry, let’s explore the fascinating realm of design and installation, where choices abound and aesthetics meet functionality.When it comes to indoor unit options, Fujitsu and Mitsubishi offer a range of possibilities, including wall-mounted units for those seeking space-saving solutions, ceiling cassette units for a discreet and stylish appearance, and floor-standing units for added flexibility in room placement.


But what about the great outdoors?

The placement of the outdoor unit is a crucial consideration. If you get it wrong, you’ll find that it’s noisy, and ruining your outdoor chill environment. Plus, ideally, it’s not aesthetically terrible.

The good news is that both Fujitsu and Mitsubishi recognise the need for flexibility and space requirements. With careful planning and innovative design from your installation technicians, both brands ensure that their outdoor units can be positioned in a way that suits your specific needs and space constraints.


DIY Installation

Installation, a key factor in the air conditioning journey, presents its own tale of choices. Both Fujitsu and Mitsubishi offer options for do-it-yourself (DIY) installation, catering to the handy homeowners who prefer a hands-on approach, but you’re not allowed to DIY in Australia. Professional installation is critical, as you legally need a qualified electrician for installations. Using a specialist like Coalfiled’s Climate Control to ensure optimal performance and adherence to warranties and Australian safety standards.

Overall Aesthetics

In the battle of aesthetics, Fujitsu wins in our opinion, but in fairness, they’re both a lot better than some of the competitors. Ideally, an AC unit should blend into the background, and this often hinges around the installation job you get too.



Lastly, maintenance is the telling truth about the quality of an AC unit, and Fujitsu again is our preferred manufacturer. The units are well built, simple for technicians to operate and logical. With regular cleaning, filter replacement, and overall upkeep from a professional AC maintenance company, you’ll get optimal performance and longevity.

Reliability, Noise & Durability

When it comes to brand reputation, both Fujitsu and Mitsubishi have earned their stripes but Fujitsu is the market leader in our opinion. That said, with a volume of satisfied customers and positive reviews, both brand’s track records speak volumes. Visiting their official websites reveals the dedication these brands have towards ensuring customer satisfaction.
Fujitsu are renowned for being the quietest air conditioners on the market, delivering more air at lower noise levels. Sound is something that people underestimate, so if you’re on the fence, then consider this high on your priority list.

Warranty coverage is always a deciding aspect of any purchase, and both Fujitsu and Mitsubishi don’t disappoint. Offering generous lengths and favorable terms, their warranties provide peace of mind and protection for your investment. Mitsubishi offer a whopping 12 year warranty on certain parts and the compressor, whereas Fujitsu offers a 5 year warranty on the units. Our professional opinion on this is that if you’re going to have a major problem, this will occur in the first 12 months of operating your air conditioner. Also, an AC unit should be replaced after ten years to ensure energy efficiency, at the very least. In the realm of longevity, in our experience, Fujitsu lasts longer than Mitsubishi and the durability of parts from Fujitsu is superior.

Pricing & Value for Money

When thinking about price, you need to consider ongoing costs. You’ll also never regret buying quality, so we encourage you to spend a little extra which will save you in the long run. Fujitsu is the more expensive brand for the initial unit cost, but this shouldn’t be a deterrent.

Energy savings play a crucial role in long-term cost savings over the lifespan of your unit. Fujitsu and Mitsubishi, with their commitment to energy efficiency, both strive to minimise your utility bills over-time.

Here’s a table to demonstrate the potential savings in buying a Fujitsu unit, over time in energy efficiency. However, please note, these figures are calculations internally, and you should do your own research for true accuracy.


Year Initial Cost (Mitsubishi) Initial Cost (Fujitsu) Cumulative Energy Savings (Fujitsu) Cumulative Maintenance Savings (Fujitsu) Total Costs (Fujitsu) Net Savings (Fujitsu vs. Mitsubishi)
0 $1,800 $1,899 $0 $0 $1,899 -$99
1 $54 $18 $1,827 $27
2 $108 $36 $1,755 $99

9 $486 $162 $1,251 $603
10 $540 $180 $1,179 $675


Beyond the basic cost, let’s explore the added value of additional features. Fujitsu and Mitsubishi offer a range of extras, from advanced programmable settings to innovative air filtration systems. Assess the value these features bring to your comfort and well-being as you make your decision.

Maintenance and repairs are inevitable over the lifespan of an air conditioner. Both brands are similar in their servicing requirements, but we’ve found Fujitsu to be more reliable.

If you only need the air conditioning short term, the best approach could be short term aircon hire over purchasing a brand new unit.



In conclusion, our professional opinion is that Fujitsu is the clear winner. There’s no trickery in their marketing, the units go the distance, the energy consumption is outstanding, they are market leaders in noise levels and technology;  the parts are readily available, and their warranty is on-point. Mitsubishi is a good brand, but we’d pick Fujitsu, all day, every day.
