Is Mitsubishi AC Better Than Fujitsu?

Mitsubishi and Fujitsu are two of the leading brands in the air conditioning industry, offering top-of-the-line units and air source heat pumps with advanced technology and energy-efficient features. When comparing these two brands, it ultimately comes down to specific requirements and finding the one that best meets your needs.

Mechanical Reputation and Performance

Mitsubishi is known for its exceptional mechanical reputation and slightly better performance compared to Fujitsu. Mitsubishi’s air conditioning units are engineered with precision and attention to detail, ensuring reliable and efficient operation. Their systems are designed to withstand the test of time, making them a popular choice among homeowners and HVAC professionals.

On the other hand, Fujitsu also boasts impressive performance and technology, but Mitsubishi may have a slight edge in this area. Mitsubishi’s advanced compressor technology, for instance, allows their units to operate at higher efficiency levels, resulting in lower energy consumption and utility bills.

Noise Levels

When it comes to noise levels, Mitsubishi mini-splits have a clear advantage over Fujitsu. The quietest Mitsubishi indoor unit operates at a mere 19dB(A), which is quieter than the sound level of normal breathing (25dB(A)). This makes Mitsubishi’s systems an excellent choice for bedrooms, home offices, or any other space where a peaceful environment is desired.

Fujitsu’s units, while still relatively quiet, may not be able to match Mitsubishi’s impressive noise reduction capabilities. This can be an important factor for homeowners who prioritize a peaceful and serene indoor environment.

Air Filtration and Deodorization

Mitsubishi’s air conditioning systems are equipped with a multi-stage, platinum deodorizing filter that not only captures and removes contaminants from the air but also absorbs and cleans the air of odors. This advanced filtration system helps to maintain a fresh and clean indoor environment, making it a valuable feature for those with allergies or sensitivities.

Both Mitsubishi and Fujitsu use washable filters that can last up to 10 years with proper maintenance, ensuring long-term air quality and reducing the need for frequent filter replacements.

Dehumidification Modes

When it comes to dehumidification modes, Mitsubishi’s units have been known to overcool a room and should not be left on for more than an hour or two. This can be a potential drawback, as it may lead to increased electricity costs and discomfort.

It is unclear if Fujitsu’s units have the same issue with dehumidification modes. However, it is generally recommended not to rely on dehumidification modes as a replacement for traditional dehumidifiers, as they may not be as effective in controlling humidity levels.

Styling and Pricing

While Mitsubishi has a slight edge in performance and technology, Fujitsu offers a more modern and stylish design for their air conditioning units. This can be an important consideration for homeowners who prioritize the aesthetic appeal of their HVAC system.

In terms of pricing, Fujitsu is typically 5-10% lower than Mitsubishi for most contractors and online retailers. This can be a significant factor for those on a tighter budget or looking to maximize their investment.


Mitsubishi and Fujitsu are both excellent choices in the air conditioning market, each with their own unique strengths and features. Mitsubishi’s superior mechanical reputation, performance, and noise levels make it a top contender, while Fujitsu’s more modern styling and lower pricing can also be appealing.

Ultimately, the decision between Mitsubishi and Fujitsu will depend on your specific needs, preferences, and budget. It’s essential to carefully evaluate the features and benefits of each brand to determine which one best suits your home or commercial space.
