For over many decades now, Mitsubishi continues to be a top brand for air conditioners in Singapore.

However, did you know that there are two brands of air conditioners under the Mitsubishi group? These are Mitsubishi Heavy and Mitsubishi Electric.

While Mitsubishi Heavy and Mitsubishi Electric have gone on to become the best-selling air conditioners in Singapore, many customers still do not understand the difference between the two.

While both share the same name, these two brands are completely different — from the production to the design and all the way to each aircon feature.

In this article, we give you a complete breakdown of each brand from Mitsubishi — from their best-selling features, pros, cons to other interesting facts you didn’t know you needed.

The Origin of Mitsubishi Heavy and Mitsubishi Electric

Mitsubishi Shipping Co. was established as a shipping company (now Mitsubishi Heavy Industries) by Yatoro Iwasaki in 1870. In 1873, the company name was changed to Mitsubishi Shokai. In 1921, by cutting off a factory in Kobe, Japan, Mitsubishi Shokai established another factory to focus on producing electric motors for ocean ships. In other words, Mitsubishi developed into two different electrical segments: Electric and Heavy.

From there, the two segments officially split into two small brands: Mitsubishi Heavy Industries and Mitsubishi Electric.

Telling Them Apart

You can completely distinguish a Mitsubishi Heavy Industries Aircon vs a Mitsubishi Electric Aircon through the model name of the air conditioner you use. Here’s how:

  1. Mitsubishi Heavy Industries’ name often starts with letters such as Mitsubishi SRK / SRC air conditioners, Mitsubishi FSH air conditioners
  2. Mitsubishi Electric Aircon's name often starts with letters such as Mitsubishi MS air-conditioners, Mitsubishi MSY air-conditioners

Mitsubishi Heavy Industries Aircon Units: Pros & Cons


1. Longer experience, the best reputation

Perhaps this is the primary advantage of Mitsubishi Heavy Industries' air-conditioning systems because of its longstanding reputation when it comes to quality. Since Mitsubishi was founded in 1870, it has achieved over a century of manufacturing experience and built a reputation for producing high-quality products. 

2. Maximizing energy savings

Mitsubishi Heavy’s air conditioners help you save maximum electricity thanks to their Inverter technology - an aircon innovation from Japan also being used in a lot of refrigeration equipment.

The energy-saving ECO mode integrated with the Mitsubishi Heavy Industries’ air-conditioning product line also helps the room temperature be adjusted appropriately. The air conditioner will gradually increase the temperature to keep you warm, depending on your body temperature.

3. Ability to cool quickly

Fast-cooling technology with 4-way flaps is a main factor that makes consumers appreciate Mitsubishi Heavy air conditioners. This technology allows the air conditioner to operate at a high intensity to cool the entire room quickly in just 1 minute.

After 20 minutes, the room temperature will be automatically adjusted to make you feel cool and comfortable. Hi-Power mode intelligently adjusts airflow to enhance cooling efficiency within 15 minutes, helping you dispel the heat quickly.

In addition to this, Mitsubishi Heavy also offers a sleep mode that allows you to adjust the ambient temperature with the body temperature to not feel cold at night, ensuring a sound and comfortable sleeping experience. This is especially suitable for families with young children.

4. Effective deodorization, air filtration

Thanks to the Solar Filter deodorizing filter located in the upper part of the air conditioner, Mitsubishi Heavy air conditioners help prevent unpleasant odors from food, musty smells, cigarette smells, etc.

Not only that, most of the lineup’s air conditioners are covered with tourmaline stone capable of emitting negative ions for 24 hours. The higher the concentration of negative ions in the air, the cleaner the environment will be.

5. There are many utilities to adjust

In addition to the main features of refrigeration, bacteria filtration, and electricity-saving, Mitsubishi Heavy air conditioners also have many other utilities that are highly appreciated by users.

These include the drying mode — a helpful feature to help the room dry out fast, leaving no room for any sign of wetness and humidity. Another feature is a self-diagnosing error mode that automatically detects any error and notifies the user through the error code displayed on the remote screen for quick self-recovery.

The lineup’s ability to automatically restart after a sudden power outage also saves owners both power and time. Gone are the days of waiting for the air conditioner to cool down and reset its features after each power failure.


1. Fan coil arrangement

Majority of Mitsubishi Heavy Industries Aircon review posts from consumers have mentioned issues with the air conditioners’ fan coils arrangement. These result in the aircon units easily getting dirty and being susceptible to attracting different types of dirt.

2. High maintenance

Although some device owners claim that it would be unattractive to put the fan coils too close together, it is worth noting that the device needs to be cleaned frequently. A clogged fan coil will damage your air conditioner's current efficiency and eventually lead to your air conditioning system failure entirely.

Mitsubishi Electric Aircon Units: Pros & Cons


1. High durability

Unlike Mitsubishi Heavy Industries air con systems, the Mitsubishi Electric air conditioners have fan coils far from each other. This makes air and heat pass through the fins quickly, ensuring that they minimize the possibility of getting clogged.

These fan coils also decrease the risk of the device overheating. Ultimately, this pro makes the brand’s air con collection more durable, easy to clean and manage than Mitsubishi Heavy Industries’ air con units.

2. Technologies in hot mode

A hot mode is an important part of an aircon that people often overlook because they’re rarely seen. However, the feature is necessary to help an air conditioner work well, save electricity, and be capable of operating under more complex environments.

3. Modern design, friendliness for users

Most of Mitsubishi Electric's air-conditioning designs are inclined towards modern, stylish, compact, easy to install, and user-friendly trends.

4. Airflow quality

Mitsubishi Electric air conditioners are equipped with a wide and long airflow feature thanks to a left-right reversing valve controlled automatically by the remote control. With the "Wide Vane" mode, you can easily adjust the airflow direction so that air can reach the corners of the room.


1. Cooling and power-saving performance

While Mitsubishi Electric is also equipped with energy-saving and user-friendly technologies, its fast-cooling and power-saving capabilities are still a bit inferior to the Mitsubishi Heavy Industries lineup of aircon units.

2. Very technical for older groups

Another downside to consider is that the air conditioners under this brand can be too high-tech for some users, causing compatibility issues among older groups.

However, these are only a couple of tradeoffs that interested buyers need to consider before purchasing. Overall, the Mitsubishi Electric aircon lineup is still a high-quality and top-notch aircon line in the industry.

Choosing The Best Product Line For You

Deciding the best brand between Mitsubishi Heavy Industries and Mitsubishi Electric will ultimately depend on your preference, needs and environment. When it comes to overall quality, performance and durability, time has proven time and again that both brands can deliver without any trace of doubt.
