Efficiency Ratings

The efficiency of an air conditioner is important because it determines how much energy the unit will use. The higher the efficiency, the less energy the unit will use and the lower your utility bills will be. Daikin and Mitsubishi electric air conditioners both have high efficiency ratings.

Daikin units have a seasonal energy efficiency ratio (SEER) of up to 28 while Mitsubishi units have a SEER of up to 30.5. In terms of annual fuel utilisation efficiency (AFUE), Daikin units have ratings of up to 98 percent while Mitsubishi units have ratings of up to 96 percent.


Cost of Units & Installation – Daikin Vs Mitsubishi

If you’re looking for a high-quality air conditioner, you can’t go wrong with either Daikin or Mitsubishi Electric. Both brands offer models that are reliable and efficient, but size does count.

When it comes to cost, Daikin air conditioners are typically more expensive than Mitsubishi Electric models. However, this is not always the case – it really depends on the specific model you’re looking at.

Features & Functionality – Daikin Vs Mitsubishi

When choosing between Daikin and Mitsubishi air conditioners, it’s important to consider the features and functionality that each option offers. Here are some things to keep in mind:

-Daikin air conditioners come with a variety of features that can make your life easier, such as programmable timers, remote control operation, and energy-saving modes.

-Mitsubishi air conditioners also offer a variety of features, including different fan speeds, an auto-restart function, and a self-cleaning mode.

-Both brands offer models with inverter technology that can save you money on your energy bills.

-Daikin air conditioners tend to be quieter than Mitsubishi units.

-Mitsubishi units typically have a longer warranty than Daikin units.

Daikin Vs Mitsubishi Maintenance Requirements

It is important to consider the air conditioner maintenance requirements of each type of air conditioner before making a purchase. Daikin air conditioners require less maintenance than Mitsubishi Electric air conditioners. Daikin air conditioners have a self-cleaning function that helps to keep the unit clean and free of debris. Mitsubishi Electric air conditioners do not have this self-cleaning function and therefore require more frequent cleaning.

That said, you should always have your air-con units serviced annually to ensure your family is breathing healthy air and you’re operating the units within the warranty terms and efficiently.


Size Does Count 🌶️

Both Mitsubishi and Daikin offer 1.5-tonne ACs, which should be sufficient to cool a medium-sized room or area. However, it’s important to ensure that the AC’s cooling capacity matches the size of the room or area it will be installed in because if it is too small, it may struggle to cool the room effectively, while if it is too large, it may cool the room too quickly without removing enough humidity, leading to discomfort and wasted energy.

Here is a table that summarises the guidelines for selecting the right size air conditioning unit for a room in meters, for a 1.5-tonne air conditioning unit:


Room Size (in square meters) Recommended AC Unit Size (in kW)
Up to 14 3.5 (1.0-tonne)
14 to 23 5.0 (1.5-tonne)
23 to 32 6.0 (1.75-tonne)
Larger than 32 7.0 (2.0-tonne) or larger


Note that these are general guidelines, and other factors such as ceiling height, number of windows, and insulation of the room may need to be considered when selecting the right size air conditioning unit for a room. Consulting with a professional HVAC technician can help ensure that you choose the right size AC unit for your specific needs.



Choosing between Daikin vs Mitsubishi Electric air conditioners can be a daunting task, but by taking the time to consider their price, energy efficiency, noise levels, warranty coverage and other essential factors, you can make an informed decision that will serve your needs. Ultimately, let our professional installation technicians make an assessment and give you your best options to choose from. Both brands offer reliable products with great features so whichever one you decide to go with should help keep your home cool and comfortable during hot summer days.
