Let’s compare the energy efficiency of two models with similar rated capacity and pricing between Daikin and Mitsubishi.
| Air conditioning Model | Energy Efficiency in Cooling AEER/EER | Energy Efficiency in Heating ACOP/COP | Our Rating |
| Mitsubishi 2.5kW MSZ-EF Series | Up to 4.60 | Up to 4.57 | ⭐⭐⭐⭐ |
| Daikin Alira X – FTXM25WVMA / RXM25WVMA | Up to 5.38 | Up to 5 | ⭐⭐⭐⭐⭐ |
Energy Efficiency Ratio (EER) measures your air conditioner’s performance under specific peak conditions, typically at high outdoor temperatures. Annual Energy Efficiency (AEER) takes a broader approach. Instead of focusing on peak conditions alone, it considers varying temperatures and cooling demands from spring through fall, providing a more realistic picture of year-round efficiency. Higher EER or AEER numbers indicate better efficiency. Units with high ratings produce more cooling per unit of electricity consumed, translating to lower energy bills and reduced environmental impact.
The Daikin ac brand performs slightly better compared to Mitsubishi in terms of energy efficiency in heat or cool. Daikin specialises in air conditioning products, while Mitsubishi’s product range extends beyond smart air conditioners.
This is all great and all, but what does this mean in the real world? How do these ratings translate to savings?
Consider the following scenario:
|
Brand / Model |
Rated Power Input (Cooling) |
Rated Power Input (Heating) |
Summer Cost (Cooling) |
Winter Cost (Heating) |
|
Daikin Alira X – FTXM25WVMA |
0.47 kW |
0.64 kW |
$110.01 |
$149.81 |
|
Mitsubishi MSZ-EF Series (2.5 kW) |
0.57 kW |
0.60 kW |
$133.42 |
$140.44 |
With a typical inverter part-load factor applied, the Daikin Alira X (2.5 kW) proves slightly cheaper to run for cooling, saving around $11.70 over a three-month summer compared to the Mitsubishi MSZ-EF. In winter, the Mitsubishi edges ahead by about $4.68 thanks to its lower heating input. Overall, both systems deliver excellent efficiency, but minor differences in power draw can still affect seasonal running costs.
Hunter Valley’s temperature swings demand versatile solutions, reverse cycle air conditioners shine by keeping homes toasty in winter and cool in summer, combining efficiency with flexible comfort.
For maximum energy savings, set your system to 18 to 20°C in winter and 25 to 27°C during summer, as leading consumer sources recommend. Fine-tune settings for daily conditions: use economy mode and close doors to minimize heat loss or gain, and adjust fan speed to boost efficiency.
A reverse cycle air conditioner is a specific system that provides both cooling in summer and heating in winter by reversing the refrigerant flow, unlike standard air conditioners which only cool.
Both the Daikin Alira X and Mitsubishi MSZ-EF 2.5kW are premium reverse cycle units in Australia, tailored for climate-smart heating and cooling with top efficiency.
Getting your Daikin Alira X or Mitsubishi MSZ-EF 2.5 kW air conditioner professionally installed is the first step toward reliable performance. A licensed HVAC technician ensures the system is correctly sized, securely mounted, and properly charged with refrigerant for maximum efficiency.
Once installed, routine care helps keep your unit running smoothly. Clean or replace filters every few months and make sure the outdoor unit is free from leaves, dust, or obstructions that can restrict airflow.
Even with regular upkeep, professional servicing once a year is essential. A qualified technician can check refrigerant levels, inspect electrical components, and detect early signs of wear before they lead to bigger issues.
Regular maintenance doesn’t just improve efficiency. It extends the life of your system and maintains healthy indoor air quality. If your air conditioner isn’t performing as expected, our team can restore it to peak condition quickly and safely.
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.
In 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. Daikin models are more expensive to purchase but may be cheaper to operate over the long run because of their higher efficiency ratings. As for installation costs, both brands should cost about the same to install. Call us for a detailed quotation of air conditioner installation costs.
So, which is the better choice? It comes down to your needs, the environment we’re installing your unit in, and your budget. If you call us, we’ll take the hassle out of the decision making process for you, by visiting your property and assessing the area and best installation methods. If you’re looking for an air conditioner that’s affordable and easy to install, then Mitsubishi Electric is a good option. However, if you want an air conditioner that’s more efficient and has a longer lifespan, then Daikin is worth considering.
When choosing between Daikin and Mitsubishi air conditioners, it’s important to consider the features and functionality that each option offers.
Again, let’s do a comparison of Daikon vs Mitsubishi when it comes to air conditioning features:
| Air conditioning model | Air filtration or air purifying features | Our rating | Energy saving technology | Our rating |
| Mitsubishi 2.5kW EF Series | Mitsubishi’s air purification feature is called “Nano Platinum Deodorising Filter,” which removes particulate matters as small as 2.5 micrometers (PM2.5), such as bacteria, virus, allergens, vehicle emissions, mould and dust. | ⭐⭐⭐⭐⭐ | This model has an inverter system that will help you save on energy usage through automatic power adjustment that provides the exact cooling or heating amount your room needs. | ⭐⭐⭐ |
| Daikin Alira X – FTXM25WVMA / RXM25WVMA | Daikin’s streamer technology has advanced air purifiers that remove odours, while filtering bacteria and harmful substances. | ⭐⭐⭐ | Daikin air conditioning uses neodymium magnets, which can boost energy efficiency up to 40% compared to standard ducted air conditioners or split air conditioners. | ⭐⭐⭐⭐⭐ |
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.
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’s 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.
The table below shows the recommended cooling capacities (in kilowatts) for different room sizes, helping you match your air conditioner to your space. An undersized unit will struggle to cool the room effectively, leading to higher energy use and uneven temperatures, while an oversized system may cycle on and off too often, wasting power and wearing out components faster. By choosing the right capacity for your room size, you ensure consistent cooling, lower running costs, and a longer lifespan for your air conditioner.
| Room Size | Typical Examples | Suggested Cooling Capacity |
|---|---|---|
| Small (up to 20 m²) | Bedroom, study, or compact kitchen | 2.0 – 2.5 kW |
| Medium (20 – 40 m²) | Bedroom with ensuite, or small lounge | 2.5 – 5.0 kW |
| Large (40 – 60 m²) | Large bedroom, medium lounge, or spacious kitchen | 4.0 – 6.0 kW |
| Extra Large (60+ m²) | Open-plan living areas or large lounges | 5.0 – 9.0 kW |
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.
