Energy Efficiency Comparison

Two energy-efficient air conditioning units in a modern home.

Mitsubishi and Daikin both make air cons that use less power. Let’s see which brand gives you more cold air for less money.

Mitsubishi Energy Efficiency Ratings

Mitsubishi Electric’s air conditioners stand out for their energy efficiency. Their SEER ratings can reach up to 30.5, proving they use less electricity while cooling more effectively.

This measurement shows Mitsubishi is a leader in creating units that help save on power bills and conserve energy. The company’s ducted systems, including the Mr Slim PEAD Series, PEA Series, and SEZ Series, offer cooling powers from 2.5kW to 22kW and exceed Minimum Energy Performance Standards (MEPS).

These high standards mean customers get top-notch performance without wasting energy.

Daikin Energy Efficiency Ratings

Daikin air conditioners shine in energy efficiency. Their units boast SEER ratings up to 28, leading the market in reducing power use. For heating, Daikin achieves an AFUE rating of up to 98%.

This means they turn nearly all energy into warmth for your home. The brand’s ducted systems range from 2.4kW to a powerful 24.0kW for cooling, ensuring comfort in any size space.

The Daikin Alira X split system stands out with AEER/EER scores of 5.33/5.38 during cooling and ACOP/COP figures of 4.97/5 when heating. These numbers highlight how effectively these models run throughout the year – using less electricity to cool or warm your rooms.

Such performance cuts down on energy bills and supports greener living by minimising environmental impact.

Cost and Value

Picking the right air conditioner is about more than just the price tag. It’s about finding great long-term value from energy savings and efficient cooling or heating.

Initial Purchase and Installation Costs

Mitsubishi and Daikin set their prices with care. A Daikin Premium Inverter 14kW ducted air conditioning unit costs about $4,999. On the other hand, Mitsubishi offers a 14kW ducted system as well, but also has a smaller 2.5kW split air conditioner for different needs.

The price for Daikin’s Alira X 2.5kW split system is around $1,064. Installation adds extra to these basic costs.

This means buying these systems comes with added perks like tech support and warranties that protect your investment over time. Energy ratings matter too – higher ratings can save money in the long run by using less power to cool or heat your space effectively.
