Mitsubishi Electric vs Daikin Air Conditioner
Mitsubishi Electric and Daikin are the two most respected premium air conditioner brands in Australia. Both are Japanese manufacturers with long track records of reliability and innovation. If you're buying a split system air conditioner and want the best, the choice often comes down to these two brands. This guide compares them side by side.
Brand Overview
Daikin is the world's largest air conditioner manufacturer by revenue. The brand is known for being at the forefront of technology, particularly inverter compressor development, and has a very strong service and installer network in Australia.
Mitsubishi Electric is part of the Mitsubishi group and focuses heavily on heating and cooling. Their Australian range is known for exceptional cold climate heating performance and very quiet operation, particularly at low fan speeds.
Efficiency and Energy Rating
Both brands produce highly efficient inverter air conditioners with strong star ratings. Daikin's Cora and Ururu Sarara series and Mitsubishi Electric's Reverse Cycle series both offer 5–6+ star energy ratings on their premium models.
Edge: Tie (both excellent; specific models vary)
Cold Climate Heating
This is a meaningful differentiator. Mitsubishi Electric's Hyper Heat models are specifically engineered for cold climate heating and can deliver full rated heating capacity at outdoor temperatures as low as -15°C (while standard units begin to lose capacity below 0°C). This is particularly important for Blue Mountains, Southern Highlands and Canberra-adjacent customers.
Daikin also has cold climate capable models but Mitsubishi Electric's Hyper Heat has a stronger reputation in extreme cold conditions.
Edge: Mitsubishi Electric (for cold climate heating)
Quiet Operation
Mitsubishi Electric is widely regarded as producing some of the quietest indoor units in the world. Their premium models operate at as low as 19dBA on the lowest fan speed — quieter than a whisper. Daikin's premium models are also very quiet but Mitsubishi Electric has a slight edge in this area.
Edge: Mitsubishi Electric
Reliability and Longevity
Both brands have excellent reliability records in Australia. Both carry 5-year warranty periods on the wall unit and outdoor unit. Independent HVAC service technicians generally rate both brands as very durable.
Edge: Tie
Price
Mitsubishi Electric tends to be priced slightly higher than comparable Daikin models. Both are premium products — expect to pay $1,400–$2,500+ for a quality 2.5–5kW split system from either brand (supply only, before installation).
Installer Network
Daikin has a larger network of Daikin-accredited installers (Daikin Comfort Dealers) in Australia. Mitsubishi Electric also has a strong installer network. Both brands recommend using accredited installers for warranty purposes.
