Mitsubishi Electric vs Daikin Air Conditioner: A Detailed Comparison
Mitsubishi Electric and Daikin are the two most respected premium air conditioner brands in Australia. Both are Japanese-engineered, both are known for outstanding reliability, and both are significantly more expensive than Korean or Chinese alternatives. If you're deciding between the two, this guide explains the key differences to help you make the right choice.
Brand Backgrounds
Mitsubishi Electric
Mitsubishi Electric (not to be confused with Mitsubishi Heavy Industries, which makes a separate range of air conditioners) is part of the Mitsubishi Electric Corporation, a global leader in power and electronic equipment. Their split system air conditioners are known for extremely quiet operation, excellent energy efficiency and reliable performance in Australian conditions.
Daikin
Daikin is the world's largest manufacturer of air conditioners. Founded in Japan in 1924, Daikin pioneered many of the technologies that are now standard in the industry, including the inverter compressor and R-32 refrigerant. Daikin has a strong presence in the Australian commercial and residential markets.

Noise Level: Mitsubishi Electric's Key Advantage
If quietness is your top priority — perhaps you're installing in a bedroom, home office or studio — Mitsubishi Electric has a slight edge. Their premium models are among the quietest split systems ever measured, with some rated at just 19 dB(A) on the lowest fan setting. That's roughly the volume of a whisper at 1 metre distance, and barely audible in a quiet room.
Heating in Cold Conditions
Both brands perform well in cold conditions. Mitsubishi Electric's Hyper Heating (H2i Plus) range maintains full heating capacity down to -15°C ambient temperature, which is well beyond what most Australian homes require. Daikin's equivalent cold-climate models also perform excellently down to -10°C to -15°C.
Which Should You Choose?
Choose Mitsubishi Electric if:
- Noise level is a priority (bedroom, nursery, home office)
- You want very quiet heating and cooling
- You prefer a slightly more conservative design aesthetic
Choose Daikin if:
- You want the world's largest air conditioner manufacturer
- Installer support and parts availability are important (Daikin has the widest installer network in Australia)
- You're looking at multi-zone or commercial systems as well as residential
