Mitsubishi Electric vs Daikin Air Conditioner: A Head-to-Head Comparison
Mitsubishi Electric and Daikin are the two most respected air conditioner brands in Australia. Both are Japanese, both have decades of proven reliability in Australian conditions, and both are routinely specified by air conditioning installers as their top recommendations. So how do they differ, and which should you choose?
Brand Overview
Daikin
Daikin is a Japanese company and the world's largest air conditioning manufacturer by volume. They manufacture their own compressors — a key differentiator — giving them control over the core component of an air conditioner's reliability and efficiency. Daikin has a very strong presence in Australia, with comprehensive spare parts support and a wide network of authorised installers. They offer a 5-year parts and labour warranty on most residential units.
Mitsubishi Electric
Mitsubishi Electric (not to be confused with Mitsubishi Heavy Industries, a separate brand) has been in Australia for decades and is consistently rated highly by installers for reliability. Their signature features include Plasma Quad Plus air purification and the MELCloud smart control platform. Mitsubishi Electric offers a 7-year compressor warranty on most residential units, one of the best in the industry.
