Daikin is the world's largest HVAC manufacturer by revenue and one of only three companies (alongside Mitsubishi and Fujitsu) that both designs and manufactures its own mini split compressors. Their North American mini split lineup includes four series — Aurora (cold-climate premium), Emura (designer), Quaternity (advanced humidity control), and Fit (value) — backed by the industry's best warranty at 12 years on all parts.
