Daikin is the world's largest HVAC manufacturer - not just by a little, but commanding roughly 11% of the global market with 4 trillion yen in annual sales. The Japanese company operates 100+ manufacturing facilities across 173 countries. When Daikin bought Goodman in 2012 for $3.7 billion, it instantly became the dominant force in North American residential HVAC.

Here's what confuses people: Daikin, Goodman, and Amana all use the same QMID (I7Q6) because they're all manufactured by the same parent company. The brands serve different market segments - Daikin-branded equipment is positioned premium, Amana mid-tier with warranty emphasis, Goodman as the value play - but they share manufacturing DNA and the same tax credit eligibility.

In 2022, Goodman Global was renamed Daikin Comfort Technologies North America, though the Goodman and Amana brand names persist for product marketing. The Daikin Texas Technology Park in Waller is the largest HVAC manufacturing facility in North America, producing equipment for all three brands. North America now generates more revenue for Daikin than any other region.
