Seeley International is Australia’s largest air conditioning and ducted gas heating manufacturer and a global leader in developing ingenious, energy efficient cooling and heating products.

From Humble Beginnings in 1972

The extraordinary journey of Seeley International began in 1972 when Frank and Kathy Seeley took Seeley Bros from a sales and marketing company, and transformed it into a manufacturing company, grounded on, and sustained by, Innovation, which still leads the world today. Their four children – Barry, Jon, Tim and Kari – have all been involved in the business over the years.
