About Us

“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.

The Seeley family business has grown from humble beginnings into Australia’s largest air conditioning and ducted gas heating manufacturer and a global leader in the HVAC manufacturing industry, developing ingenious, energy-efficient cooling and heating products.

Today, more than 80,000 products and 1,500,000 components are manufactured in Australia every year, and sold through more than 300 independent dealerships in Australia and an extensive network of distributors and retailers across Europe, Asia, the Middle East, Africa, South America and the USA.
