Half a century of air conditioning excellence

In the early sixties, Dunnair manufactured the well-received Airtemp range of air conditioning products under the stewardship of founder and director, Rob Dunn. More success followed when Dunnair’s South Australian office – one of five interstate operations headquartered in Melbourne – began producing its own range, selling under the Chrysler name. In 1983 the manufacturing arm of the company was sold to EmailAir, allowing Dunnair to focus its efforts on sales and service.

Dunnair went on to secure several high-profile maintenance contracts with multinational companies, notable among them the McDonald’s chain of fast food restaurants. The company was also selected as one of few contractors tasked to maintain the Cosatron installations at Crown Casino.

It was the first company in Victoria to import Sanyo air conditioning units, and in the early 1990s began to badge Derby by Dunnair wall mounted split units, which continued well into the mid 90s.

In 1994, Dunnair was bought by Multistack and renamed Dunnair International – and in 2004, Ernest Ugazio acquired its sales and service departments. This led to the company being divided into two separate entities. Dunnair International focussed on Multistack Chillers sales and spare parts while Dunnair Australia began design and development of a split ducted and rooftop packaged range to be manufactured in China.

Today, Dunnair’s range of air conditioning equipment is manufactured by two associate factories in China, and comprises 16 product lines on some 600 different models, plus made-to-order products. The entire Dunnair range is available through Davis & Spence.
