Our Story

Optimum Air is a technical solutions company, delivering end-to-end management of heating, ventilation, air conditioning, industrial and process cooling and building automation across New Zealand.

Our commitment to sustainability is achieved through a proactive, integrated approach to helping organisations achieve energy efficiency in innovative ways.

Optimum Air was founded in 2018 by Airmaster Australia, one of Australia's leading HVAC service solutions companies.


Airmaster was founded in 1988 in Melbourne from a small factory office. With an emphasis on service and relationships, Airmaster quickly attained high profile clients like Highpoint Shopping Centre and The Age building in iconic Spencer Street.

Airmaster opened a first interstate branch in Queensland in early 2000. In 2002, Airmaster established its first permanent office in New South Wales and today has a total of 12 branches Australia-wide.

Where once Airmaster predominantly carried out traditional prescribed service and maintenance of HVAC systems, modern advances in information technology, energy management, controls, automation and asset management now drive the company’s integrated service delivery model.

Optimum Air draws upon the vast industry experience to deliver Airmaster's range of award-winning services and solutions to the New Zealand market.

Celebrating its 30th Anniversary in 2018, Airmaster has grown to have 12 branches around Australia including offices in all capital cities and many regional centres. Airmaster is an industry leader with a 700 strong workforce made up of technicians, apprentices, engineering and support staff.

A geographically and technically-diverse workforce means Airmaster is able to respond quickly to customer requests, and being a single source technical services company means that when customers engage Airmaster, they only deal with Airmaster people.

Since its inception, Airmaster has built a winning culture based on employee retention and a deliver-at-all-costs attitude.


Airmaster’s apprentices and young staff members are among the most talented in the industry, and continue to be recognised through awards such as Box Hill TAFEs Apprentice of the Year and the ARBS Young Achiever awards.
