About

Our company

The team at DJK Air Conditioning are your local air conditioning experts based in Tennyson, Brisbane. Operating since 1990, Derrick and our team of mechanics continue to gain the loyalty of our valued customers and build our reputation as one of Brisbane’s leading air conditioning companies.

DJK Air Conditioning was founded in 1990 by Derrick John Kennedy after he discovered his passion for sales. With an apprenticeship at Carrier Air Conditioning up his sleeve, Derrick gained around 10 years of experience in the industry at contracting firms such as AE Smith and Wylie, and Fridgrite where he took on a supervisory role. When he discovered the niche market of supplying specialised air conditioning services, Derrick decided to start his own business. With around 30 years of persistence and hard work, DJK has since grown from a small business to a reputable company in the industry.

We have worked with many major clients throughout our years of air conditioning installations and servicing. These include the Queensland Fire and Rescue Authority, Remax, Bank of Queensland, local schools and many more. As well our commercial work, DJK has developed a strong base of loyal customers that we can proudly say makes working not feel like work at all.

In 2001, DJK Air Conditioning was appointed the title of ‘Diamond Dealer’ by Mitsubishi Electric. This was a great reward that showed our dedication to work was paying off, as well as providing us with an incentive to continue in our profession. Our respected title has since allowed us to develop strong relationships with our supplier as well as many other air conditioning businesses, giving us industry knowledge and ensuring our continual growth as a local company.

We offer a range of services for both commercial and residential clients, from installing and maintaining air conditioning systems to selling products that contribute to strong and healthy systems. Check out our services page to find out more.
