About Us

A FEW WORDS

About OUR STORY

GRAYMAC was born from the amalgamation of two successful companies operating in Brisbane and the wider region. The Directors, Martin and Jon have a wealth of industry knowledge and have a combined experience in air conditioning in excess of 41 years.  

Martin Gray owned and operated MJG Air, with a team of skilled tradespeople and technical staff since 2013. His best mate and friend Jon MacDonald had grown his company, MacDonald Air Conditioning Services, from humble beginnings in 2006 to completing large commercial installations throughout Brisbane. 

Many discussions took place on how two small companies could serve their client base better by improving the basics in customer service – response times and the ability to capture a wider service area, thus Graymac Pty Ltd started in 2017. In that time the company has progressed, and we have successfully delivered to our client’s, large scale projects as well as maintaining quality service to our existing valued customers. 

Our mission - provide a quality experience to our clients based on friendliness, courtesy and reliability. We trust Graymac can meet your air conditioning requirements, both big or small.

Testimonials

I had the pleasure of meeting Martin Gray initially for servicing my business and building in 2004. Since then I have used GrayMac air-conditioning for a number of construction and renovation projects that needed air-conditioners installed or reticulation air solutions. I can honestly say it’s always a pleasure working with them, they offer solutions to a problem and keeps the job moving in a timely manner. GrayMac has always delivered a high standard of work. I have no hesitation in recommending them to anyone interested in the air needs. Bill Tsiknaris

Since 2014, T&J Bowden Constructions has chosen Graymac Air-Conditioning Services as our preferred supplier and installer for all of our air-conditioning requirements, including both fully ducted and split system air-conditioning. Over these past six years, Jon and his team have worked at numerous sites for us. We’ve always found Graymac’s pricing to be very competitive, and their quality of work and professionalism of service are far superior to others in the industry. One of the things that T&J Bowden Constructions prides itself on is the courtesy and respect that our sub-contractors show to firstly our clients, but also to other trades working on the site. Jon and his staff have never let us down. Dealing with Graymac Air Conditioning Services has made this aspect of our business completely stress-free and we hope to continue our association with them for years to come.
