After Sales


Having your air conditioner serviced regularly is very important. Not only are you meeting your manufacturer warranty obligations, but you are also staying abreast of any legal requirements.

Graymac can propose a service maintenance program to capture all your assets and provide a comprehensive schedule so that all your plant can be maintained to optimum conditions and essentially protecting your investment.

Breakdowns can occur at the worst possible time. We know you want your system back up and running ASAP. At Graymac, we strive to prioritise our jobs so that you are not waiting too long to have your system repaired. We provide a written report and quote for all repairs once the problem has been diagnosed. Granted some repair situations are out of our control, but we endeavour to keep you up-to-date so that you’re not kept in the dark wondering. We utilise a trusted job management system that enables us to keep track of our all our requests, staff and stock levels, ultimately delivering to you – satisfaction.

Home wall air conditioner smells funny? Over time from use, your air conditioner builds up dirt and mould that regular servicing cannot fix. Breathing in mould particles can have effects on your respiratory system and cause other health issues. Graymac can fix this problem with our strip and clean service. Our technicians apply a wetting agent on all the areas of dirt and mould and with the assistance of pressure and bag cleaner,  effectively remove all the contaminates.

After our visit, your system will –

  • Be more hygienic and emit no more odours when operating. 
  • Look like new again. 
  • Operate and cool more efficiently. 
  • Cost less $$ to operate. 


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.
