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.
