James has been one of the easiest Contractors to deal with, that we engaged to help us with the new building, he has a real solution-focused approach and is super friendly as well.
We came across a couple of issues along the way, that James managed to find a solution for us. He has also kept in touch with us now that we are open, to make sure things should be working as they should be.
I would have no hesitation in recommending James, from Cool As, to anyone that was looking to engage or use his services. If you wanted to know anything further, please feel free to call me as I’d be happy to discuss any relevant details.

James went above and beyond what I expected when repairing multiple issues with our Gree ducted heatpump/AC unit.

After a previous technician’s failure to diagnose the problem, James identified the first issue within a few minutes and was extremely helpful in fixing that and solving a second problem found later. He was a pleasure to deal with; friendly, fast, clearly very experienced with a lot of expert knowledge – at the top of his game. Very highly recommended!

Professional and cost effective. James is a total pro, we’re so happy with our install and wouldn’t hesitate to recommend him for any of your heating or cooling needs.

Fraser Simpson

Since 2020 James has been providing us with hi-wall heat pumps and ducted heating/cooling solutions.

James has installed a large number of systems for us and our clients. He installed a large ducted system in my own home, which we are really pleased with. He assists us with design ideas, meets with our clients to discuss their needs and offers advice. We have only ever had great feedback from our clients about James and the service provided by Coolas, which makes it very easy for us.

We are very happy with the service and finished products James provides, and the after sales service is awesome. We recommend James and Cool As very highly.
