"We had a great experience with Johnston Air Conditioning. We purchased a small unit that needed to be installed, Andy was quick to respond to our request, was well priced in comparison to other quotes and provided some great advice on the best position for the unit to maximise our air flow which has really helped the family over the hot summer days.

We couldn’t be happier with the service and Andy’s honesty & professionalism throughout…"
