My wife and I recently had two Mitsubishi Heavy Industry air conditioners installed by Simon's crew and they have done a fantastic job. The communication from Simon was prompt and very informative (there's also plenty of excellent information on his website), and they turned up on time and smashed it out in the anticipated time-frame. It was very impressive watching them work. The price was fantastic too, so it was a no-brainer. Thanks very much for a job well done - we're both very happy and would not hesitate to recommend. Have a great summer!
