Biggest mistake I made in my 75 years on this planet was to buy a Mitsubishi split system from Air Conditioning Expert. He had 3 attempts at fixing leaking pipework over a period of about a fortnight. After his initial installation he refused to acknowledge that it was his lack of brazing experience that was the root-cause of the loss of refrigerant, so he lodged a warranty call with Mitsubishi. When Mitsubishi troubleshooters came out to investigate, the only problem they found was a leak in the brazing joint made by Simon. So, after his third attempt to provide a leakproof also failed, I told him I'll get Mitsubishi to send out someone that was able to provide a leakproof connection, Upshot was that it cost me an additional $222.75, because the warranty callout was clearly NOT a warranty issue. Normally the person lodging a warranty callout would be liable for the cost, but he flatly refused pay. And then I had to pay another Installation fee of $726.00 to finally get everything hooked up and working.
So, if you are in the market for a new air con, think twice before buying from him.

Oh – I forgot to mention the damage that he did, with his ladder on the wall next to the front and the numerous holes he burned into out vinyl flooring in his attempts to braze some copper pipe.

Approximate cost: $2800
