I had a failure of a Ducted system. He quoted for its repair in November. Came out with the part in late December , but it failed to work , then requoted and said it would be a month .
Had extreme difficulty getting him to make a proper written report , almost had to do it for him for the insurance claim . Then was uncooperative with all the follow up detail required for the claim to proceed . Then after promising to repair it but not till 31 Jan , Sam then in middle of January said he could not do the job .
Very bad service and operation . I reported it to the air con manufacturer who I was referred to him by as a registered repair agent who were not impressed either .
Maybe they are ok for new installations but not for complex service issues or major repairs in my observations .

Do NOT go hear unless u have time to burn, 4 doctors on duty - had an appointment made previous day - -2 Hours LATE !!!!!!!
And no update from reception- so so bad !!
There are other better run clinics .
Previous time I left a feedback form but I had no reply or response - just not interested in being accountable for their poor management.
