Hi bro Luckygo, I totally agreed with you. I have bought the aircon from aron last year(I did not even care which company he represent, I took up his service because of all the good comments about him in this forum) and I did agree that he has given me the best service from pre-sale to installation till after sales service. Aron always come back to us promtly with right advices regards to our concerns. I just get to know that aron has left the company and I began to worry after reading bro "aircon leaking" comments. Tim Wong is not giving us the confident that he will provide good after sales service. It is not easy to get someone knowledgable, responsible to fit into Aron's position. Imperial may be giving tim's time to get use to his new job but as a new house owner, I believe all of them cannot afford to have any mistake when comes to aircon installation.
