Hi there I totally agree with you. Whoever that sees our story, to please reconsider when you want to service your aircon. Best to engage a realiable service company or go back to your agent where you got your aircon from, even if it means paying alittle more. My case happened last week. We engaged Homex as they came door to door offering steaming packages at very good price. With children hyper allergy to dust and bugs these days, we decided to use Homex and try their steam clean specialty. Appointment was made for 515pm but the technician came at 6pm. Servicing and checking of the indoor and 1 outdoor unit were done by 7pm. The last was the masterbedroom condensor unit where he had to open the unit to check the gas level. He broke the valve connecting the tubings. He said it was no big issue and said will repair the next day with a new spare part. The technician came the next day at 6pm. Attempted to repair and connect the valve. Brazing was required and he was not a specialist. Long story short - he melted the new spare part as well as the inner parts of the condensor. We had to change the whole outsoor unit, costing us almost $2000/-. It was a nightmare for us all! A simple servicing turned into a string of problems leading to unnecessary hefty sum of money.
