Vacuum air conditioner gas pipe when fitting

colins — Tue, 28 May 2013 10:43:42 +0800

I am wondering when the installers here don't vacuum the air conditioner when it is fitted. I have installed 15 units of air conditioner (Panasonic, York, Daikin, Sharp, Carrier) and never once any of these installations were vacuumed. I believe this is the main reason why air conditioner doesn't last more that a few years before the compressor went faulty. The air and moisture in the piping will cause inefficient of the cooling which leads to higher power consumption and eventually the degradation and breakdown and corrosion of the system.

Of many of the installations, I have purchased the air conditioner from an authorized dealer after calling the brand principal that I want to have the installation vacuumed. Every time I was told "no problem, its OK, sure can..." but end up having some ignorant installer fitting the air conditioner.

The installers will usually say " can one....no problem one....no need to vacuum one....install so many units also no problem...huh? what is vacuum...." So they are trying to say that they are smarter than the engineers/chemists/designers of the manufacturers.

This is a reflection of the lack of knowledge and professionalism of the air conditioner industry in Malaysia.

Has anyone experience an installation that vacuum the pipe first before gas is released / charged?

Australian university entry requirement

I would like to find out whether American high school test result (e.g. SAT I & II and American College Tests) can be used for Australian universities and whether there is any complication or difficulties to get acceptance?

What about the International Schools’ Assessment which is offered by a number of international school in Malaysia for up to Grade 10.

The situation is that a friend's child (Year 8) is currently enrolled in an American system school but would like to send his kid to Australia for studies in the future, he is contemplating whether he should get his kid to change school (to an Australian system one).

I can't seems to be able to find anything directly relevant on Google, hence the post here. I'd appreciate your input and pointers to information on the web (if any). Thanks in advance.

Hi,
Is it true that only Panasonic has 42" Full HD plasma TV (i.e. P42U30K)?
From the official websites, others such as Samsung and LG don't have any 42" Full HD plasma, but only those with 1024X768.
