Did u install a good tint films at all windows & windshields? Usually when i drive alone on a hot day, i set the temp to 25-26 deg will do. If got passengers, i usually set the temp to 23-25 deg..24 deg is cool enough already. But of course, i've installed a good solar & security tint film which prevent most of the sun heat from penetrating into the cabin ..& i also did the aircond pipe insulation (DIY) that might also helps

Hi Bro, thanks for reply. Solved.

Yeap, it is tinted. as you said, 23 - 24 is sufficient.
I think there is some problem whtrader's AC. Even my 12 years old iswara (AC, all original, no more tinted, peel off) does not take 20 minutes to cool.
Hi Bro, thanks for reply. Solved.

Hi Bro, 23 to 24 deg?

How is that possible? Mine need to set 18? If not it will be hot even under normal weather.
By the way can share some pictures here of the installation.
Will try to take some photo in the weekend, currently car is not with me......is very simple only, if not mistaken, you can find some info in internet.
i) u just need to find those insulation hose (those similar in your house air con),
ii)locate the cold part of the AC pipes (u can feel with your hand after u run your aircond). Warning, do not touch directly with your hand as there are a few pipes which are hot (also, do not insulate these pipes). Just feel by putting your hands near it, or if you have those temperature gun, it is helpful. Another helpful tip is, those cold pipes will have some water condensation on it.
iii)wrap it and tie with cable tie,etc...........
There are some insulation that comes with adhesive, but it can be very messy after that.
Hi Bro, thanks for reply. Solved.
Updates on my aircond. Solved.
How it was solved?
After speaking to my trusty old air cond service friend he commend me to remove the cabin air filter and test.
Upon removing the air filter the problem seems to be solved. The air coming out of the vent is much cooler and stronger.
During hot day it cooled faster too. In a sense the air filter is limiting the air flow to the cabin hence delaying the cooling effect.
And by the way it was install upside down and choked with dust.

.
Also changing the aircond setting from 18 deg c to 22/24 deg c might have helped. Not sure about this. But will continue to monitor.
Thanks for all the support and advice.
Now I will install the cooling pipe insulation.
