May i know how do we know whether they have re-fill the gas sufficiently? i have recently re-fill gas but still see some white bubbles in my cylinder, is that a sign that not enough gas?
1. If the bubbles show in ur receiver drier only once a while, it perhaps due to high temparature. It should be fine.
2. Turn On ur a/c, u should see clear refrigerant flow through the sight glass. Turn the system off and watch the sight glass. If there is refrigerant in the system, you'll see bubbles during the off cycle. If you observe no bubbles when the system is running, and the airflow from the unit in the vehicle is delivering cold air, everything is OK.
3. If you observe bubbles in the sight glass while the system is operating, the system is low on refrigerant.
4. Oil streaks in the sight glass are an indication of trouble. Most of the time, if you see oil in the sight glass, it will appear as a series of streaks, although occasionally it may be a solid stream of oil. In either case, it means that part of the charge has been lost.
Hope this information helps you.

plan to service my wife's myvi A/C...it has clocked over 80k mileage..any trusted,reliable workshop in Sri Petaling/Puchong area?..estimated cost for the service??..t.q

80,000 km should be about time to go for a service. Your cabin air filter will be quite dirty, is about time to change.
Cabin air filter is very important as many people dun really bother to pay attention for it. It will make sure the passengers inside your car can breath in clean air. Once it is completely dirty, u need to change it because it will eventually trap x6 times germs compare to open air that keep flowing in your car. The price just about Rm50.
As for the labour, normally it will be Rm150. Drier will be about Rm40. As for expansion valve, i guess still no need to replace it if your air cond still can feel the cold.
Est will be about, Rm 150 + 40 + 50 = Rm190. ( As the price will be vary depends of the item brand)
If you need more info kindly leave a message to my H/P 012-6969621.
COD or POSTAGE both are available for us.
