Team-BHP - View Single Post - Zen A/C Cooling problem

newcoolgadgets · 10th May 2008, 12:38

My 2006 Zen VXi has done 22,000 kms and with this being its 3rd summer, the cooling of the AC has gone down. The flow of air from the vents is also reduced by almost 30%.

I went to Cool World at Ghat Road, Nagpur, and he looked under the dash, pointed a torch, (there is a plastic box which houses the cooling coils, I guess) and said that the cooling coils are choked with dust. He said he will need to clean and wash the coils. In addition he also said that the system needs to be flushed with Nitrogen and the gas has to be refilled. The compressor needs to be topped up with oil too. The estimate for this entire job has been given at Rs. 1800/-

My questions are:

1. Is it possible to open the cooling box under the dash and clean the dust at home?

2. I suspect the main reason for the drop in cooling and the air flow from the vents is the dust accumulation in the cooling coil box. Is it necessary to go in for a complete refrigerant gas refill?

3. Is it possible to know the level of the refrigerant in the system by looking at the small glass window in the AC system under the bonnet. If yes, how to read it?

4. Is Rs. 1800 fair for the above job?

Please let me know your views. I need the AC to work efficiently soon, as the temperature here is already 45 degrees!
