Few months back i had a problem with my Car A.C, mine was a 98 model Zen.A.C gas need to be filled.
Consulted MASS for AC service at Srikakulam,A.P They said that the gas used in my car is R12 and its been banned, and thus they will not able to top up the gas. They said if i want they can get a conversion kit fitted with them, costs 8k along with new R134a gas filling.
they recommended me to go for new R134a.I consulted some local A.C mechanic and got servicing along with R12 gas filling for Rs.1000.
After that I did some research and came to know that Dupont had come up with a drop-in replacement gas for R12 called Isceon MO49 Plus (R-437A) and it was available.
DuPont? ISCEON® MO49Plus (R-437A) Refrigerant
The good news is that nothing needs to be changed, not even the mineral oil in the compressor and MO49+ is going to be available in the future since it has no environmental issues like ozone layer damage etc. All these AC guys are intentionally not disclosing this info and recommending to change the entire kit for using R134a and making tons of money. Ask your AC guy or at service station people and see how they act like they are unaware about it. Every car A/C shop just said that R12 is not available anymore, so the only option is to convert to use 134a, either by servicing the compressor, changing the pipes, condensor & evaporator, or by going for a change of everything barring the evaporator. They did not speak of Dupont’s MO49+ though being in the car A/c industry, they should have been aware of it. I guess they stand to rake in much more money by replacement/conversion than by suggesting an alternative gas!
MO49 Plus is available from Dupont distributors at retail cost of Rs 350 per can of 340 gms.
