Honda Accord 1996 A/C R12a Refrigerant to refill R134a
In the past two years my A/C system been checked twice for leaks with negative results that is, they couldn't find the leak point. They'ld refilled it with R134 (by an amount of 24 oz) and with that the A/C would work for the rest of the summer. The August of 2004 was the last time I had my A/C checked and once again, this summer, the A/C is not producing cold air. Assuming that the leak is small and that this year too I have only lost an amount of the refrigerant similar to last year (24oz) I bought the RedTek 12a Recharge kit (which contains 2 cans, each equivalent to 16 oz of R134a). I did not realize that the refrigerant in my system was R134A and as they say is it illegal to mix it with a different type like the R12a I bought.
The literature I was able to find in the internet site for RED TEK says: DO NOT MIX REFRIGERANTS. Mixing refrigerants is illegal in Canada and the US ...
My questions are:
Does anyone know the total amount of refrigerant in the A/C system for the 1996 Honda Accord 2.2L?
How can I measure the amount of refrigerant lost?
Why is it illegal to mix refrigerants when they say that the R12a is compatible with most existing refrigerants?
Should I first have the A/C system checked again by a certified garage and request that it is refilled with R12a so that next year I can refilled it myself in case it leaks again?
What are the risks of mixing R134a with R12a?
I will appreciate any help.
