Anyone Recharged Your Own A/C?

I would not recommend it. Actually, I wouldn't use anything like that on ANY car, unless I started with a completely discharged and vacuumed out system.

The problem with using those is that there's supposed to be a certain amount of refrigerant in the system. In weight, not pressure. So if your system is low, you're adding blindly and run the risk of overcharging the system. The pressure gauge on the bottle helps, but it's not accurate because it doesn't tell you how much refrigerant is in the system.

Thanks, I may have used the term "recharged" incorrectly. Perhaps "topped off" to raise a low refrigerant level would be more accurate.

Is there still a risk of overcharging in this case? If I have my INDY do the service, will they proceed any differently, albeit perhaps with a better set of gauges?
