Safe product for A/C recharge 997.2
Hi guys!
I need an advice about what product people safely used to recharge their A/C systems. I did the search but couldn't find specific details. The product they used at the Pelican parts I don't think is available any longer. My concern is that every product which has refrigerant and oil has the leak sealant as well which they advertize as "system safe". i wasn't able to find any product which just has R134a and oil.
What did you guys safely used in your 997s? Or should I just call it a day and take the car to the dealer for A/C service?
Thanks a lot in advance!

Anytime I've used a recharge system on my non-P cars I ended up going to a local indie afterwards to do it right. It never worked as advertised for me. I'm convinced a DIY'er like myself needs the proper AC recharge equipment and gauges, otherwise they are better off having a pro do it. I'm sure others have had success in the past doing it themselves, but not me, ever.

what year is your 997.2? I would wonder why you need a recharge unless you use the system ALOT. is that the case?
I have used recharge cans with success in jaguar and Honda, havn't had to do the Porsche yet.
you can get cans w/out sealant at Walmart

You should be able to buy DuPont 134a w/o the added stuffs. I have not a need to recharge my 911 yet but for my other vehicle, the proper way is to use a vacuum pump and a set of cheap ac gauges.
The setup costs around $150-$200. Basically it's not worth it to DIY unless there is a need to recharge every year. Then something else need to get addressed first.

Thank you guys for the feedback. My car is 2009 which makes me quite surprised it needs an A/C recharge. But it spent most of her life parked in the garage in the previous life. I got her a year ago with 11K miles. May be I will try the dealership and their diagnostics.

The only correct answer. The charge level is very precise and you can easily do $$$ in damage by overcharging using those do-it-yourself recharge kits. Also, if it is low you probably have an issue somewhere. It's a sealed system and the refrigerant does not just evaporate over that short of a time.

I'd have an indie put some dye in the system and see if they can find the leak. If it doesn't appear easily, charge up the system and see how long it lasts. If it lasts more than a year, then I would go the DIY route and charge annually, if you mess it up, you mess it up. If it leaks within a month, you have a larger prob and I wouldn't mess around with DIY.

The key is to get the vacuum pump and AC gauges, that way you can tell how much R134a you put into the system (by evacuate the old R134a/vapor in the system first).

If your system needs freon you have a leak somewhere. Refrigerant is not a consumable. A precise amount is needed, also temperature and pressures are very important when charging a system. If you are not familiar with the process, have the tight tools....
just take it to a professional.

Wise choice. The AC system has a bunch of o rings that get lubricated by the refrigerant. If the AC is not used for a while, the O rings, or other components can develop a leak. So the theory that it sat in a garage for a while is possible.
I run my AC and heat at least once a month no matter what the outside temp is just to keep everything in check. Another reason: if the AC is down, I would rather get it looked at by a specialist in Feb when he is slow. Otherwise ill be car number 45 waiting to get an appointment in June.
I do the same thing on my house. Better to know your AC is out when the outside temp is 68 not 86.

i have vacuum pump, gauges and hose crimping tool. along with different a/c hose. spent a few hundred, but I made a complete system for a jag v12 and still have all the equipment. initial outlay is high but hey- I prefer to do my own work
