I assume that when you mentioned that the recharge only lasted for a month, that was until the a/c stopped working again? Usually a/c stops working when there is not enough pressure in the system due to it being low on refrigerant and given how long a non-leaking system normally lasts without a recharge, you've got a fairly substantial leak in a/c terms. ...

I got that exact same product! The hose didn't work very well. I ended up buying a separate hose for $15 or so, with brass fittings. Also, as Patrick said, a large amount of refrigerant solves a large refrigerant leak. And it won't solve it for long. So, I recommend either Go to the shop and get a leak test, and a refill if it's slow. Buy a quality hose ...

There is no difference between brands of R134A, unless there is some additive in it which will be stated on the label. Some include leak sealer, never use this, ever. The only real difference is Price.

They do work. I've used them often. If your low on freon, there may be a leak. However, if this is the case use a bottle of stop leak first or a bottle mixed with stop leak. It should seal up an value leakage. Replacing your AC unit is costly, most leaks can be fixed with a stop leak sealant unless the problem is serious. Save the hose you can reuse it. ...

This product solves one main problem(symptom), low freon. The issue with this is that most cases of a car that have low freon is caused by a leak somewhere in the system. If your car suddenly stopped blowing cold air, then this will most likely not fix your problem. Your problem is probably one of two things: A/C Compressor died Large freon leak I ...

Checkout the Auto AC board at AC Source There are some good people on there. Don's right. You do need to flush the old oil out of the system because they don't mix. Also it's difficult to flush the compressor so odds are it will not last i you don't replace it. The best thing to do is change the compressor out if its older at the same time, replacing all ...

Depends entirely where the leak is, and what's leaking. If it's on the high side it's going to leak faster when the AC is used. If it's on the low side it's going to leak slower when the AC is used. Since you are just trying to get by, and your getting rid of the vehicle soon you could top it off with the DIY AC charge kits sold at the local parts store ...

I don't need your end goal here, but in almost every vehicle I have worked on I have never had to remove the A/C compressor with the engine. They are designed to be disconnected from the engine and put to the side so you don't have to discharge the refrigerant from it. If you absolutely believe you need to remove or discharge the system, take it to a shop ...

I have done it before. I just replaced all the seals and o-rings, cleaned out all of the old oil and then refilled with r-134a. That's about it. I did it on an '86 Volvo 740 and it worked really well.
