Re: A/C problem
it's against the law to knowly charge a leaking a/c system and leave the charge
in if the leak is not repaired
don't try to use a can with sealer it react to o2 to seal the leak so any o2 in
the system and it's sealed off but good requiring coils and hose replacement

Re: A/C problem
You don't really "know" that a system is leaking until you find the leak.
Your typical shade-tree mechanic may not have the reasoning ability to
connect chronic low pressure with a leak.
All seriousness aside, I fully agree but people are going to do, what they
are going to do, and why do they sell those twelve-ounce cans of freon, that
come with their own recharge hose, anyway?
It took me two cans of sealer/leak detector to find the leak in my Suburban,
after two "certified" mechanics said they had it fixed, and seriously
overcharged me for six pounds of freon. The experience led me to buy a
vacuum pump and gauges, and almost to come out of retirement. The sealer,
leak detector, and oil were all leaking down the drain from the rear air,
onto the ground. ;o)

Re: A/C problem
You don't really "know" that a system is leaking until you find the leak.
Your typical shade-tree mechanic may not have the reasoning ability to
connect chronic low pressure with a leak.
All seriousness aside, I fully agree but people are going to do, what they
are going to do, and why do they sell those twelve-ounce cans of freon, that
come with their own recharge hose, anyway?
It took me two cans of sealer/leak detector to find the leak in my Suburban,
after two "certified" mechanics said they had it fixed, and seriously
overcharged me for six pounds of freon. The experience led me to buy a
vacuum pump and gauges, and almost to come out of retirement. The sealer,
leak detector, and oil were all leaking down the drain from the rear air,
onto the ground. ;o)
