How To A/c

[SVX_MY_BABY]

I could have sworn there was a How To in a simple o-ring replacement for the air conditioning. Can't find it. Was I dreaming? Was the o-ring fix for something else?

Yes, that one.

AC O-ring replacement takes an expert with the proper gauges and refrigeration recovery equipment.

Slightly more involved, but this should fix your problem.

I can do it without any gauges or refrigeration recovery equipment, but hey, that is just me

Of course you can do it without recovery equipment. That is only an environmental thing. You CANNOT do it correctly without gauges. You might be lucky most of the time trying to guess pressures, but sometime it is going to catch up with you.

And actually may have already if you have had compressors go bad.

PS: Maybe I should clarify. I am speaking only of R134 systems. The old freon R12 is very forgiving and no problem to self install except for vacuum pumping if necessary.

The "environmental thing" thing turned out to be just another of the liberal establishment jokes. The "hole in the ozone layer" is not the reason for ice melting at the poles. The "hole" has filled in at the north pole and the ice is melting. The hole at the south pole has not filled in and the ice there is not melting.

You CANNOT do it correctly without gauges.

I was raised in west Texas and as a toddler I was thought that " Can't", obviously derived from "CANNOT", was a cuss word. I think CANNOT always applied to east Texas folks!

You might be lucky most of the time trying to guess pressures, but sometime it is going to catch up with you.

After studying and teaching and doing refrigeration for almost 60 years, and not having problems with things I repair, luck is not in the equation. These air condition systems on our cars are unbelievably simple.

And actually may have already if you have had compressors go bad.

Not yet.. but a bad compressor after a couple of hundred of thousand miles could certainly be possible, but not possible to be related to how I maintain the system.

F-12 is what my systems all are and can't imagine why anyone would ever convert theirs to r134.

I've seen that done in a pick-up but that car is just classic. Great for running your power tools at the job site or for coolers and lights when tailgating.

Well, let's see, 94 and up came with R134. I would fully agree with your statement if everything were equal and the old freon was available at the prices it was prior to the switch. R134 is far less efficient and that fact is very obvious.

True, r-12 has gone up a bit!

Was $20.00 for 30 lb and now $2,000.00 for 30 lb and you can't buy it for that

Take care,

R-12 freon is readily available on ebay for an average of about $20 per 12 oz. can. Not as cheap as 'back in the day', but price and availability seem to have been pretty constant for about the last 5 years. Some sellers require proof of your EPA 609 certification to buy it, but there's really no enforcement. If you want a legitimate 609 certification, I got mine for about $20 online by taking a quick "open book" test, and it never expires.

There's no question that R-12 out-cools R134a!

I've never understood all the fuss about 134a refrigerant. Both of my cars use it and keep me quite comfortable here in the warm, humid south. After a few minutes the airflow becomes uncomfortably cold on my hands and I have to re-aim the vents. If there's a measurable, appreciable difference in cooling ability, as I gather there must be, it seems scarcely noticeable in real-world use.
