1992 Silverado, 305...150,000 miles. Switched on AC the other day, and it did not get cold. The "AC" led was blinking, I assume indicating it was in distress of some sort. Ive had the truck 4 years, cold AC every summer, but now I guess thats out the window. Anyway...I started smelling freon in the cab and when I opened the hood, I again smelled it. You cant miss that smell, it stinks bad. Besides repairing, besides refilling, what can I do stop the the smell? It cant be good to breath this stuff. Truck got "totaled" by ins. compnay last week, but runs and drives, so its hardly worth putting any real bucks into it. Thanks.

Fix it. Leave it. It is kind of rough that you don't feel it is worth the effort to keep it running but don't whine. Add some freon and see if it leaks again. It it does, either put another can in or ignore it and hope the pump don't seize up.

Is it an A/C belt that's slipping that's generating the smell?

R134a DOES have a smell. I smelled it a lot when I was fixing my Explorer's AC. If you smell it inside the cab, my guess would be a bad evaporator.

The odor is so light that usually, and especially in older equipment, the odor of whatever the refrigerant is blowing past will mask the smell of the refrigerant itself. It by no means stinks. Stinky usually means organics getting too hot, like rubber belts or clutches.

You were smelling the odor that Pag oil has.

When my 1999 Dodge Grand Caravan ended up with a leaking evaporator (these things were almost guaranteed to leak...thank you Chrysler), the smell from the vents reminded me of the smell of a box of band-aids...really.

I never noted a smell of R12 or R123a, either.
I don't think they have a smell.

So you have a smell from a totaled car?
Coolant or oil on the hot exhaust is more likely.
And on that totaled car, don't you think that you may have more that one problem?

DING DING DING. r134a has no smell. Its the pag oil you're smelling. And yes likely issue at the evaporator/connections to. AC systems have pressure switches, if you have a leak once pressure drops below certain amount it will force compressor clutch from engaging to avoid damage to compressor.

R134a has no smell? A slight smell, yes; odorless, no. Here are two MSDS sheets from DuPont and National Refrigerants.
