A/C questions

'90 2.3 LX. My A/C system has a leak. I thought it was the compressor but after reading this I may be wrong. I didn't know you could put stop leak in a A/C system.

I should NOT put stop leak in & recharge with R134.
I SHOULD convert it to R134 (install retro kit), have system purged & charge with R134.

I only need the A/C for this year. The car is gone after that. I don't want to pump a lot of $$$ into the A/C system but I do need it for MD summer!

Yes.... And No. I did my conversion 2 years ago... by "donating" my extra R12 to the local A/c shop, then putting in some stopleak & oil and i charged the system with 134A. It has blown Ice cold since then with only a slight (about 6 oz) recharge last summer. You are correct though, to do it correctly you need to replace the lines and O rings, but using the cheap 29.95 Walmart kit i have enjoyed ice cold A/C with virtually No investment compared to the cost of a "real" conversion. You dont need EPA licenses to mess with R134 and its Really cheap compared to fixing it the "right" way. One of these days i will put new lines and Evaporator on. But why fix it if it works?

What if my air is slowly getting warmer every day?

last week at this time it got so cold i would turn it off, 3 days later it got slightly warmer
and now it barley gets cold, i would call it luke warm air.
 
I do commercial refrigeraion , c-stores etc. I read of numerous fines for not fixing leak. Look out for some "drop-in" freon. The repair tech that does our sevice trucks says some of them is almost pure propane. I would not want couple pounds of propane under my hood under high pressure. If not r-134a or r-12 I wouln't use it. Be safe.
