When I worked in auto parts I sold it . Great stuff. I worked there for 12 years
Four Seasons A/C components

Thanks to all you guys... I appreciate it. From what I could ascertain, they have a plant in Texas as Steve pointed out.
Jack, I redid the ENTIRE AC system on my Sunfire. I purchased all from RockAuto and pretty much most of it was 4 Seasons. Good stuff, but as was pointed out, sourced from all over. That said, I am very satisfied by the brand. Their compressors were all remanufactured, so I went with Delphi for a new one. Now I'm blowing 35º below ambient. Beware that for any compressor warranty to be valid, you must show that the component was professionally installed and a flush was performed.
Hi Mark,
Yes, I noticed most of the A/C parts from RockAuto were the Four Seasons brand. They do offer "new" compressors, besides reman'd units. I refuse to go with a reman.
Where were you able to obtain a Delphi compressor?
I was actually going to install the new components myself and have a local shop charge the system. The system won't have to be flushed because it will all be new...from condenser to evaporator. Would I have to show proof of "professional" installation after purchasing the parts, or only when, or if a problem occurs?
Jack, RockAuto offered it, and still does. Sunfire, not Bonnewagon, R-134. I removed the dash, seats, console, everything but the engine to get that system in. $500 in parts. And since after digging down that much I was staring at the heater core, I did that too just as insurance. For the wagon I bought a used reman R-12 unit from a guy on here for $50 and it worked very well, still nice and cold. I used ES-12, an R-12 replacement that is compatible with the old mineral oil, so no flush needed. But the compressor warranty specified a formal bill from a certified AC establishment with proof of a flush. Not sure how a home job figures in but as far as I read, I disqualified myself by doing the work. Since you live in sunny Florida, I would advise you to get a set of manifold gauges, a vacuum pump, and do it all yourself. For what they charge for a fill these days,, you could buy the tools. I even had good results with a cheapo Harbor Freight vacuum thingie that used compressed air to produce vacuum. At 29" vacuum, water boils, and that gets all the moisture out of the system, guaranteeing good performance. I was so happy with the results I invested in a real vacuum pump and now I do all my family's AC. (What an idiot I am!) Are you going with R-12, R-134, or the new stuff?
Mark,
At one point I thought of investing in a vacuum pump and manifold/ gauge setup, but I don't know how much A/C work I'll be doing after this. I'm not getting any younger... but I guess, never say never.
I will be going with 134A. I'll also be replacing the condenser with a new parallel flow unit, new evaporator, heater core (while I'm in there), besides manifold hoses, compressor, drier, orifice tube, etc. So it will be a completely new system.

Well, replacing everything is a chore and I'm with you on that. This old age sh*t is for the birds. 
But servicing a system is the easy part. Aside from no leaks, the main thing is getting the moisture out and filling with the exact amount of freon required. Do not ignore this! R-134 systems use a specific amount and over/under filling is bad for performance. I use 30lb tanks because it is cheaper to buy that way. Then I bought a cheap digital postal scale on Epay for like $18 and I use it to add the exact amount listed on the underhood sticker. Since you are retrofitting to R-134 I am not sure what amount you would use but while researching on the HVAC sites I found a formula/percentage for R-12 to R-134. That would be your starting point and then you would use the gauges to decide if you were getting the most from the system.

It's a chore, no doubt, but I'd like to make it as reliable as I can. I was hoping I would be able to do it under a certain budget.
If I'm not mistaken, it allegedly uses lesser amount of 134A than R-12.
I think it was something like 90%...don't quote me on that. You obviously had more experience working on this stuff than I have. I'm just learning more about it now. But I suppose it wouldn't kill me to learn something new at my advanced age...😕

Don't feel bad. In my ignorance I used to yank and scrap any AC that didn't work. And on my POS cars, it usually didn't. So finally about 10 years ago I began reading, and learning, and acquiring tools, and now I'm kicking myself in the *ss for not fixing all those simple AC systems. Oh well, live and learn.....
