Motor-start caps and an unrelated question
Mastercarpentry

My biggest customer lamented to me yesterday that service calls for compressor motor-start capacitors were killing him. The ones which fail and all the replacements he can get are made in China and don't last as long as the older American-made ones did. So does anyone have a source for these that he won't need to be changing out every 18 to 24 months?

My second question relates to my "new" van, a 91 E 350 that uses R-12. It seems to need a refrigerant top-up and of course you can't get R-12 anymore. So is there an available refrigerant that is compatible with R-12? Probably wouldn't amount to more than 15% of the total charge. If it helped any at all that would be good enough, it's cool now but not cold. Got a bargain deal- $1K, this thing is in nearly new condition with only 132K miles on it. I think it was garage-stored most of it's years. Sometimes ya gets lucky :cool:

Can't help you with the caps.

For the AC, have you thought about cans of air duster from the office supply?

USA made a/c capacitors can still be found. Tell your friend to look harder.

Question 1- try here http://www.airstarsolutions.com/Pages/USACapacitors.aspx

Question 2- you can have a conversion unit installed and then you can use the never refrigerants. I had it done on my 92 F250.

Thanks for the Cap link JL, you just made me a 'hero' :D And Spruce, I'm going to try the duster ;) The system cools OK now but not great, and as cheap as I (am along with not really needing A/C) I won't pay for a conversion kit. I've only had 2 vehicles with working A/C in my life anyhow but since this one is 'almost there' I figured it's worth a few bucks to try.

As always the vast wide-ranging knowledge you guys is awesome!

I watched another video over the weekend from the guy where I got the idea from. I was wondering how he got the contents of the can into the system when the can didn't have the usual refrigerant top that the automotive cans do. Well, yesterday he showed the device he used, which basically are vice grips that go around the can with a pierce point in them. The gauges connect to the pliers and the system. I don't remember what he called them, but they were in this video if you need such a beast.

He shows can pliers at time index 10:30, and also tells you how much he put into a completely empty system.
