Coool A/C
I just finished overhauling my A/C system. New hoses, accumulator, compressor, orifice tube, and "O"rings. Flushed condenser, and evaporator coils. I would never have thought a closed system could get so grubby. Vacuumed it down,7oz. new PAG 46 oil, and 38oz. 134a. I got a vent temp. of 37deg. Man it's nice in there.

I know now why they charge so much to work on them. I started about 8:00 finished about 3:30. I flushed and flushed until I was satisfied they were clean and then blew the coils out with compressed air for 30 or 40 min. each. It was humid yesterday so I left the vacuum pump on there about an hour. There has to be a better way to flush one than using those little flush setups, I was constantly refilling that little cannister yesterday. Thanks for your reply.

They make a better flushing tool but unless you do a bunch of cars it is not worth the money. I built my own and will try to post some pics later.
I have also used a 3 gallon pump up garden sprayer to inject the flush (Brake cleaner)
.
Then blow it out good.
Glad to hear you evacuated it good. Some people will spend tons of time and money then not pull a vacuum. Even if you have to use one of the air operated Harbor Freight $10 pumps, it makes a BIG difference.
You should be proud of yourself for a job well done.
Best,
