Don't listen to these guyz.......I don't know ANY AC shops that don't install filters in the lines after a system fails. You just can't get all the trash out unless you replace EVERYTHING. You do as you please but I've been doing AC systems for over 40 years, I'd do like I suggested. Good Luck.

Im just going to drop it off and have someone deal with it as i dont have the time. I replaced alot of stuff myself last year. Yes i added oil to the compressor and the orphice was clean at that time and i replaced it any ways as well as the dryer. Again its a pressure SENSOR not switch so it actively reads psi and the computer turns the compressor off when the psi is low.
when you install an inline filter with the purpose of catching trash you just started making a second orifice tube in the system that then starts restricting flow causing a pressure drop. even if the inline filter is completely clean, in an orifice tube system it will still act as a small restriction causing a pressure drop and reduce ac cooling performance. you want the pressure drop happening at the orifice tube.
uh wait, there's already a filter in the orifice tube
sounds like you don't know any honest/knowledgeable AC shops

The additional in-line filter is there while the system is being cleaned/flushed....not permanently. The orifice tube is awfully small to pick up all that much material and not be ruined. After the in-line has cleaned the system up, it's up to the orifice tube to pick up minor debris. If the compressor failed and sent out metal shavings/slivers those are difficult to get out of the condenser. Sounds like you had a refrigerant leak. If you went with a used or reman compressor you might only get 1 year of life. A quality new compressor costs a bit more, but that's one less time you have to go into the system. As I recall Delphi, Denso are two decent brands. I put a Delphi in my '99 2 years ago. Check the HP line for leaks as well, especially around the HP sensor and the charging "valve." The HP line is solid metal. It's the LP line that has metal fittings crimped on a rubber hose. A cheap or used receiver/drier could develop cracks on the welds.

As 1 FMF stated there are all kinds of different control systems. Although the fundamentals of an A/C refrigerant system are pretty much the same.
I myself would never put any extra filter in the system.

Actually its more like 45 years working on ac systems. There is nothing I can add to help you GUYZ.....you should never post info on systems you have no idea of how they operate. All it does is confuse things more. Sometimes I think you GUYZ are a bit quick to post just to post.
OP good luck but trust me if you don't REPLACE EVERYTHING or use a filter it will probably fail again. There is another option you have but its a real money waster, as the debris collects on the inlet screen at the orifice tube pull it out and clean it off. But its so small it will block quickly. Probably what is wrong with it now. Here is info on a system filter http://www.autoacsystems.com/fasttrack/filters.html

lol don't test me jr........the accumulator AND some use a noise suppressor . Lets just end this ok? I do huge systems including reengineering updating and retrofits.
I'm also a electrical systems engineer AND a complete whack job, you wouldn't want to eff with me trust me. I NEVER LIE EVER!

The part missing in "typical A/C system schematic" is a filter-drier unit. One of either two types. An accumulator (which you mentioned) or a receiver-drier. Yes they are different.
Hmmm. I wonder why they would leave that out? Oh yea, that's right. Scam.
Alright RockinWs6. I'm out.

The accumulator is the "filter dryer" if you want to call it <buts not really> in these systems. They don't use such a thing in MODERN car ac systems. this isn't the 60's when they actually used a filter dryer.
An Accumulator is a Receiver dryer. It is not a filter dryer. Shall we continue GRASSHOPPER?

An accumulator is NOT a receiver-drier! Basically they do the same job, like a filter drier, but they are not the same.
