Yah I was really thinking about just taking to to get it emptied out, then in my own time replace the parts and take it to get it oiled/charged. I just didn't want to pay for that part when I'm capable of doing it myself.

609 certified just means you remembered to say I won't vent CFCs to the atmosphere when asked.

It has no technical qualification implications.

It most certainly qualifies you to service other peoples systems. Without it you could be subject to hefty fines. And its not just about not venting to atmosphere (though you could be fined $25k+ if caught doing so).

You should go to EPA.gov and read about it. All it lets you do is buy CFCs like r-12

EDIT: $19.99 and an open book on-line test and you too could be EPA 609 certified. And to pass the test, repeat after me: "I will not vent refrigerant to the atmosphere".

RE-EDIT It went down in price.

Section 609 certifies you to work on other peoples A/C systems. It has very little bearing on technical knowledge of A/C systems. And technically, only one person in a shop has to be 609 certified.


I agree, though, that giving Jimmy a can of Autozone refrigerant (SEALANT! ICK!!) is a recipe for environmental, financial (on Jimmy's part), and automotive disaster. You're not going to get the correct charge by shaking a can until a cheap gauge set reads a certain PSI. You need an accurate, digital scale.

Long story short: You might save hundreds doing the work yourself or you might **** your A/C system up even more and cost yourself a LOT more money than just paying a pro in the first place.

609 certifies you have had training to handle refrigerant. It doesn't
say you know squat about air conditioning.

If only one person is certified, than only that person can work on the system. It's not a shop certification. Its a per person certification. Working on someone elses system for profit without the certification is a violation of Federal law.

I'm getting a little 'chirp' from the A/C fan clutch every time the clutch engages.

Anyone know much about this? Can I replace just the fan clutch on the compressor?
(or throw some grease in there somewhere?)

Probably the belt is a little loose. Per the manual to have a used belt deflect 3/10 of an inch when you put 22 lbs force on it is incredibly tight.

^Cool, i'll check that out.
I had recently taken everything off to pull the motor so I may have left it a little loose.

Just ordered a condensor w/dryer and expansion valve from here: http://www.rockauto.com/catalog/raframecatalog.php
Got a high pressure hose from a member here and going to follow the DIY when it all arrives.

Is the hose bad? Mine it was just the o-ring. That fitting sees a lot of heat and vibration.

If you get a used hose you want new o-rings anyway. lubricate them with PAG100 oil. belive it or not the amount in the manual for the condeser is 1/4 ounce???

Replaced the O-ring on the high pressure hose at the compressor still had a leak. After cleaning all of the lines so leaks would show up easier I noticed dots of AC oil (and UV dye) equa-distant apart along the rubber hose eventually dripping down... I assumed the hose was bad

Received some parts still waiting on the rest to start the project.

I'm replacing:

Condenser and dryer
Expansion valve
high pressure hose (have spare low pressure)
and Fram ventilation filter (while i'm in there behind the glove box)

I'm thinking of getting the system pumped and recharged by a professional instead of buying a pump (no one rents them around here), manifold tubes, and recharge can. Depending on what they will charge $$$... no pun intended

Quick question. If your AC is cold for 1-5 minutes then goes warmer and warmer to the point of not being AC at all is that a sign of bad condenser/dryer? I have no leaks at all it was tested for leaks. Should I replace the condenser/dryer and expansion valve? Or could it be the compressor? I am getting the system discharged and doing the other work myself and then taking it back for the recharge. Should I replace everything or just the condenser/dryer and expansion valve?

When it hasn't been cooling for a while and you park the car does it leave a big puddle of water under it (evaporator frozen up)?

Do you have gauges to see what the pressures are when it is not cooling (expansion valve sticking)?

I have no gauges. Yeah I think it did leave more water under the car than a normal AC would. I'm not 100% positive as I gave up on AC about 3 years ago. I was just getting back to it and thinking about fixing it. If it is freezing up and there are no leaks what is the next step?

Looking at your post again 1-5 minutes would be pretty quick to form ice on the evaporator but there is a TSB about that: Look herehttp://forums.nasioc.com/forums/show...orator+ice+tsb

You could be just low on r-134. You can look at the pressures to see if the evaporator is starved.

Unfortunately the only way to fill it is to start from zero either by removing all the r-134 or if it all leaked out and you pulled it to vacuum.

You could do a search for expansion valve and see if your symptoms match

If you got some gauges and a thermometer you could ask a question over at this palce. http://www.autoacforum.com/categories.cfm?catid=2 The guys that run it know this stuff.

How's AC system in you guys' Subaru? Do you really have to crank up the A/C to get the cold air going? Also, RPM / vacuum shifts significantly to the point it's annoying to drive at times.

That's my observation on my 02 WRX after I did work to replace expansion valve and condenser/drier.

No problems here on my 02, original compressor and almost 150k. Just had to replace the top compressor o-ring. I get a pretty steady 40 degrees out of the center vent whether I'm idling in traffic, or on the highway.

In the extreme heat of summer my AC seems to get heat soaked. If I am moving it works great but if I get stuck in traffic it does not seem to work so well.

2Fast4U1DAY must work for Oshlapa. he's so worried about being compliant that he forgot that the government works for him. not the other way around.
subject to heft fines just means 'we can legally tax you more money'. and its not illegal unless you get caught. I dont need them one bit, but they sure as hell need us. the EPA is a joke. any government program is a joke.

i'll change my stance on the above when this statement proves to be false: 'If throwing money at people worked, then it would have worked by now.'

MY ac went out.. The clutch on the compressor messed up. You can turn it but then it gets hard to turn then easy to turn then impossible to turn.

1,100 to fix.. Getting done now at the dealership. Replacing the compressor and other parts as well
