Air COnditioner Gurus

It annoys me seeing people still trying to attempt air-conditioning without a license after all the rubbish people that deal with it have to go through. But I suppose they may not know since they arent actualy in the industrie

relax, read above. I have a licensed guy doing the work.

At the risk of hijacking my own thread, have you ever changed a tap washer? done any mechanical work on any vehicle other than your own? changed a light switch or a power point? these all put you in the same boat as doing ac/fridge work without a license. which I am not. I don't have the skills and I don't have the gear. if you have nothing constructive/helpful to add then please, don't say anything at all.

yes I have changed a tap washer but no I've never plumbed any of my house I've built/bought. and no I havent done any major mechanical work on my car I support my local mechanical workshop by letting them do my work on my own car the only time I have done any major mechanical work on my vehicle is when I built my 75 series with a v8 diesel in it because I couldnt find anyone were I live capable Of doing the work. And I would not in a million years touch 240v a/c youre talking about something that could kill imagine if you did something wrong and youre son or daughter were to get shocked and die from some sub standard faulty work that you did. I pay money to be licensed I pay 1000's a year for training me and my staff.

back to the topic,
i remember flushing a system with Argon.?

was flushed with nitrogen. any dry, inert gas should be ok?

Nitrogen is not an inert gas.

there's always one

no nitrogen is not inert in the purest sense of the word, but for the sake of flushing and drying a refrigeration system, it is far less reactive than oxygen and much dryer than water and those are the things that do the damage and much cheaper than argon and it is what refrigeration mechanics use for such purposes.

thanks for another worthless addition to this thread.

That wasn't meant to be a smartarse comment.

I was more refering to fact that nitrogen is not a member of the Inert Gases (or Noble Gases) in Group 0 of the Periodic Table, rather than the word 'inert' as a description of nitrogen.
You aren't the only one reading this thread and someone else may have been confused and/or misled by the comment.
But, yes, nitrogen is 'almost completely inert'.

Maybe I should have been more descriptive in my post...
