Hello,
First apologies for my english, but I think that we can very well understand.
I follow this forum (passive) and thank all the very useful posts in the field of refrigeration.

My entry in the World of refrigeration is a bit naive (easy money in a short time ) and everyone here know that it unfortunately does not work that way.

I work for myself and for my honor, I'm trying to do the job (installation of split system air conditioners) by the rules of the profession.

The problem is that the experts of the profession very rare to ask a banal question (the others are mostly accustomed and know just installing air conditioning, the only diagnosis is leaked gas
All my knowledge is "self taught" from the books and literature available.

I always want more (if I can), so I have a bunch of questions about the basic operations with the installation, commissioning and servicing of split air conditioners.

I ask what interests me and what I do, and someone with experience said to be made ​​better and easier way.

All issues are in some basic techniques of aircon, but there are always several ways

Thanks to all who are willing to help a novice.
Is there anyone willing to advise?
