HELLO, Anyone knows where to get standard HVAC legends?

You must be a newbie.Take a look in the CAD/BIM Blocks section of this website and search on the letters HVAC (bet you didn't see that one coming).  I know for sure someone has posted a library of dynamic blocks for HVAC and I'm pretty sure there has to be other similar content either separate or as part of a typical HVAC layout.  Seek and ye shall find.

Already go through them, i need standard one.

What's a "standard" one?  You mean regular blocks as opposed to dynamic blocks?

The One Issued By Internasional Standard Assosiation, Maybe....

I doubt you'll find anything like that.
