It is best done at the beginning, when filling the system, fill one loop at a time then move on.

Also try to put an Auto air vent, microbubbler or air eliminator at or near a high point in the system.  ONLY WORKS ON PRESSURIZED SYSTEMS

BREAK out the Binford 9000 and let er rip. 

...by purging one line at a time you can see when most or all of the air is out of the line.  Plus with most loops being 300' or less its fairly easy to force enough water thru to get a large majority of the air out.
