To address point number 1:

Yes, that is code in the four states in New England that I have done
repair work in...

Not in the NEC. Doubtful 4 New England states are insane.


To address point number 2:

Nothing may be vented to the atmosphere when doing any sort
of HVAC work in Massachusetts or Rhode Island... Nothing...
So if Nitrogen is charged in a coil during shipment to prevent
damage, it must be recovered prior to the pressure test and
the refrigerant being charged into the system...

Next fallacy ?

Maybe that explains a lot of the NY attitude -- too many
pollutants in the air...


Good point. Nitrogen is one of the serious air pollutants and nothing is
being done about it. Your capturing it is a step in the right direction.

You NYers need to listen to Evan. Capture the nitrogen before it is too
late!!!!


Ummmm, WTF? That's as stupid as claiming CO2 as a pollutant or
Dihydrogen monoxide (DHMO) being the most dangerous substance
around. ^_^

TDD
