An HVAC subcontractor I used lost track of the start-up procedure on one of the systems. His techs just forgot that the one of the four condensers was never purged of the nitrous and charged with 410. He basically just started it up. The client used it for about a week off and on and since they don't live in this area of the apt. Too often, didn't notice it wasn't blowing cool air. The techs that came to service it said it was frozen. Than they old me what I just said above.

So the question is is this equipment damaged now. It is working but this guy would service it. He only does for the first year.
