Happens when the system is opened for service.

O.K.

One of the complaints (which is unfounded) about R410A is that it
operates under a much higher pressure than R22. When the system is off,
it's not uncommon for the pressure of a 410 system to be at around 160
PSI.

Explain how air can get INTO the system when it is "opened for
service".....



If I recall, I carry a vacuum pump for that very problem!

I know. I wasn't tryin' to give stormy a hard time. I was just trying to
knock down some of these "fears" about R410A.

Would I rather use R22? You betcha! But R410 is not as bad as everyone says
it is and whether they like it or not, it's here to stay!!!

I don't think there was anything wrong with R22 and they should have left it
alone. But politics are politics.....
