I was talking to my HVAC guy and he gave me the option of the Trane system that uses the new refrigerant or American Standard, that uses the older refrigerant.

The Trane system has more safety checks, because the gas is slightly flammable and when it detects the gas/leak, it shuts down, and it has to be repaired versus the American Standard with the old refrigerant, where it might be topped off.


Soooo…. Would you go with the Trane and the new refrigerant or the American Standard and the old refrigerant? Pros and cons?
