R-410A vs. Opteon XL41 on Platinum-Series Equipment

Comparing American Standard to Trane Model Numbers
Because the two brands share engineering and manufacturing, a technician familiar with Trane's model prefixes can often map directly to the equivalent American Standard prefix useful when cross-referencing parts or refrigerant type between the two brands.
Legacy R-22 American Standard Systems
Older American Standard residential systems built before the mid-2010s commonly still run R-22 and depend on reclaimed supply for continued service.
