York's YLAA Chiller Platform and Opteon XL41
York was one of the first major manufacturers to get a large air-cooled chiller platform specifically approved for R-454B.
R-410A vs. Opteon XL41 on YLAA Chillers
Newer YLAA units built for the A2L generation use Opteon XL41, while earlier production runs remain on standard R-410A. Confirming the specific unit's approved refrigerant against York's chiller documentation is essential before a recharge, since chiller-scale systems hold far more refrigerant charge than a residential unit.
Residential and Light-Commercial York Systems
Outside the chiller platform, most York residential and light-commercial split systems still run standard R-410A, following the same broader industry timeline as other major brands.
Legacy R-22 York Equipment
Older York commercial and residential systems built before the R-22 phase-out depend on reclaimed R-22 supply for continued service, since virgin production has ended.
