Natural Refrigerants Move From Niche Toward Default Specification
Carbon dioxide and hydrocarbon systems now account for roughly 23% of new condensing unit shipments, and the share climbs with every step of the phase-down schedule. What changed is not environmental preference but availability: high global warming potential refrigerants are being quota-restricted, and their service gas prices have risen enough to make replacement economics work on their own. Transcritical carbon dioxide dominates larger commercial installations while propane takes the smaller end where charge limits permit. Manufacturers who built service technician training around these platforms early are converting that investment into specification wins now.
Market Impact: Quota cuts run through 2036
