What this page verifies
This page reports fields present in the packaged EPA / ENERGY STAR record. A matched heat-pump row keeps its outdoor and indoor identifiers together. The page does not infer cabinet width, filter size, replacement compatibility or warranty status unless a later manufacturer-document layer verifies those fields.
