How do you verify AHRI certification on a matched heatpump system?

keep seeing certification discussed at the brand level but AHRI matching seems much more speciffic than saying an entire manufacturer is simply "certified." The useful check is whether the exact indoor and outdoor combination appears in the relevant directory and what that listing actually verifies.

It also shouldnt be stretched into a blanket claim about reliability (ofc), installation quality, or every other model from the same brand. When youre checking a proposed heatpump combination what information do you match first against the AHRI listing?
