As of 2023, HVAC systems in the U.S. are no longer judged by the same efficiency standards as before. With the shift to SEER2 ratings, homeowners shopping for new heat pumps like the Goodman GLZS4BA3610 are facing a new set of labels, benchmarks, and performance expectations.

But what exactly is SEER2? How is it different from SEER? And how does the Goodman 15.2 SEER2 heat pump system stack up against older models?

Let’s break it down in plain terms, Mike Sanders–style.
