Sources. Performance ratings from the AHRI Directory (cited by reference number 216772358; not a verbatim mirror) and ENERGY STAR certification data. Operating-cost ($/MMBtu), savings and percentile figures are computed by Verified HVAC Data from published ratings and EIA U.S. average energy prices — see our methodology. Refrigerant GWP is the IPCC value for that refrigerant. We publish no star ratings and take no payment for placement. "Not published" means the source registry doesn't disclose it — we never fill a spec with a guess.
