This seems like it’s Lennox advertising to me. Other brands achieve similar or better results. I had to get a new hvac system installed suddenly last April. The unit we went with appear to have the same or better ratings: COOLING SEER2 Up to 23, Cooling EER2 Up to 14, HEATING HSPF2 Up to 10.5, operable as cold as -22°F.
