  • Certified figures
  • Median
Each dot is one set of certified figures; models with the same figures share a dot. Right is more efficient over a cooling season; up is more efficient over a heating season.
Most efficient heat pumps, ranked by seasonal cooling efficiency (SEER2), then heating efficiency (HSPF2)
