      Questions5
      What is the SEER2 rating of the KERR A-KHP06SA-1?
      The KERR A-KHP06SA-1 is rated at up to 25.5 SEER2 and 18.0 EER2 for cooling and up to 14.8 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 3 certified matchups SEER2 ranges from 22.0-25.5.
      Is the KERR A-KHP06SA-1 good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 8,100 BTU/h at 5°F with a COP of 2.40, so it is still 2.4 times as efficient as electric resistance heat at that temperature.
      How much does the KERR A-KHP06SA-1 cost to run per year?
      At its rated efficiency it costs about $120-$317 a year in electricity in large U.S. cities, depending on climate and local rates - for example $147 in Phoenix and $264 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Which indoor units work with the KERR A-KHP06SA-1?
      ENERGY STAR lists 3 certified combinations for this outdoor unit. The highest-rated ones use Kerr B-KHP06SA-1, Kerr B-KHP061A-1, Kerr B-KHP121A-1.
      What refrigerant does the KERR A-KHP06SA-1 use?
      It uses R-454B.

      Estimates use the unit's rated SEER2 and HSPF2, full-load hours derived from NOAA 1991-2020 degree days, average residential electricity prices from the U.S. EIA (12 months to July 2026) and fuel prices from EIA (2025 for natural gas, week of 2026-10-05 for propane and heating oil). Very cold days that need backup heat are not modelled. Federal minimum for comparison: 14.3 SEER2 / 7.5 HSPF2.
