      Questions5
      What is the SEER2 rating of the GREE GWH24AUDXH-D6DNA1A/O?
      The GREE GWH24AUDXH-D6DNA1A/O is rated at up to 24.0 SEER2 and 13.1 EER2 for cooling and up to 9.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the GREE GWH24AUDXH-D6DNA1A/O good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 22,000 BTU/h at 5°F with a COP of 1.75, so it is still 1.8 times as efficient as electric resistance heat at that temperature.
      How much does the GREE GWH24AUDXH-D6DNA1A/O cost to run per year?
      At its rated efficiency it costs about $437-$1,582 a year in electricity in large U.S. cities, depending on climate and local rates - for example $596 in Phoenix and $1,366 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 GREE GWH24AUDXH-D6DNA1A/O?
      ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses GWH24AUDXH-D6DN***/I.
      What refrigerant does the GREE GWH24AUDXH-D6DNA1A/O use?
      It uses R-32.

      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.
