      Questions6
      What is the SEER2 rating of the GREE GWH09AGCXD-D6DNA4D/O?
      The GREE GWH09AGCXD-D6DNA4D/O is rated at up to 26.0 SEER2 and 15.0 EER2 for cooling and up to 10.4 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 8 certified matchups SEER2 ranges from 22.0-26.0.
      Is the GREE GWH09AGCXD-D6DNA4D/O good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 10,000 BTU/h at 5°F with a COP of 2.15, so it is still 2.2 times as efficient as electric resistance heat at that temperature.
      How much does the GREE GWH09AGCXD-D6DNA4D/O cost to run per year?
      At its rated efficiency it costs about $167-$600 a year in electricity in large U.S. cities, depending on climate and local rates - for example $227 in Phoenix and $517 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the GREE GWH09AGCXD-D6DNA4D/O the same as the GREE GWH09AUCXD-D6DNA1C/O?
      Yes, as far as the certified ratings go. ENERGY STAR lists both model numbers with identical efficiency, capacity and matchups, which means the same outdoor unit sold under a different brand or with a minor variant code (voltage, colour or region). The full list is on this page.
      Which indoor units work with the GREE GWH09AGCXD-D6DNA4D/O?
      ENERGY STAR lists 8 certified combinations for this outdoor unit. The highest-rated ones use GWH09AGCXD-D6DN***/I, GWH09AUCXD-D6DN***/I, GWH09AUCXD-D6DNA2D/I.
      What refrigerant does the GREE GWH09AGCXD-D6DNA4D/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.
