Questions
- What is the SEER2 rating of the GREE GWH12AGCXD-D6DNA4D/O?
- The GREE GWH12AGCXD-D6DNA4D/O is rated at up to 24.5 SEER2 and 13.0 EER2 for cooling and up to 9.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 8 certified matchups SEER2 ranges from 21.0-24.5.
- Is the GREE GWH12AGCXD-D6DNA4D/O good for cold climates?
- Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 11,000 BTU/h at 5°F with a COP of 1.95, so it is still 2.0 times as efficient as electric resistance heat at that temperature.
- How much does the GREE GWH12AGCXD-D6DNA4D/O cost to run per year?
- At its rated efficiency it costs about $232-$763 a year in electricity in large U.S. cities, depending on climate and local rates - for example $306 in Phoenix and $652 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
- Is the GREE GWH12AGCXD-D6DNA4D/O the same as the AireForce DXH12PSK3IH?
- 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 GWH12AGCXD-D6DNA4D/O?
- ENERGY STAR lists 8 certified combinations for this outdoor unit. The highest-rated ones use GWH12AGCXD-D6DN***/I, GWH12AUCXD-D6DN***/I, GWH12AUCXD-D6DNA2D/I.
- What refrigerant does the GREE GWH12AGCXD-D6DNA4D/O use?
- It uses R-32.
