Questions
- What is the SEER2 rating of the AproDr AM6OG-48HFN1?
- The AproDr AM6OG-48HFN1 is rated at up to 21.3 SEER2 and 11.7 EER2 for cooling and up to 10.6 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 6 certified matchups SEER2 ranges from 20.4-21.3.
- Is the AproDr AM6OG-48HFN1 good for cold climates?
- Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 38,000 BTU/h at 5°F with a COP of 2.10, so it is still 2.1 times as efficient as electric resistance heat at that temperature.
- How much does the AproDr AM6OG-48HFN1 cost to run per year?
- At its rated efficiency it costs about $995-$2,797 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,245 in Phoenix and $2,351 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
- What refrigerant does the AproDr AM6OG-48HFN1 use?
- It uses R-454B.
