Questions
- What is the SEER2 rating of the Arcoaire D5CMHAH36EAK?
- The Arcoaire D5CMHAH36EAK is rated at up to 23.1 SEER2 and 13.1 EER2 for cooling and up to 10.7 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 36 certified matchups SEER2 ranges from 19.5-23.1.
- Is the Arcoaire D5CMHAH36EAK 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 2.00, so it is still 2.0 times as efficient as electric resistance heat at that temperature.
- How much does the Arcoaire D5CMHAH36EAK cost to run per year?
- At its rated efficiency it costs about $734-$2,093 a year in electricity in large U.S. cities, depending on climate and local rates - for example $923 in Phoenix and $1,763 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
- What refrigerant does the Arcoaire D5CMHAH36EAK use?
- It uses R-454B.
