      A good fit if…

      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 52,000 BTU/h at 5°F.
      • You want steady temperatures and quiet running - the compressor varies its speed.

      Think twice if…

      • Cooling cost matters most - its SEER2 is below average for central heat pumps.

      Questions5
      What is the SEER2 rating of the Elios ESHMA60R2AN1?
      The Elios ESHMA60R2AN1 is rated at up to 16.0 SEER2 and 10.0 EER2 for cooling and up to 9.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 2 certified matchups SEER2 ranges from 15.2-16.0.
      Is the Elios ESHMA60R2AN1 good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 52,000 BTU/h at 5°F with a COP of 1.83, so it is still 1.8 times as efficient as electric resistance heat at that temperature.
      How much does the Elios ESHMA60R2AN1 cost to run per year?
      At its rated efficiency it costs about $1,584-$4,103 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,934 in Phoenix and $3,414 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 Elios ESHMA60R2AN1?
      ENERGY STAR lists 2 certified combinations for this outdoor unit. The highest-rated ones use EAHMA60R4AS1, GCHMA60RDAS1.
      What refrigerant does the Elios ESHMA60R2AN1 use?
      It uses R-454B.

      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.
