      Questions5
      What is the SEER2 rating of the MRCOOL AEPL**MHV23S0932B1A?
      The MRCOOL AEPL**MHV23S0932B1A is rated at up to 23.0 SEER2 and 12.0 EER2 for cooling and up to 10.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the MRCOOL AEPL**MHV23S0932B1A good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 8,000 BTU/h at 5°F with a COP of 1.80, so it is still 1.8 times as efficient as electric resistance heat at that temperature.
      How much does the MRCOOL AEPL**MHV23S0932B1A cost to run per year?
      At its rated efficiency it costs about $185-$554 a year in electricity in large U.S. cities, depending on climate and local rates - for example $236 in Phoenix and $469 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 MRCOOL AEPL**MHV23S0932B1A?
      ENERGY STAR lists 2 certified combinations for this outdoor unit. The highest-rated ones use AEPL**AWM23E0932B1A, IWAE AEPL**AWM23E0932B1A.
      What refrigerant does the MRCOOL AEPL**MHV23S0932B1A use?

      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.
