      Questions5
      What is the SEER2 rating of the Midea MO1HE-H60B-2A?
      The Midea MO1HE-H60B-2A is rated at up to 17.5 SEER2 and 12.0 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 44 certified matchups SEER2 ranges from 15.2-17.5.
      Is the Midea MO1HE-H60B-2A good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 54,000 BTU/h at 5°F with a COP of 1.90, so it is still 1.9 times as efficient as electric resistance heat at that temperature.
      How much does the Midea MO1HE-H60B-2A cost to run per year?
      At its rated efficiency it costs about $1,396-$3,725 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,720 in Phoenix and $3,112 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 Midea MO1HE-H60B-2A?
      ENERGY STAR lists 44 certified combinations for this outdoor unit. The highest-rated ones use MAUSE-H60B-2A, MAAHE-H60B-CA-UC, MAAHE-H60B-CA.
      What refrigerant does the Midea MO1HE-H60B-2A 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.
