      A good fit if…

      • You want low cooling bills - its SEER2 beats 79% of central heat pumps.
      • You want steady temperatures and quiet running - the compressor varies its speed.
      • You want a choice of indoor units - 35 certified pairings.

      Think twice if…

      • You often see nights below 0°F - it is not cold-climate certified.

      Questions5
      What is the SEER2 rating of the Midea MO1BE-H30B-2A?
      The Midea MO1BE-H30B-2A is rated at up to 18.6 SEER2 and 11.0 EER2 for cooling and up to 8.7 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 35 certified matchups SEER2 ranges from 15.2-18.6.
      Is the Midea MO1BE-H30B-2A good for cold climates?
      It is not cold-climate certified: none of its matchups meet the ENERGY STAR cold-climate criteria (a COP of at least 1.75 at 5°F among other limits). In places with frequent sub-zero nights, pick a cold-climate 2.5-ton model.
      How much does the Midea MO1BE-H30B-2A cost to run per year?
      At its rated efficiency it costs about $734-$2,077 a year in electricity in large U.S. cities, depending on climate and local rates - for example $921 in Phoenix and $1,748 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 MO1BE-H30B-2A?
      ENERGY STAR lists 35 certified combinations for this outdoor unit. The highest-rated ones use MAWHE-H30B-2A, MAAHE-H36B-CA-UC, MAAHE-H36B-CA.
      What refrigerant does the Midea MO1BE-H30B-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.
