      A good fit if…

      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 40,500 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 mini-splits.

      Questions5
      What is the SEER2 rating of the MDV MOE30-48HFN10-M2?
      The MDV MOE30-48HFN10-M2 is rated at up to 19.9 SEER2 and 9.5 EER2 for cooling and up to 10.2 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 8 certified matchups SEER2 ranges from 17.1-19.9.
      Is the MDV MOE30-48HFN10-M2 good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 40,500 BTU/h at 5°F with a COP of 2.11, so it is still 2.1 times as efficient as electric resistance heat at that temperature.
      How much does the MDV MOE30-48HFN10-M2 cost to run per year?
      At its rated efficiency it costs about $1,134-$3,084 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,405 in Phoenix and $2,582 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 MDV MOE30-48HFN10-M2?
      ENERGY STAR lists 8 certified combinations for this outdoor unit. The highest-rated ones use MUE-48HRFN10-M2, MUE-48HRFN10-M2-D, MCD-48HRFN10-M2.
      What refrigerant does the MDV MOE30-48HFN10-M2 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.
