      A good fit if…

      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 50,000 BTU/h at 5°F.
      • It will heat most of the year - its HSPF2 beats 100% of central heat pumps.
      • You want steady temperatures and quiet running - the compressor varies its speed.

      Think twice if…

      • You want the newest refrigerant - it uses R-410A, which is being phased down.

      Questions5
      What is the SEER2 rating of the MDV MOE30U-48HFN1-M-[X]?
      The MDV MOE30U-48HFN1-M-[X] is rated at up to 17.0 SEER2 and 14.0 EER2 for cooling and up to 12.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 2 certified matchups SEER2 ranges from 15.6-17.0.
      Is the MDV MOE30U-48HFN1-M-[X] good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 50,000 BTU/h at 5°F with a COP of 2.02, so it is still 2.0 times as efficient as electric resistance heat at that temperature.
      How much does the MDV MOE30U-48HFN1-M-[X] cost to run per year?
      At its rated efficiency it costs about $1,154-$2,893 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,536 in Phoenix and $2,350 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 MOE30U-48HFN1-M-[X]?
      ENERGY STAR lists 2 certified combinations for this outdoor unit. The highest-rated ones use MTI-48HWFN1-M, MVC-48HWFN1-MQ3.
      What refrigerant does the MDV MOE30U-48HFN1-M-[X] use?
      It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and R-32.

      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.
