      A good fit if…

      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 41,000 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 central heat pumps.

      Questions5
      What is the SEER2 rating of the MRCOOL MVP-48-HP-C-230A00-O?
      The MRCOOL MVP-48-HP-C-230A00-O is rated at up to 16.0 SEER2 and 10.0 EER2 for cooling and up to 9.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 8 certified matchups SEER2 ranges from 15.2-16.0.
      Is the MRCOOL MVP-48-HP-C-230A00-O good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 41,000 BTU/h at 5°F with a COP of 1.85, so it is still 1.9 times as efficient as electric resistance heat at that temperature.
      How much does the MRCOOL MVP-48-HP-C-230A00-O cost to run per year?
      At its rated efficiency it costs about $1,318-$3,287 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,592 in Phoenix and $2,721 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 MVP-48-HP-C-230A00-O?
      ENERGY STAR lists 8 certified combinations for this outdoor unit. The highest-rated ones use MVP-48-HP-MUAH-230A00-O, MCMP4860COTB, **AECMPT60D2AA.
      What refrigerant does the MRCOOL MVP-48-HP-C-230A00-O 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.
