      Questions5
      What is the SEER2 rating of the MRCOOL CENTRAL-36-HP-C-230B00-O?
      The MRCOOL CENTRAL-36-HP-C-230B00-O is rated at up to 17.4 SEER2 and 11.7 EER2 for cooling and up to 10.3 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 21 certified matchups SEER2 ranges from 15.2-17.4.
      Is the MRCOOL CENTRAL-36-HP-C-230B00-O good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 39,000 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 MRCOOL CENTRAL-36-HP-C-230B00-O cost to run per year?
      At its rated efficiency it costs about $969-$2,382 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,166 in Phoenix and $1,968 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 CENTRAL-36-HP-C-230B00-O?
      ENERGY STAR lists 21 certified combinations for this outdoor unit. The highest-rated ones use MVP-36-HP-MUAH-230A00-O, MCMP3036BOTB, **AECMPT36B2AA.
      What refrigerant does the MRCOOL CENTRAL-36-HP-C-230B00-O 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.
