      A good fit if…

      • You want steady temperatures and quiet running - the compressor varies its speed.

      Think twice if…

      • You often see nights below 0°F - it is not cold-climate certified.
      • Cooling cost matters most - its SEER2 is below average for central heat pumps.
      • You mainly need heat - its HSPF2 is below average for central heat pumps.

      Questions5
      What is the SEER2 rating of the MRCOOL MVP-18-HP-C-230A00-O?
      The MRCOOL MVP-18-HP-C-230A00-O is rated at up to 16.4 SEER2 and 11.0 EER2 for cooling and up to 8.4 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 4 certified matchups SEER2 ranges from 16.1-16.4.
      Is the MRCOOL MVP-18-HP-C-230A00-O 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 1.5-ton model.
      How much does the MRCOOL MVP-18-HP-C-230A00-O cost to run per year?
      At its rated efficiency it costs about $516-$1,419 a year in electricity in large U.S. cities, depending on climate and local rates - for example $642 in Phoenix and $1,190 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-18-HP-C-230A00-O?
      ENERGY STAR lists 4 certified combinations for this outdoor unit. The highest-rated ones use MCMP1824BOTB, **AECMPT24B2AA.
      What refrigerant does the MRCOOL MVP-18-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.
