      A good fit if…

      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 18,000 BTU/h at 5°F.
      • It will heat most of the year - its HSPF2 beats 84% of central heat pumps.
      • You want steady temperatures and quiet running - the compressor varies its speed.

      Think twice if…

      • Nothing stands out - its ratings have no weak spot for its class.

      Questions5
      What is the SEER2 rating of the Midea MDV-V18WMN10T?
      The Midea MDV-V18WMN10T is rated at up to 17.5 SEER2 and 12.0 EER2 for cooling and up to 10.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 8 certified matchups SEER2 ranges from 15.2-17.5.
      Is the Midea MDV-V18WMN10T good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 18,000 BTU/h at 5°F with a COP of 1.95, so it is still 2.0 times as efficient as electric resistance heat at that temperature.
      How much does the Midea MDV-V18WMN10T cost to run per year?
      At its rated efficiency it costs about $475-$1,167 a year in electricity in large U.S. cities, depending on climate and local rates - for example $577 in Phoenix and $962 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 Midea MDV-V18WMN10T?
      ENERGY STAR lists 8 certified combinations for this outdoor unit. The highest-rated ones use MVME24B2MN10TB, MIH18VMN10, MPCE18A1MN10TA.
      What refrigerant does the Midea MDV-V18WMN10T 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.
