      A good fit if…

      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 8,400 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 mini-splits.
      • You mainly need heat - its HSPF2 is below average for mini-splits.

      Questions6
      What is the SEER2 rating of the MDV MOX130-12HFN8-B1L?
      The MDV MOX130-12HFN8-B1L is rated at up to 19.5 SEER2 and 9.0 EER2 for cooling and up to 9.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the MDV MOX130-12HFN8-B1L good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 8,400 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 MDV MOX130-12HFN8-B1L cost to run per year?
      At its rated efficiency it costs about $289-$793 a year in electricity in large U.S. cities, depending on climate and local rates - for example $360 in Phoenix and $665 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the MDV MOX130-12HFN8-B1L the same as the Innovair MOS12H1XE5A?
      Yes, as far as the certified ratings go. ENERGY STAR lists both model numbers with identical efficiency, capacity and matchups, which means the same outdoor unit sold under a different brand or with a minor variant code (voltage, colour or region). The full list is on this page.
      Which indoor units work with the MDV MOX130-12HFN8-B1L?
      ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses MSGPB-12HRFN8-B1L.
      What refrigerant does the MDV MOX130-12HFN8-B1L use?
      It uses 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.
