      Questions6
      What is the SEER2 rating of the Innovair MOS06H2BH0A?
      The Innovair MOS06H2BH0A is rated at up to 25.5 SEER2 and 18.0 EER2 for cooling and up to 14.8 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the Innovair MOS06H2BH0A good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 7,700 BTU/h at 5°F with a COP of 2.39, so it is still 2.4 times as efficient as electric resistance heat at that temperature.
      How much does the Innovair MOS06H2BH0A cost to run per year?
      At its rated efficiency it costs about $111-$298 a year in electricity in large U.S. cities, depending on climate and local rates - for example $137 in Phoenix and $249 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the Innovair MOS06H2BH0A the same as the DIRECT AIR DIRM4-06HXPRO28-1Z?
      Yes, as far as the certified ratings go. ENERGY STAR lists 4 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 Innovair MOS06H2BH0A?
      ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses INNOVAIR MHW06H2BHRB.
      What refrigerant does the Innovair MOS06H2BH0A 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.
