      Questions6
      What is the SEER2 rating of the Innovair QOS09H1BM5A?
      The Innovair QOS09H1BM5A is rated at up to 23.0 SEER2 and 14.1 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 2 certified matchups SEER2 ranges from 22.0-23.0.
      Is the Innovair QOS09H1BM5A good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 9,200 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 Innovair QOS09H1BM5A cost to run per year?
      At its rated efficiency it costs about $187-$707 a year in electricity in large U.S. cities, depending on climate and local rates - for example $259 in Phoenix and $613 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the Innovair QOS09H1BM5A the same as the DENALI AIRE 2DNMSHQCO9A?
      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 Innovair QOS09H1BM5A?
      ENERGY STAR lists 2 certified combinations for this outdoor unit. The highest-rated ones use QHW09H1UZRA, QHW09H1BMRB.
      What refrigerant does the Innovair QOS09H1BM5A 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.
