      A good fit if…

      • You want low cooling bills - its SEER2 beats 91% of mini-splits.
      • It will heat most of the year - its HSPF2 beats 71% of mini-splits.
      • 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.

      Questions5
      What is the SEER2 rating of the Fujitsu AOUH09KPAS1?
      The Fujitsu AOUH09KPAS1 is rated at up to 26.0 SEER2 and 12.5 EER2 for cooling and up to 10.8 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the Fujitsu AOUH09KPAS1 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 9,000 BTU model.
      How much does the Fujitsu AOUH09KPAS1 cost to run per year?
      At its rated efficiency it costs about $164-$556 a year in electricity in large U.S. cities, depending on climate and local rates - for example $219 in Phoenix and $477 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 Fujitsu AOUH09KPAS1?
      ENERGY STAR lists 2 certified combinations for this outdoor unit. The highest-rated ones use FUJITSU ASUH09KPAS, FUJITSU ASUH09KPBS.
      What refrigerant does the Fujitsu AOUH09KPAS1 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.
