      A good fit if…

      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 34,000 BTU/h at 5°F.
      • It will heat most of the year - its HSPF2 beats 75% of mini-splits.
      • 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 Fujitsu AOUH30KUAH1?
      The Fujitsu AOUH30KUAH1 is rated at up to 23.0 SEER2 and 13.7 EER2 for cooling and up to 11.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 4 certified matchups SEER2 ranges from 18.0-23.0.
      Is the Fujitsu AOUH30KUAH1 good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 34,000 BTU/h at 5°F with a COP of 2.16, so it is still 2.2 times as efficient as electric resistance heat at that temperature.
      How much does the Fujitsu AOUH30KUAH1 cost to run per year?
      At its rated efficiency it costs about $615-$1,799 a year in electricity in large U.S. cities, depending on climate and local rates - for example $780 in Phoenix and $1,520 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 AOUH30KUAH1?
      ENERGY STAR lists 4 certified combinations for this outdoor unit. The highest-rated ones use FUJITSU AUUH30KUAS, FUJITSU ABUH30KUAS, FUJITSU AMUH30KUAS.
      What refrigerant does the Fujitsu AOUH30KUAH1 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.
