      A good fit if…

      • You want low cooling bills - its SEER2 beats 91% of mini-splits.
      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 13,400 BTU/h at 5°F.
      • It will heat most of the year - its HSPF2 beats 86% of mini-splits.
      • You want steady temperatures and quiet running - the compressor varies its speed.

      Think twice if…

      • You want the newest refrigerant - it uses R-410A, which is being phased down.

      Questions5
      What is the SEER2 rating of the Fujitsu AOU9RLFFH?
      The Fujitsu AOU9RLFFH is rated at up to 26.0 SEER2 and 16.0 EER2 for cooling and up to 11.6 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the Fujitsu AOU9RLFFH good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 13,400 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 Fujitsu AOU9RLFFH cost to run per year?
      At its rated efficiency it costs about $163-$480 a year in electricity in large U.S. cities, depending on climate and local rates - for example $207 in Phoenix and $405 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 AOU9RLFFH?
      ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses FUJITSU AGU9RLF.
      What refrigerant does the Fujitsu AOU9RLFFH use?
      It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and 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.
