      A good fit if…

      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 19,300 BTU/h at 5°F.
      • You want a choice of indoor units - 57 certified pairings.

      Think twice if…

      • Cooling cost matters most - its SEER2 is below average for central heat pumps.
      • You mainly need heat - its HSPF2 is below average for central heat pumps.

      Questions5
      What is the SEER2 rating of the Fujitsu FOP1542TJAYNA?
      The Fujitsu FOP1542TJAYNA is rated at up to 16.0 SEER2 and 11.7 EER2 for cooling and up to 8.1 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 57 certified matchups SEER2 ranges from 15.2-16.0.
      Is the Fujitsu FOP1542TJAYNA good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 19,300 BTU/h at 5°F with a COP of 2.00, so it is still 2.0 times as efficient as electric resistance heat at that temperature.
      How much does the Fujitsu FOP1542TJAYNA cost to run per year?
      At its rated efficiency it costs about $1,175-$3,124 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,446 in Phoenix and $2,608 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 FOP1542TJAYNA?
      ENERGY STAR lists 57 certified combinations for this outdoor unit. The highest-rated ones use FCCN4821SYTA, FCCN4824SYTA, FHRNTT4821S*YTNA.
      What refrigerant does the Fujitsu FOP1542TJAYNA 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.
