A good fit if…

  • You want a certified 4-ton central heat pump at a typical efficiency level.

Think twice if…

  • You often see nights below 0°F - it is not cold-climate certified.
  • 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.

Questions6
What is the SEER2 rating of the Fujitsu FOP1548TJAYNA?
The Fujitsu FOP1548TJAYNA is rated at up to 15.2 SEER2 and 11.7 EER2 for cooling and up to 7.8 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
Is the Fujitsu FOP1548TJAYNA 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 4-ton model.
How much does the Fujitsu FOP1548TJAYNA cost to run per year?
At its rated efficiency it costs about $1,406-$3,699 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,725 in Phoenix and $3,084 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
Is the Fujitsu FOP1548TJAYNA the same as the Friedrich FWP15AY48AJ2N?
Yes, as far as the certified ratings go. ENERGY STAR lists 3 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 Fujitsu FOP1548TJAYNA?
ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses FHRNTT4821S*YTNA.
What refrigerant does the Fujitsu FOP1548TJAYNA 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.
