      A good fit if…

      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 12,000 BTU/h at 5°F.
      • You want steady temperatures and quiet running - the compressor varies its speed.

      Think twice if…

      • Cooling cost matters most - its SEER2 is below average for mini-splits.

      Questions5
      What is the SEER2 rating of the Friedrich FPHFR12A3D?
      The Friedrich FPHFR12A3D is rated at up to 21.0 SEER2 and 11.2 EER2 for cooling and up to 10.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 9 certified matchups SEER2 ranges from 19.5-21.0.
      Is the Friedrich FPHFR12A3D good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 12,000 BTU/h at 5°F with a COP of 1.80, so it is still 1.8 times as efficient as electric resistance heat at that temperature.
      How much does the Friedrich FPHFR12A3D cost to run per year?
      At its rated efficiency it costs about $269-$750 a year in electricity in large U.S. cities, depending on climate and local rates - for example $336 in Phoenix and $630 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 Friedrich FPHFR12A3D?
      ENERGY STAR lists 9 certified combinations for this outdoor unit. The highest-rated ones use Rheem FAHFW12A3D, Ruud FAHFW12A3D, FAHFW12A3D.
      What refrigerant does the Friedrich FPHFR12A3D use?

      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.
