      A good fit if…

      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 9,200 BTU/h at 5°F.
      • You want steady temperatures and quiet running - the compressor varies its speed.

      Think twice if…

      • You mainly need heat - its HSPF2 is below average for mini-splits.

      Questions5
      What is the SEER2 rating of the Friedrich FPHSR12A1C?
      The Friedrich FPHSR12A1C is rated at up to 22.0 SEER2 and 12.3 EER2 for cooling and up to 9.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the Friedrich FPHSR12A1C good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 9,200 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 Friedrich FPHSR12A1C cost to run per year?
      At its rated efficiency it costs about $258-$776 a year in electricity in large U.S. cities, depending on climate and local rates - for example $330 in Phoenix and $658 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 FPHSR12A1C?
      ENERGY STAR lists 4 certified combinations for this outdoor unit. The highest-rated ones use Rheem FAHSW12A1C, Ruud FAHSW12A1C, FAHSW12A1C.
      What refrigerant does the Friedrich FPHSR12A1C 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.
