      Questions6
      What is the SEER2 rating of the Friedrich FPHSR12A3B?
      The Friedrich FPHSR12A3B is rated at up to 23.0 SEER2 and 12.3 EER2 for cooling and up to 10.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the Friedrich FPHSR12A3B good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 11,000 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 Friedrich FPHSR12A3B cost to run per year?
      At its rated efficiency it costs about $246-$738 a year in electricity in large U.S. cities, depending on climate and local rates - for example $315 in Phoenix and $625 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the Friedrich FPHSR12A3B the same as the Innovair QOS12H2BM5A?
      Yes, as far as the certified ratings go. ENERGY STAR lists both 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 Friedrich FPHSR12A3B?
      ENERGY STAR lists 2 certified combinations for this outdoor unit. The highest-rated ones use FRIEDRICH FAHFW12A3A, FRIEDRICH FAHFW12A3D.
      What refrigerant does the Friedrich FPHSR12A3B 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.
