      A good fit if…

      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 35,000 BTU/h at 5°F.
      • You want steady temperatures and quiet running - the compressor varies its speed.

      Think twice if…

      • Nothing stands out - its ratings have no weak spot for its class.

      Questions6
      What is the SEER2 rating of the Friedrich WFPU17Y483D?
      The Friedrich WFPU17Y483D is rated at up to 18.0 SEER2 and 10.0 EER2 for cooling and up to 9.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the Friedrich WFPU17Y483D good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 35,000 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 WFPU17Y483D cost to run per year?
      At its rated efficiency it costs about $1,253-$3,365 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,547 in Phoenix and $2,813 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the Friedrich WFPU17Y483D the same as the Hisense AOH-48T3T25U?
      Yes, as far as the certified ratings go. ENERGY STAR lists 4 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 WFPU17Y483D?
      ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses WFH48Y223D.
      What refrigerant does the Friedrich WFPU17Y483D 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.
