      Questions5
      What is the SEER2 rating of the Hisense AMW4-36U3TQA?
      The Hisense AMW4-36U3TQA is rated at up to 22.0 SEER2 and 12.9 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 3 certified matchups SEER2 ranges from 19.0-22.0.
      Is the Hisense AMW4-36U3TQA good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 36,000 BTU/h at 5°F with a COP of 1.92, so it is still 1.9 times as efficient as electric resistance heat at that temperature.
      How much does the Hisense AMW4-36U3TQA cost to run per year?
      At its rated efficiency it costs about $772-$2,232 a year in electricity in large U.S. cities, depending on climate and local rates - for example $975 in Phoenix and $1,883 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the Hisense AMW4-36U3TQA the same as the Hisense AMO4-36U3T25U?
      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.
      What refrigerant does the Hisense AMW4-36U3TQA 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.
