      Questions6
      What is the SEER2 rating of the Samsung AR70H15CACWX?
      The Samsung AR70H15CACWX is rated at up to 23.0 SEER2 and 14.6 EER2 for cooling and up to 11.2 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the Samsung AR70H15CACWX good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 17,300 BTU/h at 5°F with a COP of 2.10, so it is still 2.1 times as efficient as electric resistance heat at that temperature.
      How much does the Samsung AR70H15CACWX cost to run per year?
      At its rated efficiency it costs about $307-$841 a year in electricity in large U.S. cities, depending on climate and local rates - for example $381 in Phoenix and $705 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the Samsung AR70H15CACWX the same as the Samsung AR70H15CAEBX?
      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.
      Which indoor units work with the Samsung AR70H15CACWX?
      ENERGY STAR lists 2 certified combinations for this outdoor unit. The highest-rated ones use SAMSUNG AR70H15CAEBN, SAMSUNG AR70H15CACWN.

      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.
