      A good fit if…

      • You want steady temperatures and quiet running - the compressor varies its speed.

      Think twice if…

      • You often see nights below 0°F - it is not cold-climate certified.
      • You mainly need heat - its HSPF2 is below average for mini-splits.

      Questions5
      What is the SEER2 rating of the York YRAMG36N4HAA?
      The York YRAMG36N4HAA is rated at up to 23.0 SEER2 and 12.0 EER2 for cooling and up to 9.3 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 3 certified matchups SEER2 ranges from 18.0-23.0.
      Is the York YRAMG36N4HAA good for cold climates?
      It is not cold-climate certified: none of its matchups meet the ENERGY STAR cold-climate criteria (a COP of at least 1.75 at 5°F among other limits). In places with frequent sub-zero nights, pick a cold-climate 36,000 BTU model.
      How much does the York YRAMG36N4HAA cost to run per year?
      At its rated efficiency it costs about $741-$2,353 a year in electricity in large U.S. cities, depending on climate and local rates - for example $965 in Phoenix and $2,006 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the York YRAMG36N4HAA the same as the York YRAMG36N4HBA?
      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.
      What refrigerant does the York YRAMG36N4HAA use?
      It uses R-32.

      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.
