      Questions5
      What is the SEER2 rating of the YISO YOHA2-36CB?
      The YISO YOHA2-36CB is rated at up to 20.0 SEER2 and 13.0 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 54 certified matchups SEER2 ranges from 15.2-20.0.
      Is the YISO YOHA2-36CB good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 25,200 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 YISO YOHA2-36CB cost to run per year?
      At its rated efficiency it costs about $776-$2,144 a year in electricity in large U.S. cities, depending on climate and local rates - for example $966 in Phoenix and $1,798 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Which indoor units work with the YISO YOHA2-36CB?
      ENERGY STAR lists 54 certified combinations for this outdoor unit. The highest-rated ones use YAHA2-24CB, YAHA2-36CB, YAHA3-24DE.
      What refrigerant does the YISO YOHA2-36CB 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.
