      12,000 BTU mini-split heat pump · Arctic

      Haier 1U12EH2VHE

      Excellent cooling efficiency and very good heating efficiency for a 12,000 BTU mini-split heat pump, but not rated for cold climates.

      Ranks #24 of 394 12,000 BTU mini-splits for cooling efficiency, and costs about $287 a year to run in a mixed climate like Atlanta.

      A good fit if…

      • You want low cooling bills - its SEER2 beats 94% of mini-splits.
      • It will heat most of the year - its HSPF2 beats 89% of mini-splits.
      • 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 want the newest refrigerant - it uses R-410A, which is being phased down.

      Questions5
      What is the SEER2 rating of the Haier 1U12EH2VHE?
      The Haier 1U12EH2VHE is rated at up to 27.0 SEER2 and 15.0 EER2 for cooling and up to 12.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the Haier 1U12EH2VHE 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 12,000 BTU model.
      How much does the Haier 1U12EH2VHE cost to run per year?
      At its rated efficiency it costs about $211-$724 a year in electricity in large U.S. cities, depending on climate and local rates - for example $283 in Phoenix and $622 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 Haier 1U12EH2VHE?
      ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses HAIER AW12EH2VHD.
      What refrigerant does the Haier 1U12EH2VHE use?
      It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and 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.
