      A good fit if…

      • You want low cooling bills - its SEER2 beats 83% 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.

      Questions5
      What is the SEER2 rating of the Deye DWA4-09KR2(US)?
      The Deye DWA4-09KR2(US) is rated at up to 25.0 SEER2 and 14.5 EER2 for cooling and up to 10.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the Deye DWA4-09KR2(US) 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 9,000 BTU model.
      How much does the Deye DWA4-09KR2(US) cost to run per year?
      At its rated efficiency it costs about $171-$549 a year in electricity in large U.S. cities, depending on climate and local rates - for example $223 in Phoenix and $468 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 Deye DWA4-09KR2(US)?
      ENERGY STAR lists 3 certified combinations for this outdoor unit. The highest-rated ones use DGA3-09KR2(US), airspool DGA3-09KR2(US), EG4 DGA3-09KR2(US).

      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.
