      9,000 BTU mini-split heat pump · K series

      KANIONco KWSM-09IR410AHS24MVL

      Very good cooling efficiency and below average heating efficiency for a 9,000 BTU mini-split heat pump, but not rated for cold climates.

      Ranks #209 of 395 9,000 BTU mini-splits for cooling efficiency, and costs about $246 a year to run in a mixed climate like Atlanta.

      A good fit if…

      • You want low cooling bills - its SEER2 beats 75% 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 mainly need heat - its HSPF2 is below average for mini-splits.
      • You want the newest refrigerant - it uses R-410A, which is being phased down.

      Questions5
      What is the SEER2 rating of the KANIONco KWSM-09IR410AHS24MVL?
      The KANIONco KWSM-09IR410AHS24MVL is rated at up to 24.0 SEER2 and 14.0 EER2 for cooling and up to 9.6 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the KANIONco KWSM-09IR410AHS24MVL 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 KANIONco KWSM-09IR410AHS24MVL cost to run per year?
      At its rated efficiency it costs about $178-$622 a year in electricity in large U.S. cities, depending on climate and local rates - for example $240 in Phoenix and $535 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 KANIONco KWSM-09IR410AHS24MVL?
      ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses KWSM-09IR410AHS24MVL.
      What refrigerant does the KANIONco KWSM-09IR410AHS24MVL 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.
