      A good fit if…

      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 24,000 BTU/h at 5°F.
      • You want steady temperatures and quiet running - the compressor varies its speed.

      Think twice if…

      • Cooling cost matters most - its SEER2 is below average for mini-splits.
      • You mainly need heat - its HSPF2 is below average for mini-splits.

      Questions5
      What is the SEER2 rating of the Daikin RXP24AVJU?
      The Daikin RXP24AVJU is rated at up to 18.3 SEER2 and 10.3 EER2 for cooling and up to 9.2 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the Daikin RXP24AVJU good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 24,000 BTU/h at 5°F with a COP of 1.80, so it is still 1.8 times as efficient as electric resistance heat at that temperature.
      How much does the Daikin RXP24AVJU cost to run per year?
      At its rated efficiency it costs about $562-$1,619 a year in electricity in large U.S. cities, depending on climate and local rates - for example $709 in Phoenix and $1,365 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 Daikin RXP24AVJU?
      ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses DAIKIN FDMA24AVJU.
      What refrigerant does the Daikin RXP24AVJU 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.
