      24,000 BTU mini-split heat pump · Clivia

      TOSOT TAVCI7H4R24

      Very good cooling efficiency and below average heating efficiency for a 24,000 BTU mini-split heat pump, but not rated for cold climates.

      Ranks #83 of 430 24,000 BTU mini-splits for cooling efficiency, and costs about $607 a year to run in a mixed climate like Atlanta.

      A good fit if…

      • You want low cooling bills - its SEER2 beats 70% 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.

      Questions6
      What is the SEER2 rating of the TOSOT TAVCI7H4R24?
      The TOSOT TAVCI7H4R24 is rated at up to 23.5 SEER2 and 12.0 EER2 for cooling and up to 9.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the TOSOT TAVCI7H4R24 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 24,000 BTU model.
      How much does the TOSOT TAVCI7H4R24 cost to run per year?
      At its rated efficiency it costs about $445-$1,530 a year in electricity in large U.S. cities, depending on climate and local rates - for example $596 in Phoenix and $1,315 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the TOSOT TAVCI7H4R24 the same as the TOSOT TW24WH25A1DO?
      Yes, as far as the certified ratings go. ENERGY STAR lists both model numbers with identical efficiency, capacity and matchups, which means the same outdoor unit sold under a different brand or with a minor variant code (voltage, colour or region). The full list is on this page.
      Which indoor units work with the TOSOT TAVCI7H4R24?
      ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses TAVEM7H4R24-S.
      What refrigerant does the TOSOT TAVCI7H4R24 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.
