      A good fit if…

      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 18,500 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.

      Questions4
      What is the SEER2 rating of the ROVSUN TC-24CHRH/DVO?
      The ROVSUN TC-24CHRH/DVO is rated at up to 19.0 SEER2 and 11.0 EER2 for cooling and up to 10.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the ROVSUN TC-24CHRH/DVO good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 18,500 BTU/h at 5°F with a COP of 2.00, so it is still 2.0 times as efficient as electric resistance heat at that temperature.
      How much does the ROVSUN TC-24CHRH/DVO cost to run per year?
      At its rated efficiency it costs about $546-$1,555 a year in electricity in large U.S. cities, depending on climate and local rates - for example $686 in Phoenix and $1,310 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      What refrigerant does the ROVSUN TC-24CHRH/DVO use?
      It uses R-454B.

      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.
