      A good fit if…

      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 36,000 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.

      Questions5
      What is the SEER2 rating of the TOSOT TM36D6MO?
      The TOSOT TM36D6MO is rated at up to 21.0 SEER2 and 12.0 EER2 for cooling and up to 10.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 3 certified matchups SEER2 ranges from 18.0-21.0.
      Is the TOSOT TM36D6MO good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 36,000 BTU/h at 5°F with a COP of 2.10, so it is still 2.1 times as efficient as electric resistance heat at that temperature.
      How much does the TOSOT TM36D6MO cost to run per year?
      At its rated efficiency it costs about $807-$2,251 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,008 in Phoenix and $1,891 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the TOSOT TM36D6MO the same as the TOSOT TM36H32MO?
      Yes, as far as the certified ratings go. ENERGY STAR lists 20 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.
      What refrigerant does the TOSOT TM36D6MO 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.
