      A good fit if…

      • 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.
      • Cooling cost matters most - its SEER2 is below average for mini-splits.

      Questions5
      What is the SEER2 rating of the TOSOT TGWHD-60ND?
      The TOSOT TGWHD-60ND is rated at up to 21.0 SEER2 and 11.7 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 19.0-21.0.
      Is the TOSOT TGWHD-60ND 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 60,000 BTU model.
      How much does the TOSOT TGWHD-60ND cost to run per year?
      At its rated efficiency it costs about $1,233-$3,439 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,540 in Phoenix and $2,888 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the TOSOT TGWHD-60ND the same as the TOSOT TM60WH21MO?
      Yes, as far as the certified ratings go. ENERGY STAR lists 9 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 TGWHD-60ND 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.
