      4-ton central heat pump · TOSOT UNIX Series

      TOSOT TU60-32GDU

      Very good cooling and heating efficiency for a 4-ton central heat pump, but not rated for cold climates.

      Ranks #58 of 319 4 ton central heat pumps for cooling efficiency, and costs about $1,494 a year to run in a mixed climate like Atlanta.

      A good fit if…

      • You want low cooling bills - its SEER2 beats 85% of central heat pumps.
      • It will heat most of the year - its HSPF2 beats 70% of central heat pumps.
      • 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.

      Questions6
      What is the SEER2 rating of the TOSOT TU60-32GDU?
      The TOSOT TU60-32GDU is rated at up to 19.0 SEER2 and 11.5 EER2 for cooling and up to 9.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the TOSOT TU60-32GDU 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 4-ton model.
      How much does the TOSOT TU60-32GDU cost to run per year?
      At its rated efficiency it costs about $1,324-$3,580 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,638 in Phoenix and $2,996 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the TOSOT TU60-32GDU the same as the Blueridge BNG2Z60SCM?
      Yes, as far as the certified ratings go. ENERGY STAR lists 3 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 TU60-32GDU?
      ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses TU60-32AH2GDU.
      What refrigerant does the TOSOT TU60-32GDU 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.
