      Questions6
      What is the SEER2 rating of the Trane 5TWV0X60A1?
      The Trane 5TWV0X60A1 is rated at up to 19.0 SEER2 and 10.5 EER2 for cooling and up to 9.4 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 66 certified matchups SEER2 ranges from 18.2-19.0.
      Is the Trane 5TWV0X60A1 good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 38,500 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 Trane 5TWV0X60A1 cost to run per year?
      At its rated efficiency it costs about $1,312-$3,605 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,631 in Phoenix and $3,022 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the Trane 5TWV0X60A1 the same as the American Standard 5A6V0X60A1?
      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 Trane 5TWV0X60A1?
      ENERGY STAR lists 66 certified combinations for this outdoor unit. The highest-rated ones use 5PX*D010AS3+P0V0D000M50SD+LRP, 5PX*D010AS3+P0V0C000M50SD+LRP, 5TXCD010AS3+P0V0C000M50SD+LRP.
      What refrigerant does the Trane 5TWV0X60A1 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.
