      Questions6
      What is the SEER2 rating of the Trane 5TWR7024A1?
      The Trane 5TWR7024A1 is rated at up to 17.1 SEER2 and 12.5 EER2 for cooling and up to 11.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 245 certified matchups SEER2 ranges from 15.2-17.1.
      Is the Trane 5TWR7024A1 good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 17,700 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 5TWR7024A1 cost to run per year?
      At its rated efficiency it costs about $530-$1,339 a year in electricity in large U.S. cities, depending on climate and local rates - for example $730 in Phoenix and $1,081 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the Trane 5TWR7024A1 the same as the American Standard 5A6H7024A1?
      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 5TWR7024A1?
      ENERGY STAR lists 245 certified combinations for this outdoor unit. The highest-rated ones use 5TXCB004AS3+P0V0B000M40SD, 5TEMCD05AV41+TDR, 5TEMCD04AV31+TDR.
      What refrigerant does the Trane 5TWR7024A1 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.
