      A good fit if…

      • You want low cooling bills - its SEER2 beats 91% 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.

      Questions5
      What is the SEER2 rating of the Trane/American Standard 5HPL9036A1000A?
      The Trane/American Standard 5HPL9036A1000A is rated at up to 19.5 SEER2 and 12.1 EER2 for cooling and up to 9.2 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the Trane/American Standard 5HPL9036A1000A 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 3-ton model.
      How much does the Trane/American Standard 5HPL9036A1000A cost to run per year?
      At its rated efficiency it costs about $873-$2,665 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,122 in Phoenix and $2,261 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Which indoor units work with the Trane/American Standard 5HPL9036A1000A?
      ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses 5TEM9D04AC31SA.
      What refrigerant does the Trane/American Standard 5HPL9036A1000A use?

      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.
