      Questions5
      What is the SEER2 rating of the TCL H09SUH25XGC?
      The TCL H09SUH25XGC is rated at up to 25.0 SEER2 and 14.5 EER2 for cooling and up to 10.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the TCL H09SUH25XGC good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 9,500 BTU/h at 5°F with a COP of 1.80, so it is still 1.8 times as efficient as electric resistance heat at that temperature.
      How much does the TCL H09SUH25XGC cost to run per year?
      At its rated efficiency it costs about $171-$549 a year in electricity in large U.S. cities, depending on climate and local rates - for example $223 in Phoenix and $468 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

      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.
