      Questions5
      What is the SEER2 rating of the TCL H24SBH20XPC?
      The TCL H24SBH20XPC is rated at up to 23.0 SEER2 and 12.0 EER2 for cooling and up to 10.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 5 certified matchups SEER2 ranges from 19.0-23.0.
      Is the TCL H24SBH20XPC good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 19,300 BTU/h at 5°F with a COP of 2.00, so it is still 2.0 times as efficient as electric resistance heat at that temperature.
      How much does the TCL H24SBH20XPC cost to run per year?
      At its rated efficiency it costs about $456-$1,366 a year in electricity in large U.S. cities, depending on climate and local rates - for example $582 in Phoenix and $1,157 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 TCL H24SBH20XPC?
      ENERGY STAR lists 5 certified combinations for this outdoor unit. The highest-rated ones use H24SBH20XPE, H24CSHU1XAE, H24FCHU1XAE.
      What refrigerant does the TCL H24SBH20XPC 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.
