      Questions6
      What is the SEER2 rating of the TCL TSH09HEI2NAP0T24U?
      The TCL TSH09HEI2NAP0T24U 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 TSH09HEI2NAP0T24U good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 9,100 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 TSH09HEI2NAP0T24U cost to run per year?
      At its rated efficiency it costs about $170-$524 a year in electricity in large U.S. cities, depending on climate and local rates - for example $219 in Phoenix and $445 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the TCL TSH09HEI2NAP0T24U the same as the ZERO ZMSB-09HVT-USHHCR2?
      Yes, as far as the certified ratings go. ENERGY STAR lists 7 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 TCL TSH09HEI2NAP0T24U?
      ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses TSH09IEI2NAO0T24U.
      What refrigerant does the TCL TSH09HEI2NAP0T24U 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.
