      A good fit if…

      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 9,100 BTU/h at 5°F.
      • You want steady temperatures and quiet running - the compressor varies its speed.

      Think twice if…

      • You mainly need heat - its HSPF2 is below average for mini-splits.
      • You want the newest refrigerant - it uses R-410A, which is being phased down.

      Questions6
      What is the SEER2 rating of the TCL TSC-12HA2/I3TI23?
      The TCL TSC-12HA2/I3TI23 is rated at up to 23.0 SEER2 and 13.0 EER2 for cooling and up to 9.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the TCL TSC-12HA2/I3TI23 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 TSC-12HA2/I3TI23 cost to run per year?
      At its rated efficiency it costs about $247-$771 a year in electricity in large U.S. cities, depending on climate and local rates - for example $320 in Phoenix and $656 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the TCL TSC-12HA2/I3TI23 the same as the Pioneer YN012GLFI22RPD?
      Yes, as far as the certified ratings go. ENERGY STAR lists 10 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 TSC-12HA2/I3TI23?
      ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses TSC-12HA2/I3TI23-I.
      What refrigerant does the TCL TSC-12HA2/I3TI23 use?
      It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and R-32.

      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.
