      A good fit if…

      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 38,500 BTU/h at 5°F.
      • You want steady temperatures and quiet running - the compressor varies its speed.

      Think twice if…

      • Nothing stands out - its ratings have no weak spot for its class.

      Questions5
      What is the SEER2 rating of the UTL UCHA-60HDCT?
      The UTL UCHA-60HDCT is rated at up to 17.0 SEER2 and 9.5 EER2 for cooling and up to 9.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the UTL UCHA-60HDCT good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 38,500 BTU/h at 5°F with a COP of 2.20, so it is still 2.2 times as efficient as electric resistance heat at that temperature.
      How much does the UTL UCHA-60HDCT cost to run per year?
      At its rated efficiency it costs about $1,490-$3,829 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,815 in Phoenix and $3,182 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 UTL UCHA-60HDCT?
      ENERGY STAR lists 3 certified combinations for this outdoor unit. The highest-rated one uses UCHA-60HDC.
      What refrigerant does the UTL UCHA-60HDCT 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.
