      A good fit if…

      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 40,000 BTU/h at 5°F.
      • It will heat most of the year - its HSPF2 beats 79% of central heat pumps.
      • 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 VillaTherm VHP-UCHA-60HDCT-A?
      The VillaTherm VHP-UCHA-60HDCT-A is rated at up to 17.0 SEER2 and 9.5 EER2 for cooling and up to 9.8 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 5 certified matchups SEER2 ranges from 16.2-17.0.
      Is the VillaTherm VHP-UCHA-60HDCT-A good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 40,000 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 VillaTherm VHP-UCHA-60HDCT-A cost to run per year?
      At its rated efficiency it costs about $1,455-$3,579 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,778 in Phoenix and $2,948 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 VillaTherm VHP-UCHA-60HDCT-A?

      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.
