      Questions5
      What is the SEER2 rating of the VillaTherm VHP-UCHA-24HDCT-A?
      The VillaTherm VHP-UCHA-24HDCT-A is rated at up to 20.0 SEER2 and 14.0 EER2 for cooling and up to 10.2 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 5 certified matchups SEER2 ranges from 19.0-20.0.
      Is the VillaTherm VHP-UCHA-24HDCT-A good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 24,000 BTU/h at 5°F with a COP of 2.30, so it is still 2.3 times as efficient as electric resistance heat at that temperature.
      How much does the VillaTherm VHP-UCHA-24HDCT-A cost to run per year?
      At its rated efficiency it costs about $564-$1,490 a year in electricity in large U.S. cities, depending on climate and local rates - for example $693 in Phoenix and $1,243 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

      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.
