      Questions5
      What is the SEER2 rating of the Innovair SHV24H2BA?
      The Innovair SHV24H2BA is rated at up to 18.6 SEER2 and 12.0 EER2 for cooling and up to 10.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 10 certified matchups SEER2 ranges from 15.3-18.6.
      Is the Innovair SHV24H2BA good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 21,600 BTU/h at 5°F with a COP of 2.14, so it is still 2.1 times as efficient as electric resistance heat at that temperature.
      How much does the Innovair SHV24H2BA cost to run per year?

      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.
