      A good fit if…

      • You want low cooling bills - its SEER2 beats 79% of packaged heat pumps.
      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 9,000 BTU/h at 5°F.
      • It will heat most of the year - its HSPF2 beats 83% of packaged 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.

      Questions4
      What is the SEER2 rating of the Multi MFG 12SPV0-HP-X-D?
      The Multi MFG 12SPV0-HP-X-D is rated at up to 17.1 SEER2 and 10.5 EER2 for cooling and up to 8.6 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the Multi MFG 12SPV0-HP-X-D good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 9,000 BTU/h at 5°F with a COP of 2.00, so it is still 2.0 times as efficient as electric resistance heat at that temperature.
      How much does the Multi MFG 12SPV0-HP-X-D cost to run per year?
      At its rated efficiency it costs about $330-$881 a year in electricity in large U.S. cities, depending on climate and local rates - for example $406 in Phoenix and $736 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      What refrigerant does the Multi MFG 12SPV0-HP-X-D 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.
