      Questions5
      What is the SEER2 rating of the MOOVAIR MSHEA09C2AN?
      The MOOVAIR MSHEA09C2AN is rated at up to 25.8 SEER2 and 14.9 EER2 for cooling and up to 12.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the MOOVAIR MSHEA09C2AN good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 8,000 BTU/h at 5°F with a COP of 2.36, so it is still 2.4 times as efficient as electric resistance heat at that temperature.
      How much does the MOOVAIR MSHEA09C2AN cost to run per year?
      At its rated efficiency it costs about $165-$492 a year in electricity in large U.S. cities, depending on climate and local rates - for example $210 in Phoenix and $417 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 MOOVAIR MSHEA09C2AN?
      ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses MWHEA09C2AN.

      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.
