      Questions6
      What is the SEER2 rating of the MOOVAIR MSHMA09C2AN1?
      The MOOVAIR MSHMA09C2AN1 is rated at up to 27.4 SEER2 and 15.4 EER2 for cooling and up to 13.8 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 3 certified matchups SEER2 ranges from 20.5-27.4.
      Is the MOOVAIR MSHMA09C2AN1 good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 11,900 BTU/h at 5°F with a COP of 1.85, so it is still 1.9 times as efficient as electric resistance heat at that temperature.
      How much does the MOOVAIR MSHMA09C2AN1 cost to run per year?
      At its rated efficiency it costs about $155-$449 a year in electricity in large U.S. cities, depending on climate and local rates - for example $196 in Phoenix and $379 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the MOOVAIR MSHMA09C2AN1 the same as the Stelpro SEPB-H09A-O?
      Yes, as far as the certified ratings go. ENERGY STAR lists both model numbers with identical efficiency, capacity and matchups, which means the same outdoor unit sold under a different brand or with a minor variant code (voltage, colour or region). The full list is on this page.
      Which indoor units work with the MOOVAIR MSHMA09C2AN1?
      ENERGY STAR lists 3 certified combinations for this outdoor unit. The highest-rated ones use MWHMA09C2AS1, GKHRA09C2AS1, GDHRA09C2AS1.
      What refrigerant does the MOOVAIR MSHMA09C2AN1 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.
