      Questions6
      What is the SEER2 rating of the Bosch BOVA-60RXB-M15S?
      The Bosch BOVA-60RXB-M15S is rated at up to 17.0 SEER2 and 11.7 EER2 for cooling and up to 8.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 19 certified matchups SEER2 ranges from 16.0-17.0.
      Is the Bosch BOVA-60RXB-M15S good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 39,500 BTU/h at 5°F with a COP of 1.87, so it is still 1.9 times as efficient as electric resistance heat at that temperature.
      How much does the Bosch BOVA-60RXB-M15S cost to run per year?
      At its rated efficiency it costs about $1,233-$3,454 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,541 in Phoenix and $2,902 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the Bosch BOVA-60RXB-M15S the same as the Midea MOVB-60HDN10-M16G?
      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 Bosch BOVA-60RXB-M15S?
      ENERGY STAR lists 19 certified combinations for this outdoor unit. The highest-rated ones use BIVA-48RCB-M20X, BIVA-36RCB-M20X, BIVB-48RCB-M20X.
      What refrigerant does the Bosch BOVA-60RXB-M15S 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.
