      3-ton central heat pump · NG2

      Blueridge BNG2Z36SCM

      Very good cooling efficiency and below average heating efficiency for a 3-ton central heat pump, but not rated for cold climates.

      Ranks #64 of 302 3 ton central heat pumps for cooling efficiency, and costs about $1,030 a year to run in a mixed climate like Atlanta.

      A good fit if…

      • You want low cooling bills - its SEER2 beats 85% of central heat pumps.
      • You want steady temperatures and quiet running - the compressor varies its speed.

      Think twice if…

      • You often see nights below 0°F - it is not cold-climate certified.
      • You mainly need heat - its HSPF2 is below average for central heat pumps.

      Questions6
      What is the SEER2 rating of the Blueridge BNG2Z36SCM?
      The Blueridge BNG2Z36SCM is rated at up to 19.0 SEER2 and 11.5 EER2 for cooling and up to 8.3 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the Blueridge BNG2Z36SCM good for cold climates?
      It is not cold-climate certified: none of its matchups meet the ENERGY STAR cold-climate criteria (a COP of at least 1.75 at 5°F among other limits). In places with frequent sub-zero nights, pick a cold-climate 3-ton model.
      How much does the Blueridge BNG2Z36SCM cost to run per year?
      At its rated efficiency it costs about $845-$2,522 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,078 in Phoenix and $2,136 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the Blueridge BNG2Z36SCM the same as the Blueridge BNG2Z36SCN?
      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 Blueridge BNG2Z36SCM?
      ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses BNGFZ36DH0.
      What refrigerant does the Blueridge BNG2Z36SCM use?
      It uses R-32.

      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.
