      A good fit if…

      • You want a choice of indoor units - 167 certified pairings.

      Think twice if…

      • You often see nights below 0°F - it is not cold-climate certified.
      • Cooling cost matters most - its SEER2 is below average for central heat pumps.
      • You mainly need heat - its HSPF2 is below average for central heat pumps.

      Questions5
      What is the SEER2 rating of the Rheem RP15AY36AJ2N?
      The Rheem RP15AY36AJ2N is rated at up to 16.0 SEER2 and 11.7 EER2 for cooling and up to 7.8 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 167 certified matchups SEER2 ranges from 15.2-16.0.
      Is the Rheem RP15AY36AJ2N 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 Rheem RP15AY36AJ2N cost to run per year?
      At its rated efficiency it costs about $1,005-$2,754 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,248 in Phoenix and $2,307 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 Rheem RP15AY36AJ2N?
      ENERGY STAR lists 167 certified combinations for this outdoor unit. The highest-rated ones use RCFY3621STANM, RCFY3617STANM, RH2VY3621STACN.
      What refrigerant does the Rheem RP15AY36AJ2N 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.
