A good fit if…

  • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 30,600 BTU/h at 5°F.

Think twice if…

  • 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.
  • You want the newest refrigerant - it uses R-410A, which is being phased down.

Questions5
What is the SEER2 rating of the Rheem WP15AZ60AJ2N?
The Rheem WP15AZ60AJ2N is rated at up to 16.0 SEER2 and 11.7 EER2 for cooling and up to 8.1 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 8 certified matchups SEER2 ranges from 15.2-16.0.
Is the Rheem WP15AZ60AJ2N good for cold climates?
Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 30,600 BTU/h at 5°F with a COP of 2.30, so it is still 2.3 times as efficient as electric resistance heat at that temperature.
How much does the Rheem WP15AZ60AJ2N cost to run per year?
At its rated efficiency it costs about $1,674-$4,451 a year in electricity in large U.S. cities, depending on climate and local rates - for example $2,060 in Phoenix and $3,716 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 WP15AZ60AJ2N?
ENERGY STAR lists 8 certified combinations for this outdoor unit. The highest-rated ones use FHRNTT6024S*ZTNA, RH2TZ6024STANN, WH2TZ6024STANN.
What refrigerant does the Rheem WP15AZ60AJ2N use?
It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and 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.
