      Questions5
      What is the SEER2 rating of the Friedrich FRP15AY18AJ2N?
      The Friedrich FRP15AY18AJ2N 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 10 certified matchups SEER2 ranges from 15.2-16.0.
      Is the Friedrich FRP15AY18AJ2N good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 8,700 BTU/h at 5°F with a COP of 2.00, so it is still 2.0 times as efficient as electric resistance heat at that temperature.
      How much does the Friedrich FRP15AY18AJ2N cost to run per year?
      At its rated efficiency it costs about $502-$1,335 a year in electricity in large U.S. cities, depending on climate and local rates - for example $618 in Phoenix and $1,115 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

      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.
