      A good fit if…

      • You want low cooling bills - its SEER2 beats 85% of central heat pumps.
      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 18,400 BTU/h at 5°F.
      • It will heat most of the year - its HSPF2 beats 84% of central heat pumps.
      • You want steady temperatures and quiet running - the compressor varies its speed.

      Think twice if…

      • Nothing stands out - its ratings have no weak spot for its class.

      Questions5
      What is the SEER2 rating of the Friedrich RD18AY24AJVC?
      The Friedrich RD18AY24AJVC is rated at up to 19.0 SEER2 and 11.7 EER2 for cooling and up to 10.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 399 certified matchups SEER2 ranges from 17.0-19.0.
      Is the Friedrich RD18AY24AJVC good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 18,400 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 RD18AY24AJVC cost to run per year?
      At its rated efficiency it costs about $519-$1,338 a year in electricity in large U.S. cities, depending on climate and local rates - for example $633 in Phoenix and $1,113 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 Friedrich RD18AY24AJVC?
      ENERGY STAR lists 399 certified combinations for this outdoor unit. The highest-rated ones use RCFY2417STANM, SH2VY2417STACN, RH2VY2417STACN.
      What refrigerant does the Friedrich RD18AY24AJVC 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.
