      Questions5
      What is the SEER2 rating of the Ruud UP19AY36AJVC?
      The Ruud UP19AY36AJVC is rated at up to 21.0 SEER2 and 12.0 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 27 certified matchups SEER2 ranges from 19.0-21.0.
      Is the Ruud UP19AY36AJVC good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 29,600 BTU/h at 5°F with a COP of 2.20, so it is still 2.2 times as efficient as electric resistance heat at that temperature.
      How much does the Ruud UP19AY36AJVC cost to run per year?
      At its rated efficiency it costs about $767-$2,138 a year in electricity in large U.S. cities, depending on climate and local rates - for example $957 in Phoenix and $1,796 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 Ruud UP19AY36AJVC?
      ENERGY STAR lists 27 certified combinations for this outdoor unit. The highest-rated ones use RCFY3621MEAAM, RHMVY3621MEACA.
      What refrigerant does the Ruud UP19AY36AJVC use?

      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.
