      Questions5
      What is the SEER2 rating of the ECOER ERDA19H-60AB?
      The ECOER ERDA19H-60AB is rated at up to 19.0 SEER2 and 11.2 EER2 for cooling and up to 9.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the ECOER ERDA19H-60AB good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 39,500 BTU/h at 5°F with a COP of 1.90, so it is still 1.9 times as efficient as electric resistance heat at that temperature.
      How much does the ECOER ERDA19H-60AB cost to run per year?
      At its rated efficiency it costs about $1,385-$3,720 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,710 in Phoenix and $3,109 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the ECOER ERDA19H-60AB the same as the YISO YRHA1-60AB?
      Yes, as far as the certified ratings go. ENERGY STAR lists both model numbers with identical efficiency, capacity and matchups, which means the same outdoor unit sold under a different brand or with a minor variant code (voltage, colour or region). The full list is on this page.
      What refrigerant does the ECOER ERDA19H-60AB 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.
