      A good fit if…

      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 32,600 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.
      • You want a choice of indoor units - 10 certified pairings.

      Think twice if…

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

      Questions5
      What is the SEER2 rating of the ECO-AIR ECUO-30H?
      The ECO-AIR ECUO-30H is rated at up to 16.8 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 10 certified matchups SEER2 ranges from 15.3-16.8.
      Is the ECO-AIR ECUO-30H good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 32,600 BTU/h at 5°F with a COP of 1.96, so it is still 2.0 times as efficient as electric resistance heat at that temperature.
      How much does the ECO-AIR ECUO-30H cost to run per year?
      At its rated efficiency it costs about $809-$1,999 a year in electricity in large U.S. cities, depending on climate and local rates - for example $974 in Phoenix and $1,652 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 ECO-AIR ECUO-30H?
      ENERGY STAR lists 10 certified combinations for this outdoor unit. The highest-rated ones use ECMP-30U, ECCB-36U, ECCC-36U.
      What refrigerant does the ECO-AIR ECUO-30H 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.
