      A good fit if…

      • You want low cooling bills - its SEER2 beats 93% of mini-splits.
      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 8,000 BTU/h at 5°F.
      • It will heat most of the year - its HSPF2 beats 97% of mini-splits.
      • You want steady temperatures and quiet running - the compressor varies its speed.

      Think twice if…

      • You want the newest refrigerant - it uses R-410A, which is being phased down.

      Questions5
      What is the SEER2 rating of the Comfortmaker DLCSRBH06AAK?
      The Comfortmaker DLCSRBH06AAK is rated at up to 26.5 SEER2 and 15.8 EER2 for cooling and up to 13.6 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 48 certified matchups SEER2 ranges from 22.0-26.5.
      Is the Comfortmaker DLCSRBH06AAK good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 8,000 BTU/h at 5°F with a COP of 2.10, so it is still 2.1 times as efficient as electric resistance heat at that temperature.
      How much does the Comfortmaker DLCSRBH06AAK cost to run per year?
      At its rated efficiency it costs about $107-$317 a year in electricity in large U.S. cities, depending on climate and local rates - for example $136 in Phoenix and $268 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 Comfortmaker DLCSRBH06AAK?
      ENERGY STAR lists 48 certified combinations for this outdoor unit. The highest-rated ones use COMFORTMAKER DLFSHCH06XAK, ARCOAIRE DLFSHCH06XAK, AIRQUEST DLFSHCH06XAK.
      What refrigerant does the Comfortmaker DLCSRBH06AAK use?
      It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and R-32.

      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.
