      A good fit if…

      • You want steady temperatures and quiet running - the compressor varies its speed.

      Think twice if…

      • You often see nights below 0°F - it is not cold-climate certified.
      • You mainly need heat - its HSPF2 is below average for mini-splits.
      • You want the newest refrigerant - it uses R-410A, which is being phased down.

      Questions6
      What is the SEER2 rating of the Comfort-Aire A-DVH09SH-1?
      The Comfort-Aire A-DVH09SH-1 is rated at up to 21.7 SEER2 and 12.6 EER2 for cooling and up to 9.1 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
      Is the Comfort-Aire A-DVH09SH-1 good for cold climates?
      It is not cold-climate certified: none of its matchups meet the ENERGY STAR cold-climate criteria (a COP of at least 1.75 at 5°F among other limits). In places with frequent sub-zero nights, pick a cold-climate 9,000 BTU model.
      How much does the Comfort-Aire A-DVH09SH-1 cost to run per year?
      At its rated efficiency it costs about $197-$661 a year in electricity in large U.S. cities, depending on climate and local rates - for example $261 in Phoenix and $567 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the Comfort-Aire A-DVH09SH-1 the same as the ECO AC EHS-O09BB?
      Yes, as far as the certified ratings go. ENERGY STAR lists 3 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.
      Which indoor units work with the Comfort-Aire A-DVH09SH-1?
      ENERGY STAR lists 2 certified combinations for this outdoor unit. The highest-rated ones use COMFORT-AIRE B-DVH09SH-1, Comfort Aire B-DVH09SH-1.
      What refrigerant does the Comfort-Aire A-DVH09SH-1 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.
