      Questions5
      What is the SEER2 rating of the Armstrong Air A7SCP18V24P-**A?
      The Armstrong Air A7SCP18V24P-**A is rated at up to 18.5 SEER2 and 12.3 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 268 certified matchups SEER2 ranges from 15.2-18.5.
      Is the Armstrong Air A7SCP18V24P-**A good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 23,400 BTU/h at 5°F with a COP of 1.85, so it is still 1.9 times as efficient as electric resistance heat at that temperature.
      How much does the Armstrong Air A7SCP18V24P-**A cost to run per year?
      At its rated efficiency it costs about $608-$1,538 a year in electricity in large U.S. cities, depending on climate and local rates - for example $738 in Phoenix and $1,275 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 Armstrong Air A7SCP18V24P-**A?
      ENERGY STAR lists 268 certified combinations for this outdoor unit. The highest-rated ones use 7AH2AE30PX-, 7AH1AV24PX-, 7AH2AV30PXC-.
      What refrigerant does the Armstrong Air A7SCP18V24P-**A 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.
