A good fit if…

  • You want low cooling bills - its SEER2 beats 85% of central heat pumps.
  • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 30,800 BTU/h at 5°F.
  • It will heat most of the year - its HSPF2 beats 76% of central heat pumps.
  • You want steady temperatures and quiet running - the compressor varies its speed.

Think twice if…

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

Questions5
What is the SEER2 rating of the Armstrong Air A7SCP18V36P-**A?
The Armstrong Air A7SCP18V36P-**A is rated at up to 19.0 SEER2 and 11.7 EER2 for cooling and up to 9.6 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 432 certified matchups SEER2 ranges from 15.2-19.0.
Is the Armstrong Air A7SCP18V36P-**A good for cold climates?
Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 30,800 BTU/h at 5°F with a COP of 1.95, so it is still 2.0 times as efficient as electric resistance heat at that temperature.
How much does the Armstrong Air A7SCP18V36P-**A cost to run per year?
At its rated efficiency it costs about $852-$2,329 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,057 in Phoenix and $1,952 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 A7SCP18V36P-**A?
ENERGY STAR lists 432 certified combinations for this outdoor unit. The highest-rated ones use 7AH2AV42PXC-, 7EH36CX-**+TDR, 7E[C,U]36BX-**+TDR.
What refrigerant does the Armstrong Air A7SCP18V36P-**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.
