      1.5-ton central heat pump · 4SHP17LE SERIES

      Armstrong Air 4SHP17LE118P-**A

      Average cooling efficiency and below average heating efficiency for a 1.5-ton central heat pump, but not rated for cold climates.

      Ranks #75 of 170 1.5 ton central heat pumps for cooling efficiency, and costs about $549 a year to run in a mixed climate like Atlanta.

      A good fit if…

      • You want a choice of indoor units - 662 certified pairings.

      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 central heat pumps.
      • You want the newest refrigerant - it uses R-410A, which is being phased down.
      • Comfort and noise matter - a single-stage compressor runs only full-on or off.

      Questions5
      What is the SEER2 rating of the Armstrong Air 4SHP17LE118P-**A?
      The Armstrong Air 4SHP17LE118P-**A is rated at up to 16.8 SEER2 and 14.0 EER2 for cooling and up to 8.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 662 certified matchups SEER2 ranges from 15.2-16.8.
      Is the Armstrong Air 4SHP17LE118P-**A 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 1.5-ton model.
      How much does the Armstrong Air 4SHP17LE118P-**A cost to run per year?
      At its rated efficiency it costs about $503-$1,303 a year in electricity in large U.S. cities, depending on climate and local rates - for example $614 in Phoenix and $1,084 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 4SHP17LE118P-**A?
      ENERGY STAR lists 662 certified combinations for this outdoor unit. The highest-rated ones use EA(C;U)1P30B+TDR+TXV, EA(C;U)1P30A+TDR+TXV, EAC4X30B+TDR.
      What refrigerant does the Armstrong Air 4SHP17LE118P-**A 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.
