A good fit if…

  • You want a choice of indoor units - 42 certified pairings.

Think twice if…

  • You often see nights below 0°F - it is not cold-climate certified.
  • Cooling cost matters most - its SEER2 is below average for central heat pumps.
  • You mainly need heat - its HSPF2 is below average for central heat pumps.
  • Comfort and noise matter - a single-stage compressor runs only full-on or off.

Questions5
What is the SEER2 rating of the GE NS16H42SA5-**A?
The GE NS16H42SA5-**A is rated at up to 15.5 SEER2 and 13.2 EER2 for cooling and up to 8.2 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 42 certified matchups SEER2 ranges from 15.2-15.5.
Is the GE NS16H42SA5-**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 3.5-ton model.
How much does the GE NS16H42SA5-**A cost to run per year?
At its rated efficiency it costs about $1,254-$3,104 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,512 in Phoenix and $2,567 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 GE NS16H42SA5-**A?
ENERGY STAR lists 42 certified combinations for this outdoor unit. The highest-rated ones use NCU[C,U]49CT5*-**+TDR, NCU[C,U]48CT5*-**+TDR, NAM42V1TA5*-.
What refrigerant does the GE NS16H42SA5-**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.
