Heating and cooling by outdoor temperature

Certified heating at 5, 17, and 47°F and cooling at 95°F for NTXSKH15A112AA, by outdoor temperature Heating: 7,000 Btu/h at 5°F, 9,700 Btu/h at 17°F, 16,400 Btu/h at 47°F. Cooling: 13,700 Btu/h at 95°F. The bars start at zero. Median of 15,000 Btu mini-split models: 14,000 Btu/h at 5°F, 12,000 Btu/h at 17°F, 16,000 Btu/h at 47°F, 15,000 Btu/h at 95°F. 0 5,000 10,000 15,000 20,000 Btu/h 7,000 5°F 9,700 17°F 16,400 47°F 13,700 95°F Outdoor temperature (°F)

This pairing delivers 16,400 Btu/h of heat at 47°F, 9,700 Btu/h at 17°F, and 7,000 Btu/h at 5°F, 43% of its 47°F rating. It delivers 13,700 Btu/h of cooling at 95°F. At 5°F that is 7,000 Btu/h short of the example heating load of 14,000 Btu/h; at 95°F it is 6,700 Btu/h above the example cooling load of 7,000 Btu/h.

Each bar is a separate certified test, drawn at its outdoor temperature, starting at zero. The 47°F figure is at normal speed; the 17 and 5°F figures are at full speed. The short dark line on each bar is the median of 15,000 Btu mini-split models, one value per model. The shaded 17 to 45°F band is the frosting range: the outdoor coil can frost, and the unit pauses to defrost.

The dashed lines are example loads for a typical area of about 600 sq ft where winters reach 5°F: heating runs from 14,000 Btu/h at 5°F to 0 at 65°F, and cooling runs from 0 at 65°F to 7,000 Btu/h at 95°F, at 1,000 sq ft per ton. A house in a hot climate or with large west-facing windows can need twice as much cooling. They are examples, not your building.

This unit is above 3% of them, at number 95 of 98 by heat at 5°F. The middle half of the group runs 12,300 to 17,500 Btu/h.

This size class is defined by cooling capacity, so cooling is not compared here.

Among 15,000 Btu mini-split models, each by its median certified pairing, highest first: 5°F output as a share of its 47°F rating, 82nd of 98; HSPF2, 104th of 104. Models without that figure are left out.

Similar ratings at 47°F

These mini-split models share the nominal cooling size. Comparisons use each model’s median certified figures across pairings.

  • SUZ-KA15NAHZ: The same 16,400 Btu/h rating at 47°F; 16,400 Btu/h at 5°F (this model: 7,000).
  • SUZ-KA15NA2: The same 16,400 Btu/h rating at 47°F; 9,400 Btu/h at 5°F (this model: 7,000).
  • MUZ-FX15NLHZ: 16,500 Btu/h at 47°F (this model: 16,400); 22,200 Btu/h at 5°F (this model: 7,000).

Floor area at the cold test point

The median certified output of 7,000 Btu/h at 5°F matches the size calculator’s heating estimate for these floor areas, rounded to about 10 sq ft. Each range divides that output by the climate band’s heating rates.

This is an estimate, not a house-specific load calculation. Output stays at the 5°F test point for every band; it does not predict output at the band’s winter design temperature.
