Heating and cooling by outdoor temperature

Certified heating at 5, 17, and 47°F and cooling at 95°F for RD17AZ36AJ3N, by outdoor temperature Heating: 29,400 Btu/h at 5°F, 31,200 Btu/h at 17°F, 36,000 Btu/h at 47°F. Cooling: 34,200 Btu/h at 95°F. The bars start at zero. Median of 3-ton central models: 26,400 Btu/h at 5°F, 26,200 Btu/h at 17°F, 35,200 Btu/h at 47°F, 35,000 Btu/h at 95°F. 0 10,000 20,000 30,000 40,000 Btu/h 29,400 5°F 31,200 17°F 36,000 47°F 34,200 95°F Outdoor temperature (°F)

This pairing delivers 36,000 Btu/h of heat at 47°F, 31,200 Btu/h at 17°F, and 29,400 Btu/h at 5°F, 82% of its 47°F rating. It delivers 34,200 Btu/h of cooling at 95°F. At 5°F that is 2,900 Btu/h above the example heating load of 26,500 Btu/h; at 95°F it is 21,200 Btu/h above the example cooling load of 13,000 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 3-ton central 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 1,100 sq ft where winters reach 5°F: heating runs from 26,500 Btu/h at 5°F to 0 at 65°F, and cooling runs from 0 at 65°F to 13,000 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.

451

This unit is above 63% of them, at number 169 of 451 by heat at 5°F. The middle half of the group runs 18,650 to 32,000 Btu/h.

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

Among 36,000 Btu central models, each by its median certified pairing, highest first: 5°F output as a share of its 47°F rating, 166th of 451; HSPF2, 313th of 467 (tied). Models without that figure are left out.

Similar ratings at 47°F

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

  • FOP1836MJAZCA: The same 36,000 Btu/h rating at 47°F; 43,000 Btu/h at 5°F (this model: 29,400).
  • AHU3G-36HFN-B: The same 36,000 Btu/h rating at 47°F; 32,600 Btu/h at 5°F (this model: 29,400).
  • MOE30-36HFN10-M3X: The same 36,000 Btu/h rating at 47°F; 36,000 Btu/h at 5°F (this model: 29,400).

Floor area at the cold test point

The median certified output of 29,400 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.

  • Refrigerant line length and how the outdoor unit is mounted.
  • Permits and inspection, which vary by municipality.
  • Removing and disposing of the old equipment.
  • Local labor rates and how busy the season is.
  • Rebates and tax credits, which change and have deadlines.
