Heating and cooling by outdoor temperature

Certified heating at 5, 17, and 47°F and cooling at 95°F for RD18AY24AJVC, by outdoor temperature Heating: 17,000 Btu/h at 5°F, 18,200 Btu/h at 17°F, 20,800 Btu/h at 47°F. Cooling: 21,000 Btu/h at 95°F. The bars start at zero. Median of 1.5-ton central models: 11,200 Btu/h at 5°F, 12,600 Btu/h at 17°F, 18,000 Btu/h at 47°F, 18,000 Btu/h at 95°F. 0 5,000 10,000 15,000 20,000 25,000 Btu/h 17,000 5°F 18,200 17°F 20,800 47°F 21,000 95°F Outdoor temperature (°F)

This pairing delivers 20,800 Btu/h of heat at 47°F, 18,200 Btu/h at 17°F, and 17,000 Btu/h at 5°F, 82% of its 47°F rating. It delivers 21,000 Btu/h of cooling at 95°F. At 5°F that is 6,000 Btu/h above the example heating load of 11,000 Btu/h; at 95°F it is 15,500 Btu/h above the example cooling load of 5,500 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 1.5-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 450 sq ft where winters reach 5°F: heating runs from 11,000 Btu/h at 5°F to 0 at 65°F, and cooling runs from 0 at 65°F to 5,500 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 71% of them, at number 71 of 243 by heat at 5°F. The middle half of the group runs 8,600 to 18,000 Btu/h.

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

Among 18,000 Btu central models, each by its median certified pairing, highest first: 5°F output as a share of its 47°F rating, 95th of 243; HSPF2, 32nd of 254 (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.

  • GHO18H52ACXL05: 22,000 Btu/h at 47°F (this model: 21,000); 20,400 Btu/h at 5°F (this model: 17,000).
  • 5HPL5024A1: 22,000 Btu/h at 47°F (this model: 21,000); 19,000 Btu/h at 5°F (this model: 17,000).

Floor area at the cold test point

The median certified output of 17,000 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.

What affects the price

We don't have prices. These things drive the cost.

  • The size of the unit, and the indoor equipment on the same certificate.
  • Whether existing ductwork is reused, altered, or replaced.
  • The electrical work: a circuit, a disconnect, and sometimes a panel change.
  • 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.
