Heating and cooling by outdoor temperature

Certified heating at 5, 17, and 47°F and cooling at 95°F for C5H8T60*K*AAA*, by outdoor temperature Heating: 30,200 Btu/h at 5°F, 36,800 Btu/h at 17°F, 57,500 Btu/h at 47°F. Cooling: 55,500 Btu/h at 95°F. The bars start at zero. Median of 4.5-ton central models: 40,000 Btu/h at 5°F, 37,800 Btu/h at 17°F, 56,000 Btu/h at 47°F, 55,000 Btu/h at 95°F. 0 20,000 40,000 60,000 80,000 Btu/h 30,200 5°F 36,800 17°F 57,500 47°F 55,500 95°F Outdoor temperature (°F)

This pairing delivers 57,500 Btu/h of heat at 47°F, 36,800 Btu/h at 17°F, and 30,200 Btu/h at 5°F, 53% of its 47°F rating. It delivers 55,500 Btu/h of cooling at 95°F. At 5°F that is 9,800 Btu/h short of the example heating load of 40,000 Btu/h; at 95°F it is 35,500 Btu/h above the example cooling load of 20,000 Btu/h.

Each bar is a separate certified test, drawn at its outdoor temperature, starting at zero. The 47°F figure is at high stage; the 17 and 5°F figures are at full speed. The short dark line on each bar is the median of 4.5-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 1,650 sq ft where winters reach 5°F: heating runs from 40,000 Btu/h at 5°F to 0 at 65°F, and cooling runs from 0 at 65°F to 20,000 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.

343

This unit is above 17% of them, at number 286 of 343 by heat at 5°F. The middle half of the group runs 32,000 to 45,000 Btu/h.

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

Among 54,000 Btu central models, each by its median certified pairing, highest first: 5°F output as a share of its 47°F rating, 289th of 343 (tied); HSPF2, 291st of 358 (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.

  • MDPH18060D: 57,000 Btu/h at 47°F (this model: 57,500); 51,000 Btu/h at 5°F (this model: 30,200).

Floor area at the cold test point

The median certified output of 30,200 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.
