Heating and cooling by outdoor temperature

Certified heating at 5, 17, and 47°F and cooling at 95°F for H4H7T24*K*AAA*, by outdoor temperature Heating: no certified figure at 5°F, 14,100 Btu/h at 17°F, 23,800 Btu/h at 47°F. Cooling: 23,800 Btu/h at 95°F. The bars start at zero. Median of 2-ton central models: 19,000 Btu/h at 5°F, 19,200 Btu/h at 17°F, 24,000 Btu/h at 47°F, 24,000 Btu/h at 95°F. 0 5,000 10,000 15,000 20,000 25,000 Btu/h NR 5°F 14,100 17°F 23,800 47°F 23,800 95°F Outdoor temperature (°F)

This pairing delivers 23,800 Btu/h of heat at 47°F and 14,100 Btu/h at 17°F. It delivers 23,800 Btu/h of cooling at 95°F. At 95°F that is 14,300 Btu/h above the example cooling load of 9,500 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 2-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 800 sq ft where winters reach 5°F: heating runs from 19,000 Btu/h at 5°F to 0 at 65°F, and cooling runs from 0 at 65°F to 9,500 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 size class is defined by cooling capacity, so cooling is not compared here.

Among 24,000 Btu central models, each by its median certified pairing, highest first: HSPF2, 442nd of 578 (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.

  • 50VR-K24---30: The same 23,800 Btu/h rating at 47°F; HSPF2 7.2 (this model: 8.1).
  • VUH24-VA6BA(O): 24,000 Btu/h at 47°F (this model: 23,800); HSPF2 11.0 (this model: 8.1).

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.

Heating efficiency over a typical season. Higher uses less electricity.
SEER2
Cooling efficiency over a typical season. Higher uses less electricity.
EER2
Cooling output divided by electrical input in the 95°F full-load test, in Btu/h per watt.
Cold output
