Heating and cooling by outdoor temperature

Certified heating at 5, 17, and 47°F and cooling at 95°F for HH824E2S11, by outdoor temperature Heating: 18,500 Btu/h at 5°F, 18,200 Btu/h at 17°F, 23,000 Btu/h at 47°F. Cooling: 23,000 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 18,500 5°F 18,200 17°F 23,000 47°F 23,000 95°F Outdoor temperature (°F)

This pairing delivers 23,000 Btu/h of heat at 47°F, 18,200 Btu/h at 17°F, and 18,500 Btu/h at 5°F, 80% of its 47°F rating. It delivers 23,000 Btu/h of cooling at 95°F. At 5°F that is 500 Btu/h short of the example heating load of 19,000 Btu/h; at 95°F it is 13,500 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 normal speed; 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.

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.
