Heating and cooling by outdoor temperature
This pairing delivers 24,000 Btu/h7.03 kW of heat at 47°F, 20,000 Btu/h5.86 kW at 17°F, and 21,000 Btu/h6.15 kW at 5°F, 88% of its 47°F rating. It delivers 24,000 Btu/h7.03 kW of cooling at 95°F. At 5°F that is 2,000 Btu/h0.59 kW above the example heating load of 19,000 Btu/h5.57 kW; at 95°F it is 14,500 Btu/h4.25 kW above the example cooling load of 9,500 Btu/h2.78 kW.
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/h5.57 kW at 5°F to 0 at 65°F, and cooling runs from 0 at 65°F to 9,500 Btu/h2.78 kW 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.
