Heating and cooling by outdoor temperature
This pairing delivers 34,200 Btu/h10.02 kW of heat at 47°F, 33,200 Btu/h9.73 kW at 17°F, and 18,500 Btu/h5.42 kW at 5°F, 54% of its 47°F rating. It delivers 34,200 Btu/h10.02 kW of cooling at 95°F. At 5°F that is 8,000 Btu/h2.34 kW short of the example heating load of 26,500 Btu/h7.77 kW; at 95°F it is 21,200 Btu/h6.21 kW above the example cooling load of 13,000 Btu/h3.81 kW.
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 3-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 1,100 sq ft where winters reach 5°F: heating runs from 26,500 Btu/h7.77 kW at 5°F to 0 at 65°F, and cooling runs from 0 at 65°F to 13,000 Btu/h3.81 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.

Floor area at the cold test point
The median certified output of 18,500 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.
| Climate band | House condition | Btu/h per sq ft | Approximate sq ft |
|---|---|---|---|
| Mild | Drafty, little insulation | 24–42 | 440–770 |
| Mild | Typical | 16–26 | 710–1,160 |
| Mild | Tight, well insulated | 10–18 | 1,030–1,850 |
| Cold | Drafty, little insulation | 28–52 | 360–660 |
| Cold | Typical | 18–30 | 620–1,030 |
| Cold | Tight, well insulated | 12–22 | 840–1,540 |
| Very cold | Drafty, little insulation | 32–58 | 320–580 |
| Very cold | Typical | 22–38 | 490–840 |
| Very cold | Tight, well insulated | 16–28 | 660–1,160 |
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.
