Heating and cooling by outdoor temperature
This pairing delivers 24,000 Btu/h7.03 kW of heat at 47°F, 18,000 Btu/h5.28 kW at 17°F, and 24,000 Btu/h7.03 kW at 5°F, 100% of its 47°F rating. It delivers 24,000 Btu/h7.03 kW of cooling at 95°F. At 5°F that is 5,000 Btu/h1.47 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 mini-split 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.

Floor area at the cold test point
The median certified output of 24,000 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 | 570–1,000 |
| Mild | Typical | 16–26 | 920–1,500 |
| Mild | Tight, well insulated | 10–18 | 1,330–2,400 |
| Cold | Drafty, little insulation | 28–52 | 460–860 |
| Cold | Typical | 18–30 | 800–1,330 |
| Cold | Tight, well insulated | 12–22 | 1,090–2,000 |
| Very cold | Drafty, little insulation | 32–58 | 410–750 |
| Very cold | Typical | 22–38 | 630–1,090 |
| Very cold | Tight, well insulated | 16–28 | 860–1,500 |
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.

Sold as, and units with identical certified values
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.
