Heating and cooling by outdoor temperature
This pairing delivers 24,000 Btu/h7.03 kW of heat at 47°F and 14,100 Btu/h4.13 kW at 17°F. It delivers 22,000 Btu/h6.45 kW of cooling at 95°F. At 95°F that is 12,500 Btu/h3.66 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.

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.

Field definitions
- COP
- Heat delivered for each unit of electricity used. A COP of 2.5 gives 2.5 times the heat of an electric baseboard heater.
- HSPF2
- 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
- Heat output at 5°F as a percentage of the 47°F rating.
- % of rating at 17°F
- Heat output at 17°F as a percentage of the 47°F rating.
