Heating and cooling by outdoor temperature

Certified heating at 5, 17, and 47°F and cooling at 95°F for 1G12CB1BE, by outdoor temperature Heating: 9,100 Btu/h at 5°F, 7,800 Btu/h at 17°F, 11,500 Btu/h at 47°F. Cooling: 11,500 Btu/h at 95°F. The bars start at zero. Median of 1-ton mini-split models: 9,200 Btu/h at 5°F, 9,800 Btu/h at 17°F, 12,000 Btu/h at 47°F, 12,000 Btu/h at 95°F. 0 2,500 5,000 7,500 10,000 12,500 Btu/h 9,100 5°F 7,800 17°F 11,500 47°F 11,500 95°F Outdoor temperature (°F)

This pairing delivers 11,500 Btu/h of heat at 47°F, 7,800 Btu/h at 17°F, and 9,100 Btu/h at 5°F, 79% of its 47°F rating. It delivers 11,500 Btu/h of cooling at 95°F. At 5°F that is 100 Btu/h above the example heating load of 9,000 Btu/h; at 95°F it is 6,500 Btu/h above the example cooling load of 5,000 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 1-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 400 sq ft where winters reach 5°F: heating runs from 9,000 Btu/h at 5°F to 0 at 65°F, and cooling runs from 0 at 65°F to 5,000 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.
