Heating and cooling by outdoor temperature

Certified heating at 5, 17, and 47°F and cooling at 95°F for MUZ-JP09WA, by outdoor temperature Heating: no certified figure at 5°F, 6,700 Btu/h at 17°F, 10,900 Btu/h at 47°F. Cooling: 9,000 Btu/h at 95°F. The bars start at zero. Median of 9,000 Btu mini-split models: 7,700 Btu/h at 5°F, 8,000 Btu/h at 17°F, 10,000 Btu/h at 47°F, 9,000 Btu/h at 95°F. 0 2,500 5,000 7,500 10,000 12,500 Btu/h NR 5°F 6,700 17°F 10,900 47°F 9,000 95°F Outdoor temperature (°F)

This pairing delivers 10,900 Btu/h of heat at 47°F and 6,700 Btu/h at 17°F. It delivers 9,000 Btu/h of cooling at 95°F. At 95°F that is 5,500 Btu/h above the example cooling load of 3,500 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 9,000 Btu 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 300 sq ft where winters reach 5°F: heating runs from 7,500 Btu/h at 5°F to 0 at 65°F, and cooling runs from 0 at 65°F to 3,500 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.

This size class is defined by cooling capacity, so cooling is not compared here.

Among 9,000 Btu mini-split models, each by its median certified pairing, highest first: HSPF2, 394th of 909 (tied). Models without that figure are left out.

Similar ratings at 47°F

These mini-split models share the nominal cooling size. Comparisons use each model’s median certified figures across pairings.

  • 4C28SCH09H21: The same 10,900 Btu/h rating at 47°F; HSPF2 12.5 (this model: 10.0).

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.

Product history
