This pairing delivers 42,000 Btu/h of heat at 47°F, 26,400 Btu/h at 17°F, and 29,000 Btu/h at 5°F, 69% of its 47°F rating. It delivers 36,000 Btu/h of cooling at 95°F. At 5°F that is 2,000 Btu/h short of the example heating load of 31,000 Btu/h; at 95°F it is 20,500 Btu/h above the example cooling load of 15,500 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 3-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 1,300 sq ft where winters reach 5°F: heating runs from 31,000 Btu/h at 5°F to 0 at 65°F, and cooling runs from 0 at 65°F to 15,500 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.

How it compares with other 36,000 Btu heat pumps

3-ton mini-split models

This pairing at 5°F: 29,000 Btu/h
This unit at 5°F median across its pairings: 29,000 Btu/h
Median of 3-ton mini-split models at 5°F: 31,000 Btu/h
Models in this group: 553

This unit is above 43% of them, at number 315 of 553 by heat at 5°F. The middle half of the group runs 26,000 to 36,000 Btu/h.

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

Among 36,000 Btu mini-split models, each by its median certified pairing, highest first: 5°F output as a share of its 47°F rating, 496th of 551; HSPF2, 291st of 553 (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.

PUZ-A36NKA7: The same 42,000 Btu/h rating at 47°F; 14,000 Btu/h at 5°F (this model: 29,000).
PUMY-HL36NKMU: The same 42,000 Btu/h rating at 47°F; 42,000 Btu/h at 5°F (this model: 29,000).
AOUK036MSAN7: The same 42,000 Btu/h rating at 47°F; 40,500 Btu/h at 5°F (this model: 29,000).

Floor area at the cold test point

The median certified output of 29,000 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.

Floor area by climate band and house condition
Climate band	House condition	Btu/h per sq ft	Approximate sq ft
Mild	Drafty, little insulation	24–42	690–1,210
Mild	Typical	16–26	1,120–1,810
Mild	Tight, well insulated	10–18	1,610–2,900
Cold	Drafty, little insulation	28–52	560–1,040
Cold	Typical	18–30	970–1,610
Cold	Tight, well insulated	12–22	1,320–2,420
Very cold	Drafty, little insulation	32–58	500–910
Very cold	Typical	22–38	760–1,320
Very cold	Tight, well insulated	16–28	1,040–1,810

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.
