This pairing delivers 30,000 Btu/h of heat at 47°F, 27,600 Btu/h at 17°F, and 26,400 Btu/h at 5°F, 88% of its 47°F rating. It delivers 28,400 Btu/h of cooling at 95°F. At 5°F that is 1,400 Btu/h above the example heating load of 25,000 Btu/h; at 95°F it is 15,900 Btu/h above the example cooling load of 12,500 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 2.5-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 1,050 sq ft where winters reach 5°F: heating runs from 25,000 Btu/h at 5°F to 0 at 65°F, and cooling runs from 0 at 65°F to 12,500 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 30,000 Btu heat pumps

2.5-ton mini-split models

This pairing at 5°F: 26,400 Btu/h
This unit at 5°F median across its pairings: 26,400 Btu/h
Median of 2.5-ton mini-split models at 5°F: 25,000 Btu/h
Models in this group: 405

This unit is above 57% of them, at number 173 of 405 by heat at 5°F. The middle half of the group runs 20,000 to 27,000 Btu/h.

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

Among 30,000 Btu mini-split models, each by its median certified pairing, highest first: 5°F output as a share of its 47°F rating, 180th of 405 (tied); HSPF2, 275th of 405 (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.

AOD30-30HFN1-MS0W: The same 30,000 Btu/h rating at 47°F; 17,500 Btu/h at 5°F (this model: 26,400).
ADSZ130DA: The same 30,000 Btu/h rating at 47°F; 18,000 Btu/h at 5°F (this model: 26,400).
MOD-30HFN1CA: The same 30,000 Btu/h rating at 47°F; 18,400 Btu/h at 5°F (this model: 26,400).

Floor area at the cold test point

The median certified output of 26,400 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	630–1,100
Mild	Typical	16–26	1,020–1,650
Mild	Tight, well insulated	10–18	1,470–2,640
Cold	Drafty, little insulation	28–52	510–940
Cold	Typical	18–30	880–1,470
Cold	Tight, well insulated	12–22	1,200–2,200
Very cold	Drafty, little insulation	32–58	460–830
Very cold	Typical	22–38	690–1,200
Very cold	Tight, well insulated	16–28	940–1,650

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.
