This pairing delivers 17,100 Btu/h of heat at 47°F, 10,900 Btu/h at 17°F, and 8,200 Btu/h at 5°F, 48% of its 47°F rating. It delivers 17,100 Btu/h of cooling at 95°F. At 5°F that is 2,800 Btu/h short of the example heating load of 11,000 Btu/h; at 95°F it is 11,600 Btu/h above the example cooling load of 5,500 Btu/h.

Each bar is a separate certified test, drawn at its outdoor temperature, starting at zero. The 47°F figure is at high stage; the 17 and 5°F figures are at full speed. The short dark line on each bar is the median of 1.5-ton central 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 450 sq ft where winters reach 5°F: heating runs from 11,000 Btu/h at 5°F to 0 at 65°F, and cooling runs from 0 at 65°F to 5,500 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 18,000 Btu heat pumps

1.5-ton central models

This pairing at 5°F: 8,200 Btu/h
This unit at 5°F median across its pairings: 8,200 Btu/h
Median of 1.5-ton central models at 5°F: 11,200 Btu/h
Models in this group: 243

This unit is above 8% of them, at number 224 of 243 by heat at 5°F. The middle half of the group runs 8,600 to 18,000 Btu/h.

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

Among 18,000 Btu central models, each by its median certified pairing, highest first: 5°F output as a share of its 47°F rating, 202nd of 243 (tied); HSPF2, 191st of 254 (tied). Models without that figure are left out.

Similar ratings at 47°F

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

FRP15AZ18AJ2N: The same 17,100 Btu/h rating at 47°F; 9,300 Btu/h at 5°F (this model: 8,200).
FOP1518TJAZNA: The same 17,100 Btu/h rating at 47°F; 9,200 Btu/h at 5°F (this model: 8,200).
FXU12HP230V1R32AO: 17,000 Btu/h at 47°F (this model: 17,100); 17,000 Btu/h at 5°F (this model: 8,200).

Floor area at the cold test point

The median certified output of 8,200 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	200–340
Mild	Typical	16–26	320–510
Mild	Tight, well insulated	10–18	460–820
Cold	Drafty, little insulation	28–52	160–290
Cold	Typical	18–30	270–460
Cold	Tight, well insulated	12–22	370–680
Very cold	Drafty, little insulation	32–58	140–260
Very cold	Typical	22–38	220–370
Very cold	Tight, well insulated	16–28	290–510

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.
