This pairing delivers 46,500 Btu/h of heat at 47°F, 30,400 Btu/h at 17°F, and 26,000 Btu/h at 5°F, 56% of its 47°F rating. It delivers 46,500 Btu/h of cooling at 95°F. At 5°F that is 10,500 Btu/h short of the example heating load of 36,500 Btu/h; at 95°F it is 28,500 Btu/h above the example cooling load of 18,000 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 4-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 1,500 sq ft where winters reach 5°F: heating runs from 36,500 Btu/h at 5°F to 0 at 65°F, and cooling runs from 0 at 65°F to 18,000 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.

How it compares with other 48,000 Btu heat pumps

4-ton central models

This pairing at 5°F: 26,000 Btu/h
This unit at 5°F median across its pairings: 26,000 Btu/h
Median of 4-ton central models at 5°F: 36,400 Btu/h
Models in this group: 408

This unit is above 25% of them, at number 305 of 408 by heat at 5°F. The middle half of the group runs 25,350 to 46,000 Btu/h.

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

Among 48,000 Btu central models, each by its median certified pairing, highest first: 5°F output as a share of its 47°F rating, 304th of 408; HSPF2, 368th of 420 (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.

GZV7SA4810A: The same 46,500 Btu/h rating at 47°F; 33,600 Btu/h at 5°F (this model: 26,000).

Floor area at the cold test point

The median certified output of 26,000 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	620–1,080
Mild	Typical	16–26	1,000–1,630
Mild	Tight, well insulated	10–18	1,440–2,600
Cold	Drafty, little insulation	28–52	500–930
Cold	Typical	18–30	870–1,440
Cold	Tight, well insulated	12–22	1,180–2,170
Very cold	Drafty, little insulation	32–58	450–810
Very cold	Typical	22–38	680–1,180
Very cold	Tight, well insulated	16–28	930–1,630

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.
