This pairing delivers 34,400 Btu/h of heat at 47°F, 20,000 Btu/h at 17°F, and 17,600 Btu/h at 5°F, 51% of its 47°F rating. It delivers 34,200 Btu/h of cooling at 95°F. At 5°F that is 8,900 Btu/h short of the example heating load of 26,500 Btu/h; at 95°F it is 21,200 Btu/h above the example cooling load of 13,000 Btu/h.

Each bar is a separate certified test, drawn at its outdoor temperature, starting at zero. The 47°F figure is at one speed; the 17 and 5°F figures are at full speed. The short dark line on each bar is the median of 3-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 1,100 sq ft where winters reach 5°F: heating runs from 26,500 Btu/h at 5°F to 0 at 65°F, and cooling runs from 0 at 65°F to 13,000 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 36,000 Btu heat pumps

3-ton central models

This pairing at 5°F: 17,600 Btu/h
This unit at 5°F median across its pairings: 17,600 Btu/h
Median of 3-ton central models at 5°F: 26,400 Btu/h
Models in this group: 451

This unit is above 17% of them, at number 375 of 451 by heat at 5°F. The middle half of the group runs 18,650 to 32,000 Btu/h.

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

Among 36,000 Btu central models, each by its median certified pairing, highest first: 5°F output as a share of its 47°F rating, 376th of 451 (tied); HSPF2, 363rd of 467 (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.

50VR-K36---30: The same 34,400 Btu/h rating at 47°F; 12,700 Btu/h at 5°F (this model: 17,600).

Floor area at the cold test point

The median certified output of 17,600 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	420–730
Mild	Typical	16–26	680–1,100
Mild	Tight, well insulated	10–18	980–1,760
Cold	Drafty, little insulation	28–52	340–630
Cold	Typical	18–30	590–980
Cold	Tight, well insulated	12–22	800–1,470
Very cold	Drafty, little insulation	32–58	300–550
Very cold	Typical	22–38	460–800
Very cold	Tight, well insulated	16–28	630–1,100

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.

Field definitions

COP: Heat delivered for each unit of electricity used. A COP of 2.5 gives 2.5 times the heat of an electric baseboard heater.
HSPF2: Heating efficiency over a typical season. Higher uses less electricity.
SEER2: Cooling efficiency over a typical season. Higher uses less electricity.
EER2: Cooling output divided by electrical input in the 95°F full-load test, in Btu/h per watt.
Cold output: Heat output at 5°F as a percentage of the 47°F rating.
% of rating at 17°F: Heat output at 17°F as a percentage of the 47°F rating.
