This pairing delivers 31,000 Btu/h of heat at 47°F, 18,200 Btu/h at 17°F, and 18,700 Btu/h at 5°F, 60% of its 47°F rating. It delivers 30,000 Btu/h of cooling at 95°F. At 5°F that is 3,800 Btu/h short of the example heating load of 22,500 Btu/h; at 95°F it is 18,500 Btu/h above the example cooling load of 11,500 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 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 950 sq ft where winters reach 5°F: heating runs from 22,500 Btu/h at 5°F to 0 at 65°F, and cooling runs from 0 at 65°F to 11,500 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 central models

This pairing at 5°F: 18,700 Btu/h
This unit at 5°F median across its pairings: 18,700 Btu/h
Median of 2.5-ton central models at 5°F: 22,400 Btu/h
Models in this group: 288

This unit is above 38% of them, at number 178 of 288 by heat at 5°F. The middle half of the group runs 14,250 to 30,000 Btu/h.

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

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.

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.
