Cold-climate certified heat pumps

6,618 certified units by size, with the heat each size is certified to deliver at 5°F. Pick the size on your quote.

EPA grants its cold-climate designation on a separately measured test, not on the figures shown here. How the designation is defined

At your ZIP

Your heating design temperature and hours below 5°F.

Output at your design temperature is not estimated.

The most efficient cold-climate heat pumps

Ranked by HSPF2, then heat output at 5°F, highest first. One row stands for each set of certified figures.

HSPF2, SEER2, and both outputs are the unit's median certified pairing.

For cooling: the most efficient heat pumps, by SEER2

Certified output at 5°F

2,952 tier-1 units with a certified 5°F heating figure are included here: one representative per distinct set of certified figures, including units with and without the cold-climate designation.

66 units whose 5°F share is outside 40–130% of the 47°F rating are left out of these figures; their unit pages print the figures unchanged.

The table above selects 100 designated cold-climate units by heating efficiency (HSPF2), then heat at 5°F; the full lists are available by size, by state and province, and by model number.

Output by type

Central means ducted split systems and packaged units. Shares use each unit's median certified pairing percentage at 5°F compared with its 47°F rating.

  • Central: 1,119 units with a 5°F figure. Of 1,119 with a 47°F comparison, 89 deliver at least 100% and 699 deliver at least 70% of their 47°F rating at 5°F. The median share is 74% (tests at different compressor speeds).
  • Mini-split: 1,833 units with a 5°F figure. Of 1,831 with a 47°F comparison, 330 deliver at least 100% and 1,572 deliver at least 70% of their 47°F rating at 5°F. The median share is 80% (tests at different compressor speeds).

Output ranges by size class

Each range runs from the lowest to the highest median certified 5°F output in the full population above, split by type. Size classes name nominal cooling capacity. Each size links to its cold-climate-designated units.

Regional design temperatures

Regional median winter design temperatures range from −27°F in Saskatchewan to 63°F in Hawaii. The design temperature is the annual 99% value in the US (about 88 hours a year fall below it) and the 99.6% value in Canada (about 35 hours).

Where the design temperature is below 5°F, the coldest hours of the year fall below the certified test point.

The share is heat output at 5°F divided by the 47°F rating. Tests use different compressor speeds.
