What is the SEER2 rating of the Ducane 4HP17L18P-**A?

The Ducane 4HP17L18P-**A is rated at up to 16.8 SEER2 and 13.5 EER2 for cooling and up to 8.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 1373 certified matchups SEER2 ranges from 15.2-16.8.

Is the Ducane 4HP17L18P-**A good for cold climates?

It is not cold-climate certified: none of its matchups meet the ENERGY STAR cold-climate criteria (a COP of at least 1.75 at 5°F among other limits). In places with frequent sub-zero nights, pick a cold-climate 1.5-ton model.

How much does the Ducane 4HP17L18P-**A cost to run per year?

At its rated efficiency it costs about $503-$1,303 a year in electricity in large U.S. cities, depending on climate and local rates - for example $614 in Phoenix and $1,084 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Which indoor units work with the Ducane 4HP17L18P-**A?

ENERGY STAR lists 1373 certified combinations for this outdoor unit. The highest-rated ones use EA(C;U)1P30A+TDR+TXV, EAC4X30B+TDR, EAC4X30A+TDR.

What refrigerant does the Ducane 4HP17L18P-**A use?

It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and R-32.

1.5-ton central heat pump · 4HP17L Series

Ducane 4HP17L18P-**A

Average cooling efficiency and below average heating efficiency for a 1.5-ton central heat pump, but not rated for cold climates.

Ranks #77 of 170 1.5 ton central heat pumps for cooling efficiency, and costs about $549 a year to run in a mixed climate like Atlanta.

A good fit if…

You want a choice of indoor units - 1,373 certified pairings.

Think twice if…

You often see nights below 0°F - it is not cold-climate certified.
You mainly need heat - its HSPF2 is below average for central heat pumps.
You want the newest refrigerant - it uses R-410A, which is being phased down.
Comfort and noise matter - a single-stage compressor runs only full-on or off.

Questions5

What is the SEER2 rating of the Ducane 4HP17L18P-**A?: The Ducane 4HP17L18P-**A is rated at up to 16.8 SEER2 and 13.5 EER2 for cooling and up to 8.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 1373 certified matchups SEER2 ranges from 15.2-16.8.
Is the Ducane 4HP17L18P-**A good for cold climates?: It is not cold-climate certified: none of its matchups meet the ENERGY STAR cold-climate criteria (a COP of at least 1.75 at 5°F among other limits). In places with frequent sub-zero nights, pick a cold-climate 1.5-ton model.
How much does the Ducane 4HP17L18P-**A cost to run per year?: At its rated efficiency it costs about $503-$1,303 a year in electricity in large U.S. cities, depending on climate and local rates - for example $614 in Phoenix and $1,084 in Minneapolis.
