What is the SEER2 rating of the Ducane 4HP17L42P-**A?

The Ducane 4HP17L42P-**A is rated at up to 15.6 SEER2 and 13.0 EER2 for cooling and up to 8.3 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 349 certified matchups SEER2 ranges from 15.2-15.6.

Is the Ducane 4HP17L42P-**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 3.5-ton model.

How much does the Ducane 4HP17L42P-**A cost to run per year?

At its rated efficiency it costs about $1,231-$3,032 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,482 in Phoenix and $2,506 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 4HP17L42P-**A?

ENERGY STAR lists 349 certified combinations for this outdoor unit. The highest-rated ones use BCE7E42M*4X, EAD4X-48C+TDR, 7ED48CX-0*+TDR.

What refrigerant does the Ducane 4HP17L42P-**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.

A good fit if…

You want a choice of indoor units - 349 certified pairings.

Think twice if…

You often see nights below 0°F - it is not cold-climate certified.
Cooling cost matters most - its SEER2 is below average for central heat pumps.
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.

Questions5

What is the SEER2 rating of the Ducane 4HP17L42P-**A?: The Ducane 4HP17L42P-**A is rated at up to 15.6 SEER2 and 13.0 EER2 for cooling and up to 8.3 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 349 certified matchups SEER2 ranges from 15.2-15.6.
Is the Ducane 4HP17L42P-**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 3.5-ton model.
How much does the Ducane 4HP17L42P-**A cost to run per year?: At its rated efficiency it costs about $1,231-$3,032 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,482 in Phoenix and $2,506 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 4HP17L42P-**A?: ENERGY STAR lists 349 certified combinations for this outdoor unit. The highest-rated ones use BCE7E42M*4X, EAD4X-48C+TDR, 7ED48CX-0*+TDR.
