What is the SEER2 rating of the Concord 4HP17L24P-**A?

The Concord 4HP17L24P-**A is rated at up to 17.0 SEER2 and 14.0 EER2 for cooling and up to 8.2 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 1372 certified matchups SEER2 ranges from 15.4-17.0.

Is the Concord 4HP17L24P-**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 2-ton model.

How much does the Concord 4HP17L24P-**A cost to run per year?

At its rated efficiency it costs about $646-$1,676 a year in electricity in large U.S. cities, depending on climate and local rates - for example $789 in Phoenix and $1,395 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 Concord 4HP17L24P-**A?

ENERGY STAR lists 1372 certified combinations for this outdoor unit. The highest-rated ones use EAH1P30B*+TDR+TXV, 7EH30BX-0*+TDR.

What refrigerant does the Concord 4HP17L24P-**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.

2-ton central heat pump · 4HP17L SERIES

Concord 4HP17L24P-**A

Average cooling efficiency and below average heating efficiency for a 2-ton central heat pump, but not rated for cold climates.

Ranks #234 of 331 2 ton central heat pumps for cooling efficiency, and costs about $706 a year to run in a mixed climate like Atlanta.

A good fit if…

You want a choice of indoor units - 1,372 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 Concord 4HP17L24P-**A?: The Concord 4HP17L24P-**A is rated at up to 17.0 SEER2 and 14.0 EER2 for cooling and up to 8.2 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 1372 certified matchups SEER2 ranges from 15.4-17.0.
Is the Concord 4HP17L24P-**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 2-ton model.
How much does the Concord 4HP17L24P-**A cost to run per year?: At its rated efficiency it costs about $646-$1,676 a year in electricity in large U.S. cities, depending on climate and local rates - for example $789 in Phoenix and $1,395 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 Concord 4HP17L24P-**A?: ENERGY STAR lists 1372 certified combinations for this outdoor unit. The highest-rated ones use EAH1P30B*+TDR+TXV, 7EH30BX-0*+TDR.
