What is the SEER2 rating of the American Standard N5HP5024A1?

The American Standard N5HP5024A1 is rated at up to 16.0 SEER2 and 12.0 EER2 for cooling and up to 8.1 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 162 certified matchups SEER2 ranges from 15.2-16.0.

Is the American Standard N5HP5024A1 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 American Standard N5HP5024A1 cost to run per year?

At its rated efficiency it costs about $697-$1,710 a year in electricity in large U.S. cities, depending on climate and local rates - for example $842 in Phoenix and $1,411 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 American Standard N5HP5024A1?

ENERGY STAR lists 162 certified combinations for this outdoor unit. The highest-rated ones use A5AHV005A1D3+TDR+TSTAT, A5AHV004A1D3+TDR+TSTAT, 5TXCB006AS3+TSTAT+P0V0A000M30SD.

2-ton central heat pump · Bronze 15

American Standard N5HP5024A1

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

Ranks #285 of 331 2 ton central heat pumps for cooling efficiency, and costs about $732 a year to run in a mixed climate like Atlanta.

A good fit if…

You want a choice of indoor units - 162 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.
Comfort and noise matter - a single-stage compressor runs only full-on or off.
